Step-by-step explanation:

5 faces, 8 edges and 5 vertices.

The expression for the required combined function (f ∘ h)(x) is:

54/(12−5x)³ + 8

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input

Given:

F(x) =2x³ +8h(x)

= 3/(12−5x)

We need to write (f ∘ h)(x) as an expression in terms of x, we need to find h(x) first.

Now, we need to find (f ∘ h)(x), which means we need to substitute h(x) in place of x in f(x).

f(x) = 2x³ + 8, therefore,

(f ∘ h)(x) = f(h(x))

= 2h(x)³ + 8

Substitute h(x)3/(12−5x) for x,

(f ∘ h)(x) = 2(h(x))³ + 8

= 2[3/(12−5x)]³ + 8

= 2(27/(12−5x)³) + 8= 54/(12−5x)³ + 8

The correct answer is d. 155. We need a whole number for the sample size, we round up to the nearest whole number.

Therefore, the required sample size is approximately 155.

To determine the sample size needed for a z-test with 95% power and a significance level of 0.05, we can use power analysis. Given the following hypotheses and parameters:

H0: μ = 10 (null hypothesis)

HA: μ ≠ 10 (alternative hypothesis)

σ = 6.9 (standard deviation)

Desired power (1 - β) = 0.95

Significance level (α) = 0.05

We can use a power analysis formula to calculate the required sample size:

n = [(Zα/2 + Zβ) × σ / (μ0 - μA)]²

Where:

Zα/2 is the critical value for a two-tailed test at a significance level of α/2.

Zβ is the critical value corresponding to the desired power.

Let's calculate the required sample size:

Zα/2 = Z(0.05/2) = Z(0.025) ≈ 1.96 (from the standard normal distribution table)

Zβ = Z(0.95) ≈ 1.645 (from the standard normal distribution table)

n = [(1.96 + 1.645) × 6.9 / (10 - 12)]²

n ≈ [3.605 × 6.9 / -2]²

n ≈ [-24.870 / 2]²

n ≈ -12.435²

n ≈ 154.51

Since we need a whole number for the sample size, we round up to the nearest whole number.

Therefore, the required sample size is approximately 155.

The closest option provided is:

The answer of the given question based on the trajectory projection is , the time golf ball takes 1 or 1/2 seconds to hit the ground.

To find out how long it takes Kayley's golf ball to hit the ground, we need to determine when the height h of the golf ball is equal to zero.

So, we can find the time t when the golf ball hits the ground by setting h equal to zero and solving for t in the given equation.

h = -16t² + 20t - 4

When the ball hits the ground, the height h will be zero.

Therefore ,-16t² + 20t - 4 = 0

Factor the left side of the equation to obtain,

-4(4t² - 5t + 1) = 0

We need to find the values of t for which the quadratic factor 4t² - 5t + 1 is equal to zero.

So, let us solve the quadratic factor as follows.

4t² - 5t + 1 = 0

The roots of the quadratic equation

ax² + bx + c = 0,

where a, b, and c are constants and a ≠ 0, are given by

x = (-b ± √(b² - 4ac)) / 2a

Substituting a = 4, b = -5, and c = 1, we get,

t = [-(-5) ± √((-5)² - 4(4)(1))] / 2(4)t

= (5 ± √9) / 8t

= (5 + 3) / 8 or (5 - 3) / 8t

The costs of carrying inventory do not include the interest on funds tied up in inventory. The firm's operating income at sales of 30,000 units will be $30,000. The correct answer is $30,000.

Calculate the firm's operating income at sales of 30,000 units, we first need to calculate the total contribution margin, which is the contribution margin per unit multiplied by the number of units sold:
Contribution margin per unit = $3.00
Number of units sold = 30,000
Total contribution margin = $3.00 x 30,000 = $90,000
Next, we can calculate the firm's total operating expenses, which are the fixed costs of $60,000:
Total operating expenses = $60,000
Finally, we can calculate the firm's operating income by subtracting the total operating expenses from the total contribution margin:
Operating income = Total contribution margin - Total operating expenses
Operating income = $90,000 - $60,000
Operating income = $30,000
Therefore, the firm's operating income at sales of 30,000 units will be $30,000. The correct answer is $30,000.

A graph G(k, n) with a fixed k will have an Euler cycle if n is an even number, ensuring that all vertices have an even degree and the graph is connected.

An Euler cycle, also known as an Eulerian circuit, is a path in a graph that traverses each edge exactly once and returns to its starting point. Let's assume that an undirected graph represented as G(k, n) with k representing the number of vertices and n being the degree of each vertex.

For a graph to have an Euler cycle, it must satisfy two conditions: (1) The graph must be connected, meaning there are no isolated vertices, and (2) all vertices in the graph must have an even degree. The degree of a vertex is the number of edges connected to it.

As your question asks for the values of n for which kn has an Euler cycle, it's important to note that k is fixed, and n will determine whether the graph has an Euler cycle. Since all vertices must have an even degree, it's clear that n must be an even number. Therefore, the values of n for which kn has an Euler cycle are even numbers (e.g., 2, 4, 6, 8, etc.).

The solution of the function is y(t) = C₁(1 + t) + C₂[tex]e^t + (1/2)t^{2e^{(2t)}}[/tex]

Let's start with the homogeneous part of the equation, which is given by:

ty" − (1 + t)y' + y = 0

A function y(t) is said to be a solution of this homogeneous equation if it satisfies the above equation for all values of t. In other words, we need to plug in y(t) into the equation and check if it reduces to 0.

Let's first check if y₁(t) = 1 + t is a solution of the homogeneous equation:

ty₁'' − (1 + t)y₁' + y₁ = t[(1 + t) - 1 - t + 1 + t] = t²

Since the left-hand side of the equation is equal to t² and the right-hand side is also equal to t², we can conclude that y₁(t) = 1 + t is indeed a solution of the homogeneous equation.

Similarly, we can check if y₂(t) = [tex]e^t[/tex] is a solution of the homogeneous equation:

ty₂'' − (1 + t)y₂' + y₂ = [tex]te^t - (1 + t)e^t + e^t[/tex] = 0

Since the left-hand side of the equation is equal to 0 and the right-hand side is also equal to 0, we can conclude that y₂(t) = [tex]e^t[/tex] is also a solution of the homogeneous equation.

Now that we have verified that y₁ and y₂ are solutions of the homogeneous equation, we can move on to finding a particular solution of the nonhomogeneous equation.

To do this, we will use the method of undetermined coefficients. We will assume that the particular solution has the form:

[tex]y_p(t) = At^2e^{2t}[/tex]

where A is a constant to be determined.

We can now substitute this particular solution into the nonhomogeneous equation:

[tex]t(A(4e^{2t}) + 4Ate^{2t} + 2Ate^{2t} - (1 + t)(2Ate^{2t} + 2Ae^{2t}) + At^{2e^{2t}} = t^{2e^{(2t)}}[/tex]

Simplifying the above equation, we get:

[tex](At^2 + 2Ate^{2t}) = t^2[/tex]

Comparing coefficients, we get:

A = 1/2

Therefore, the particular solution of the nonhomogeneous equation is:

[tex]y_p(t) = (1/2)t^2e^{2t}[/tex]

And the general solution of the nonhomogeneous equation is:

y(t) = C₁(1 + t) + C₂[tex]e^t + (1/2)t^{2e^{(2t)}}[/tex]

where C₁ and C₂ are constants that can be determined from initial or boundary conditions.

The expression n(n+1)(n-1) is divisible by 6 for any non-negative integer n, we have proved that 6 divides n^3 - n for any non-negative integer n.

To prove that 6 divides n^3 - n for any non-negative integer n, we need to show that there exists an integer k such that n^3 - n = 6k.

We can start by factoring out n from the expression n^3 - n:

n^3 - n = n(n^2 - 1)

We can further factor n^2 - 1 as (n+1)(n-1):

n^3 - n = n(n+1)(n-1)

Now, we need to show that 6 divides the product n(n+1)(n-1) for any non-negative integer n. We can do this by considering three cases:

Case 1: n is even.

If n is even, then n-1 and n+1 are consecutive odd integers. Thus, one of them is divisible by 3, and the other is divisible by 2. Therefore, their product (n+1)(n-1) is divisible by 6. Also, n is divisible by 2, so the product n(n+1)(n-1) is divisible by 2*6=12, and hence by 6.

Case 2: n is a multiple of 3.

If n is a multiple of 3, then either n+1 or n-1 is a multiple of 2, and the other is a multiple of 4. Also, one of them is a multiple of 3. Therefore, their product (n+1)(n-1) is divisible by 243=24. Also, n is divisible by 3, so the product n(n+1)(n-1) is divisible by 3*24=72, and hence by 6.

Case 3: n is odd and not a multiple of 3.

If n is odd and not a multiple of 3, then n-1 and n+1 are consecutive even integers. Thus, one of them is divisible by 2 and the other is divisible by 4. Therefore, their product (n+1)(n-1) is divisible by 8. Also, n is odd, so the product n(n+1)(n-1) is divisible by 3*8=24, and hence by 6.

Since the expression n(n+1)(n-1) is divisible by 6 for any non-negative integer n, we have proved that 6 divides n^3 - n for any non-negative integer n.

We have proved that 6 divides n^3 - n for any non-negative integer n by induction.

To prove that 6 divides n^3 - n for any non-negative integer n, we need to show that there exists an integer k such that n^3 - n = 6k.

Let's proceed with a proof by induction:

Base case:

For n = 0, we have 0^3 - 0 = 0, which is divisible by 6 (as 0 is divisible by any integer).

Inductive step:

Assume the statement holds true for some arbitrary positive integer k, i.e., k^3 - k = 6m for some integer m.

We need to prove that the statement holds true for k + 1, i.e., (k + 1)^3 - (k + 1) = 6p for some integer p.

Expanding (k + 1)^3 - (k + 1):

(k + 1)^3 - (k + 1) = (k^3 + 3k^2 + 3k + 1) - (k + 1)

= k^3 + 3k^2 + 3k + 1 - k - 1

= k^3 + 3k^2 + 2k

Now, let's substitute the assumption that k^3 - k = 6m:

k^3 + 3k^2 + 2k = 6m + 3k^2 + 2k

= 6m + k(3k + 2)

Since 3k + 2 is an integer, let's denote it as q, where q = 3k + 2.

Now we have:

(k + 1)^3 - (k + 1) = 6m + qk

As we can see, (k + 1)^3 - (k + 1) can be expressed as 6 times an integer (m) plus qk, which is divisible by 6.

The function in question is not provided, so I cannot give you the specific MacLaurin series. However, I can explain how to find the first 3 non-zero terms of a MacLaurin series for a given function.A MacLaurin series is a way to represent a function as an infinite sum of terms. The terms are determined by taking the derivatives of the function at 0 and dividing by the corresponding factorial.

The general formula for the nth term of a MacLaurin series is:
f^(n)(0)/n!
where f^(n) is the nth derivative of the function evaluated at 0.
To find the first 3 non-zero terms of a MacLaurin series, we need to find the first three derivatives of the function at 0 and divide by the corresponding factorials. Then, we can write out the sum of these terms. For example, if the function is f(x) = sin(x), the first three derivatives are:
f'(x) = cos(x)
f''(x) = -sin(x)
f'''(x) = -cos(x)
Evaluating these derivatives at 0 gives:
f'(0) = 1
f''(0) = 0
f'''(0) = -1
Dividing by the corresponding factorials gives:
f'(0)/1! = 1
f''(0)/2! = 0
f'''(0)/3! = -1/6
So, the first 3 non-zero terms of the MacLaurin series for sin(x) are:
sin(x) = x - x^3/3! + x^5/5! + ...
To integrate a function using a MacLaurin series, we can integrate each term of the series term by term. This can be useful for finding approximations of integrals that are difficult to evaluate directly.

If the player rolls doubles again, the player earns 9 more points. Now, we need to find out how many points should the player lose for not rolling doubles in order to make this a fair game.Let's suppose that the probability of rolling doubles is 'P' and the probability of not rolling doubles is '1-P.'After rolling the first time, there are only 6 ways to roll doubles, out of a total of 36 possibilities. So the probability of rolling doubles on the first roll is:P = 6/36 = 1/6(Another way to see this is to notice that there are six pairs of identical dice, so each pair has a 1/6 chance of being rolled.)If the player rolls doubles on the first roll, the player earns 3 points and gets another roll.

The probability of rolling doubles on the second roll is also 1/6. If the player succeeds, the player earns 9 more points. The probability of rolling doubles twice in a row is:P × P = (1/6) × (1/6) = 1/36So, the total expected score from two rolls is:P × 3 + (1 - P) × 0 + P × (1/6) × 9 = 3/6 × P + 3/36 × P = 11/36 × PNow, let X be the number of points lost for not rolling doubles. If the game is fair, then the expected score from two rolls must be the same as the expected score from two rolls plus the expected number of points lost:X = (1 - P) × 11/36 × P = 11/36 × P - 11/36 × P²Now, we need to solve the equation for X to determine the number of points lost for not rolling doubles:11/36 × P - 11/36 × P² = 11/36 × (1/6) - 11/36 × (1/6)²11/36 × P - 11/36 × P² = 11/216 - 11/1296Simplifying the expression:11/36 × P - 11/36 × P² = (2376 - 396)/23328Solving the expression:11/36 × P - 11/36 × P² = 1980/23328Reducing:11P - 11P² = 330P - 330P²11P² - 319P + 0 = 0(11P - 1)(P - 0) = 0P = 1/11 or P = 0Since P cannot be zero, we must take P = 1/11. Therefore, the probability of not rolling doubles is 1 - 1/11 = 10/11.

The expected number of points lost for not rolling doubles is:X = (1 - P) × 11/36 × P = 10/11 × 11/36 × 1/11 = 1/36Therefore, the player should lose 1 point for not rolling doubles in order to make this a fair game. Hence, the correct option is 1.

The coordinates of line segment A'B' after the transformation are (10k, 5k) and (-10k, -5k).

Explanation: The given line segment AB is dilated with a scale factor of k and center of dilation at the origin O. The coordinates of the endpoints of AB are A(x1, y1) and B(x2, y2), so the coordinates of the endpoints of the dilated line segment AB' are A'(kx1, ky1) and B'(kx2, ky2).Now, the reflected line segment of AB' over the y-axis is A''(-kx1, ky1) and B''(-kx2, ky2).After that, the reflected line segment is dilated with a scale factor of k and center of dilation at C(5,5), so the coordinates of the endpoints of the final line segment A'B' are (k(-kx1 + 5) + 5, k(ky1 - 5) + 5) and (k(-kx2 + 5) + 5, k(ky2 - 5) + 5) which simplify to (10k, 5k) and (-10k, -5k). Thus, the coordinates of line segment A'B' after the transformation are (10k, 5k) and (-10k, -5k).

The correct response is True. The census in Numbers 1 is focused on counting men who are eligible for military service.

Specifically, this census was conducted to determine the number of men aged 20 years and older from each tribe of Israel, as these individuals were considered to be of appropriate age for warfare. This process was vital for assessing the military strength of the Israelite community and allocating resources effectively. While the census data did not include women, children, or men below the specified age limit, it provided valuable information for planning military strategies and understanding the demographics of the Israelite population.

The census in Numbers 1 specifically mentions that the count is of men who are twenty years old or older and who are able to serve in the army. This indicates that the purpose of the census was to assess the military strength of the Israelites. Women and children were not included in this count. It is also worth noting that in ancient societies, military service was often restricted to men, which further supports the idea that this census was focused on male military readiness. Overall, the census in Numbers 1 provides insight into the gender roles and military priorities of the Israelite society at the time.

the cost of preferred stock is approximately 13.6%.

Hatter Inc.'s weighted average cost of capital (WACC) is approximately 11.5%.

Given:

Annual dividend = $9.50

Current market price = $79.16

Floatation costs = 12% = 0.12

First, we calculate the net issuing price:

Net issuing price = Current market price - Floatation costs * Current market price

                = $79.16 - 0.12 * $79.16

                = $79.16 - $9.50

                = $69.66

Next, we calculate the cost of preferred stock:

Cost of preferred stock = Annual dividend / Net issuing price

                      = $9.50 / $69.66

                      ≈ 0.136 or 13.6%

Therefore, the cost of preferred stock is approximately 13.6%.

Now let's move on to calculating Hatter Inc.'s weighted average cost of capital (WACC).

Given:

Tax rate = 30%

To calculate WACC, we need to determine the weighted average cost of each capital component and then sum them up based on their weights.

Debt cost = 10%

Preferred stock cost = 12%

Common equity cost = 14%

Weight of debt = Debt value / Total value of capital components

             = $15,500 / ($15,500 + $7,500 + $10,000)

             ≈ 0.50 or 50%

Weight of preferred stock = Preferred stock value / Total value of capital components

                        = $7,500 / ($15,500 + $7,500 + $10,000)

                        ≈ 0.25 or 25%

Weight of common equity = Common equity value / Total value of capital components

                      = $10,000 / ($15,500 + $7,500 + $10,000)

                      ≈ 0.25 or 25%

Now, we can calculate the WACC:

WACC = (Weight of debt * Debt cost) + (Weight of preferred stock * Preferred stock cost) + (Weight of common equity * Common equity cost)

    = (0.50 * 0.10) + (0.25 * 0.12) + (0.25 * 0.14)

    = 0.05 + 0.03 + 0.035

    ≈ 0.115 or 11.5%

Therefore, Hatter Inc.'s weighted average cost of capital (WACC) is approximately 11.5%.

Now let's move on to the internal rate of return (IRR) calculation for the project.

Given:

Initial outlay = $90,000

Net cash inflows per year = $28,000 (for the next 5 years)

The internal rate of return (IRR) is the discount rate that makes the net present value (NPV) of the project equal to zero. In other words, it is the rate at which the present value of the cash inflows equals the initial outlay.

To calculate the IRR, we need to find the discount rate that solves the following equation:

0 = -Initial outlay + (Net cash inflow / (1 + r)^1) + (Net cash inflow / (1 + r)^2) + ... + (Net cash inflow / (1 + r)^5)

Where r is the discount rate (IRR).

Answer: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle. That is, in ΔABC, if c2=a2+b2 then ∠C is a right triangle, ΔPQR being the right angle.

To test whether the data come from a Poisson distribution, we will use the chi-squared goodness-of-fit test. The null hypothesis is that the data follow a Poisson distribution, and the alternative hypothesis is that they do not.

First, we need to calculate the expected frequencies under the Poisson distribution assumption. The mean of the Poisson distribution can be estimated as the sample mean, which is:

λ = (1 × 296 + 2 × 61 + 3 × 11) / (296 + 61 + 11) = 0.981

Then, we can calculate the expected frequencies for each category as:

Expected frequency = e = (e^-λ * λ^k) / k!

where k is the number of accidents and λ is the mean.

The expected frequencies for each category are:

k = 0: e = (e^-0.981 * 0.981^0) / 0! = 0.375

k = 1: e = (e^-0.981 * 0.981^1) / 1! = 0.367

k = 2: e = (e^-0.981 * 0.981^2) / 2! = 0.180

k ≥ 3: e = 1 - (0.375 + 0.367 + 0.180) = 0.078

The expected frequencies for k ≥ 3 are combined because there are only 11 observations in this category.

We can now calculate the chi-squared statistic:

χ² = Σ (O - E)² / E

where O is the observed frequency and E is the expected frequency.

The observed frequencies and corresponding expected frequencies are:

k O E

0 296 0.375

1 61 0.367

2 11 0.180

3+ 11 0.078

Using these values, we calculate the chi-squared statistic as:

χ² = (296 - 0.375)² / 0.375 + (61 - 0.367)² / 0.367 + (11 - 0.180)² / 0.180 + (11 - 0.078)² / 0.078

= 542.63

The degrees of freedom for this test are d.f. = k - 1 - p, where k is the number of categories (4 in this case) and p is the number of parameters estimated (1 for the Poisson distribution mean). So, d.f. = 4 - 1 - 1 = 2.

We can look up the critical value of the chi-squared distribution with 2 degrees of freedom and a 5% level of significance in a chi-squared table or calculator. The critical value is 5.991.

Since the calculated chi-squared statistic (542.63) is greater than the critical value (5.991), we reject the null hypothesis that the data follow a Poisson distribution. Therefore, we conclude that there is evidence to suggest that the data do not come from a Poisson distribution.

To evaluate the integral e6x − 5 ex/2 dx, we first need to use the rule for integrating e^ax which is 1/a e^ax + c. Using this rule, we can rewrite the integral as (1/6)e^6x - (2/5)e^(2x) + c. This is because when we integrate e^6x, the constant is 1/6, and when we integrate e^(x/2), the constant is 2/5.
Now we can simplify this expression by finding a common denominator for the constants. The common denominator is 30. So, we can rewrite the expression as (5/30)e^6x - (12/30)e^(2x) + c. Simplifying further, we get (1/6)e^6x - (2/5)e^(2x) + c.

A) For any linear transformation L from R^m to R^n, there exists an orthonormal basis {v1,...,vm} for R^m such that the vectors {L(v1),...,L(vm)} are orthogonal. B) For any linear transformation T from Rm to Rn, where m is less than or equal to n, there exists an orthonormal basis {v1,...,vm} of Rm and an orthonormal basis {w1,...,wn} of Rn such that T(vi) is a scalar multiple of wi, for i=1,...,m.

A) Let A be the matrix representation of L with respect to the standard basis of R^m and R^n. Then A^T A is a symmetric matrix, and we can find an orthonormal basis {v1,...,vm} of R^m consisting of eigenvectors of A^T A. Note that if λ is an eigenvalue of A^T A, then Av is an eigenvector of A corresponding to λ, where v is an eigenvector of A^T A corresponding to λ. Also note that L(vi) = Avi, so the vectors {L(v1),...,L(vm)} are orthogonal.

B) Let A be the matrix representation of T with respect to some orthonormal basis {e1,...,em} of Rm and some orthonormal basis {f1,...,fn} of Rn. We can extend {e1,...,em} to an orthonormal basis {v1,...,vn} of Rn using the Gram-Schmidt process. Then we can define wi = T(ei)/||T(ei)|| for i=1,...,m, which are orthonormal vectors in Rn. Let V be the matrix whose columns are the vectors v1,...,vm, and let W be the matrix whose columns are the vectors w1,...,wn. Then we have TV = AW, where T is the matrix representation of T with respect to the basis {v1,...,vm}, and A is the matrix representation of T with respect to the basis {e1,...,em}. Since A is a square matrix, it is diagonalizable, so we can find an invertible matrix P such that A = PDP^-1, where D is a diagonal matrix. Then we have TV = AW = PDP^-1W, so V^-1TP = DP^-1W. Letting Q = DP^-1W, we have V^-1T = PQ^-1. Since PQ^-1 is an orthogonal matrix (because its columns are orthonormal), we can apply the Gram-Schmidt process to its columns to obtain an orthonormal basis {w1,...,wm} of Rn such that T(vi) is a scalar multiple of wi, for i=1,...,m.

Option A The probability that a randomly selected participant is an adult and prefers comedies is 0.0893.

The probability that a randomly selected participant is either an adult or prefers comedies or both is 0.5507.

we have a sample of 400 moviegoers, and we have to find the probability of a randomly selected participant being an adult and preferring comedies.

we need to use the concepts of set theory and probability.

Let C be the event that the participant is an adult, and let D be the event that the participant prefers comedies. The intersection of the two events (C ∩ D) represents the probability that a randomly selected participant is an adult and prefers comedies. To calculate this probability, we need to multiply the probability of event C by the probability of event D given that event C has occurred.

P(C ∩ D) = P(C) * P(D/C)

From the given data, we can see that the probability of a randomly selected participant being an adult is 0.47 calculated by adding up the entries in the "adults" column and dividing by the total number of participants. Similarly, the probability of a randomly selected participant preferring comedies is 0.17 taken from the "comedy" row and dividing by the total number of participants.

From the given data, we can see that the probability of an adult participant preferring comedies is 0.19 taken from the "comedy" column and dividing by the total number of adult participants.

P(D|C) = 0.19

Therefore, we can calculate the probability of a randomly selected participant being an adult and preferring comedies as:

P(C ∩ D) = P(C) * P(D|C) = 0.47 * 0.19 = 0.0893

So the probability that a randomly selected participant is an adult and prefers comedies is 0.0893.

To calculate the probability of a randomly selected participant being either an adult or preferring comedies or both, we need to use the union of the two events (C ∪ D).

P(C ∪ D) = P(C) + P(D) - P(C ∩ D)

Substituting the values we have calculated, we get:

P(C ∪ D) = 0.47 + 0.17 - 0.0893 = 0.5507

So the probability that a randomly selected participant is either an adult or prefers comedies or both is 0.5507.
