Joe and Hope were both asked to factor the following polynomial completely. Is one of them correct? Both of them? Neither of them? Explain what each of them did that was correct and/or incorrect. EXPLAIN FOR BOTH JOE AS WELL AS HOPE!
Factoring a polynomial involves expressing it as the product of two or more factors. In this case, the polynomial is 4x^2 + 12x - 6.
Here's how Joe and Hope went about factoring the polynomial:
Joe: Joe wrote down the polynomial and tried to factor it using a common factoring technique. He tried to factor out the greatest common factor (GCF), which is 4. He then tried to factor the remaining term, which is 12x - 6, using the difference of squares method. He obtained the factors (2x + 3)(2x - 3).
Hope: Hope also wrote down the polynomial and tried to factor it using a common factoring technique. She tried to factor out the GCF, which is 4. She then tried to factor the remaining term, which is 12x - 6, using the difference of squares method. She obtained the factors (2x + 6)(2x - 3).
Therefore, both Joe and Hope made some errors in their factoring attempts. Joe obtained the incorrect factors (2x + 3)(2x - 3), while Hope obtained the incorrect factors (2x + 6)(2x - 3).
To factor the polynomial completely, we need to find the correct factors. The correct factors are (x + 3)(x - 3), which can be verified by multiplying out the factors and simplifying.
Therefore, neither Joe nor Hope correctly factored the polynomial 4x^2 + 12x - 6.

Consider a resource allocation problem for a Martian base. A fleet of N reconfigurable, general purpose robots is sent to Mars at t= 0. The robots can (i) replicate or (ii) make human habitats. We model this setting as a dynamical system. Let z be the number of robots and b be the number of buildings. Assume that decision variable u is the proportion of robots building new robots (so, u(t) C [0,1]). Then, z(0) N, 6(0) = 0, and z(t)=au(t)r(1), b(1)=8(1 u(t))x(1) where a > 0, and 3> 0 are given constants. Determine how to optimize the tradeoff between (i) and (ii) to result in maximal number of buildings at time T. Find the optimal policy for general constants a>0, 8>0, and T≥ 0.
Overall, this policy balances the tradeoff between (i) and (ii) by allocating robots between replicating and building human habitats in a way that maximizes the number of buildings at time T using Bernoulli differential equation.
To optimize the tradeoff between (i) and (ii) and achieve maximal number of buildings at time T, we need to find the optimal value of u(t) over the time interval [0, T]. We can do this using the calculus of variations.
First, we need to define the objective function that we want to optimize. In this case, we want to maximize the number of buildings at time T, which is given by b(T). Therefore, our objective function is:
J(u) = b(T)
Next, we need to formulate the problem as a constrained optimization problem. The constraints in this case are that the number of robots cannot be negative and the total proportion of robots allocated to building new robots and making buildings must be equal to 1. Mathematically, we can express this as:
z(t) ≥ 0
u(t) + x(t) = 1
where x(t) is the proportion of robots allocated to making buildings.
Now, we can apply the Euler-Lagrange equation to find the optimal value of u(t). The Euler-Lagrange equation is:
d/dt (∂L/∂u') - ∂L/∂u = 0
where L is the Lagrangian, which is given by:
L = J(u) + λ(z(t) - z(0)) + μ(u(t) + x(t) - 1)
where λ and μ are Lagrange multipliers.
We can compute the partial derivatives of L with respect to u and u', and then use the Euler-Lagrange equation to find the optimal value of u(t).
After some algebraic manipulations, we obtain the following differential equation for u(t):
d/dt (u^2(t) (1-u(t))^2) = 4a^2u(t)^2 (1-u(t))^2
This is a Bernoulli differential equation, which can be solved by making the substitution v(t) = u(t) / (1-u(t)). After some further algebraic manipulations, we obtain:
v(t) = C / (1 + C exp(-2at))
where C is a constant of integration.
Finally, we can solve for u(t) in terms of v(t) using the equation u(t) = v(t) / (1 + v(t)).
Therefore, the optimal policy for maximizing the number of buildings at time T is given by:
u*(t) = v*(t) / (1 + v*(t))
where v*(t) is given by v*(t) = C / (1 + C exp(-2at)) with the constant C determined by the initial condition z(0) = N.

find the interval of convergence of ∑=2[infinity](−2)ln(2)
The series diverges when x = -2.
The given series is:
∑n=2^∞ (−2)ln(2) = ∑n=2^∞ ln(2^(-2))
We can write this as a power series in x by setting x = -2:
∑n=2^∞ ln(2^(-2))x^n
The interval of convergence of this power series can be found using the ratio test:
lim┬(n→∞)|((ln(2^(-2))x^(n+1))/ln(2^(-2))x^n)| = |x|
The series will converge if |x| < 1, and diverge if |x| > 1. Therefore, the interval of convergence is -1 < x < 1.
Substituting x = -2, we get:
-1 < -2 < 1
This is not true, so the series diverges when x = -2.

Find the taylor polynomials of degree n approximating 1/(2-2x) for x near 0.
For n = 3, P3(x) = ____
For n= 5, P5(x) = ____
For n = 7, P7(x) = ____
The Taylor polynomials of degree n approximating 1/(2-2x) for x near 0 are:
P3(x) = 1/2 - x + x^2 - x^3/2
P5(x) = 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16
P7(x) = 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16 + 35x^6/64 - 63x^7/128
To find the Taylor polynomials of degree n approximating 1/(2-2x) for x near 0, we need to compute the nth derivatives of the function and evaluate them at x=0. The nth derivative of 1/(2-2x) is:
f^(n)(x) = n!(2-2x)^-(n+1)
evaluated at x=0, we get:
f^(n)(0) = n!(2)^-(n+1) = n!/2^(n+1)
Using this formula, we can find the Taylor polynomial of degree n as follows:
Pn(x) = f(0) + f'(0)x + f''(0)x^2/2! + ... + f^(n)(0)x^n/n!
For n=3:
P3(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3!
= 1/2 - x + x^2 - x^3/2
For n=5:
P5(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3! + f''''(0)x^4/4! + f^(5)(0)x^5/5!
= 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16
For n=7:
P7(x) = f(0) + f'(0)x + f''(0)x^2/2! + f'''(0)x^3/3! + f''''(0)x^4/4! + f^(5)(0)x^5/5! + f^(6)(0)x^6/6! + f^(7)(0)x^7/7!
= 1/2 - x + x^2 - x^3/2 + 3x^4/8 - 5x^5/16 + 35x^6/64 - 63x^7/128
Therefore, the Taylor polynomials of degree n approximating 1/(2-2x) for x near 0 are:

: suppose f : r → r is a differentiable lipschitz continuous function. prove that f 0 is a bounded function
We have shown that if f: R -> R is a differentiable Lipschitz continuous function, then f(0) is a bounded function.
What is Lipschitz continuous function?As f is a Lipschitz continuous function, there exists a constant L such that:
|f(x) - f(y)| <= L|x-y| for all x, y in R.
Since f is differentiable, it follows from the mean value theorem that for any x in R, there exists a point c between 0 and x such that:
f(x) - f(0) = xf'(c)
Taking the absolute value of both sides of this equation and using the Lipschitz continuity of f, we obtain:
|f(x) - f(0)| = |xf'(c)| <= L|x-0| = L|x|
Therefore, we have shown that for any x in R, |f(x) - f(0)| <= L|x|. This implies that f(0) is a bounded function, since for any fixed value of L, there exists a constant M = L|x| such that |f(0)| <= M for all x in R.
In conclusion, we have shown that if f: R -> R is a differentiable Lipschitz continuous function, then f(0) is a bounded function.

When the error terms have a constant variance, a plot of the residuals versus the independent variable x has a pattern that a. Fans out b. Funnels in c. Fans out, but then funnels in d. Forms a horizontal band pattern e. Forms a linear pattern that can be positive or negative
When the error terms have a constant variance, a plot of the residuals versus the independent variable x has a pattern that b. Funnels in
When the error terms have a constant variance, a plot of the residuals (the differences between the observed values and the predicted values) versus the independent variable x often exhibits a funnel-shaped pattern that narrows as the values of x increase or decrease.
This funneling pattern is a characteristic of heteroscedasticity, which refers to the unequal dispersion of the error terms across the range of the independent variable. In other words, the variability of the residuals changes systematically with the values of x.
The funneling pattern occurs because as the values of x increase or decrease, the spread of the residuals tends to increase as well. This can happen when the relationship between the independent variable and the dependent variable is nonlinear or when there are other factors influencing the variability of the residuals.
On a scatterplot of residuals versus x, the points may initially fan out, indicating increasing variability. However, as x continues to increase or decrease, the points start to converge and form a narrower funnel shape, indicating decreasing variability.
This funneling pattern suggests that the assumption of constant variance (homoscedasticity) in a regression model is violated. It is important to address heteroscedasticity to ensure accurate statistical inference and model validity.

One village has 275 houses for people live in each house. How many peoples live in three such villages
There are a couple of ways to approach this problem, but one common method is to use multiplication.
If there are 275 houses in one village, then the total number of people living in that village is:
275 houses x 1 household / house = 275 households
Assuming that each household has an average of 3 people (which is just an estimate), then the total number of people living in one village is:
275 households x 3 people / household = 825 people
To find the total number of people living in three such villages, we can multiply the number of people in one village by 3:
825 people / village x 3 villages = 2475 people
Therefore, there are approximately 2475 people living in three villages with 275 houses each.

2) Let θ be an angle in quadrant II such that = secθ −5/3. Find the exact values of cotθ and sinθ.
3)Determine the quadrant in which the terminal side of θ lie (a) sinθ<0 and cotθ<0 (b)cosθ>0 and cscθ<0
In quadrant II, if cosθ=-12/13, then cscθ=-13/5 and cotθ=5/12.
In quadrant II, if secθ=-5/3, then cotθ=-3/5 and sinθ=4/5.
(a) The terminal side of θ lies in quadrant III. (b) The terminal side of θ lies in quadrant IV.
Since cosθ is negative in quadrant II, sinθ will be positive. Using the Pythagorean identity sin^2θ + cos^2θ = 1 and the fact that cosθ=-12/13, we can solve for sinθ to get sinθ=5/13. Therefore, cscθ=1/sinθ=-13/5 and cotθ=cosθ/sinθ=-12/5.
Similarly, since secθ is negative in quadrant II, cosθ will be negative. Using the Pythagorean identity cos^2θ + sin^2θ = 1 and the fact that secθ=-5/3, we can solve for cosθ to get cosθ=-3/5. Therefore, sinθ is positive and sinθ=√(1-cos^2θ)=4/5. Thus, cotθ=cosθ/sinθ=-3/5.
(a) Since sinθ<0 and cotθ<0, we know that sinθ is negative in quadrant III and cotθ is negative in quadrant II and IV. Therefore, the terminal side of θ can only lie in quadrant III or IV. To determine which quadrant it lies in, we can look at the signs of both sinθ and cotθ. Since both are negative in quadrant III and only cotθ is negative in quadrant IV, we conclude that the terminal side of θ lies in quadrant III.
(b) Since cosθ>0 and cscθ<0, we know that cosθ is positive in quadrant I and IV, and cscθ is negative in quadrant III and IV. Therefore, the terminal side of θ can only lie in quadrant III or IV. To determine which quadrant it lies in, we can look at the signs of both cosθ and cscθ. Since both are negative in quadrant III and only cscθ is negative in quadrant IV, we conclude that the terminal side of θ lies in quadrant IV.

∫ (u^2 + 3u)(u)^(7/2) du
Simplifying further, we have:
∫ (u^9/2 + 3u^(11/2)) du
Now, we can integrate each term separately:
∫ u^9/2 du + ∫ 3u^(11/2) du
Integrating each term, we get:
(u^(11/2 + 2/9))/(11/2 + 2/9) + (2/9)u^(13/2 + 1/9) + c
Simplifying the expressions, we have:
(2/11)u^(11/2 + 2/9) + (2/9)u^(13/2 + 1/9) + c
Finally, substituting back u = x - 3, we have:
(2/11)(x - 3)^(11/2 + 2/9) + (2/9)(x - 3)^(13/2 + 1/9) + c

29). The perimeter of the room is 4x - 32
30). The dimensions of the square vegetable garden are (x - 15) and (x + 15)
Word problems in mathematicsWord problems are mathematical problems which involves the use ofordinary words, instead of mathematical symbols.
Given the area of the room as x² - 16x + 60, we can get the dimensions by factorization as follows:
x² - 16x + 60 = x² - 6x - 10x + 60
x² - 16x + 60 = (x - 6)(x - 10)
perimeter of room = 2[(x - 6) + (x - 10)]
perimeter of room = 2(x + x - 6 - 10)
perimeter of room = 2(2x - 16)
perimeter of room = 4x - 32
The dimensions of the square vegetable garden with an area x² - 255 is derived using the difference of two square;
x² - 255 = x² - 15²
x² - 255 = (x - 15)(x + )
Therefore, the dimensions of the room are (x - 6) and (x -10). The perimeter of the room is 4x - 32. And the dimensions of the square vegetable garden are (x - 15) and (x + 15)

1) The power series ∑(n=0)∞ xn/(n+1)^(2n) converges for all x in (-1,1) by the ratio test.
2) The power series ∑(n=1)∞ (x-1)^n/n converges for x in the interval (0,2), with the endpoints excluded. To see this, we can use the ratio test and find that |(x-1)/(n+1)| → |x-1| as n → ∞. Thus, the series converges absolutely when |x-1| < 1, and diverges when |x-1| > 1. At x = 0, the series is the harmonic series which diverges, and at x = 2, the series becomes the alternating harmonic series which converges but not absolutely.

The series converges if |x+1|/3 < 1, i.e. if -4 < x < 2. The series converges at x=2 and diverges at x=-4, so the convergence set is (-4,2].
For the first power series, we use the ratio test:
lim |(x_{n+1}/(n+2)^{2(n+2)})/(x_n/(n+1)^{2n+2})| = lim |x_{n+1}|(n+1)^{2n+3}/|x_n|(n+2)^{2n+2}
= lim |x_{n+1}/x_n| ((n+1)/(n+2))^{2n+3} (n+1)/(n+2)
= lim |x_{n+1}/x_n| lim ((n+1)/(n+2))^{2n+3} lim (n+1)/(n+2)
= |x| lim (1/4)^n lim 1/2 = 0
Therefore, the series converges for all x.
For the second power series, we also use the ratio test:
lim |((x-1)^(n+1)/(n+1))/((x-1)^n/n)| = lim |x-1| (n+1)/n = |x-1|
Therefore, the series converges if |x-1| < 1 and diverges if |x-1| > 1. The series converges at x=0 and x=2, so the convergence set is [0,2].
For the third power series, we use the ratio test again:
lim |((x-(n+1))/(n+1)) ((x-n)/n!)| = lim |x-(n+1)|/|n+1| lim |x-n|/n! = 0
Therefore, the series converges for all x.
For the fourth power series, we use the root test:

All the angles are,
Angle 1 is 54,
Angle 2 is 54,
Angle 3 equal 36,
Angle 4 is 54
A rhombus diagonals are perpendicular so all the angles in the middle of the rhombus measure is 90 degrees. So this means we are dealing with 4 right congruent triangles.
Since a rhombus is a parallelogram, it opposite sides are parallel. Since there is a line that it cuts through the parallel line, Angle 3 and 36 are alternate interior angles.
Here, Alt. interior angles are congruent so Angle 3 = 36.
In the upper left triangle, angle 3 ,angle 4, and the middle angle form 180 degrees since it a triangle. The middle angle measure 90 degrees. so we can find angle 4.
36 + 90 + x = 180
x = 180 - 126
x = 54
so angle 4=54
And, Angle 4 and Angle 1 are alt. interior angles so that means Angle 1 also equal 54.

The probability that x is less than 1 when n=4 and p=0.3 using the binomial formula, the probability that x is less than 1 when n=4 and p=0.3 is 0.2401.
The probability that x is less than 1 when n=4 and p=0.3 using the binomial formula we can follow these steps:
Identify the parameters.
In this case, n = 4 (number of trials), p = 0.3 (probability of success), and x < 1 (number of successes).
Use the binomial formula.
The binomial formula is P(x) = C(n, x) * p^x * (1-p)^(n-x)
where C(n, x) is the number of combinations of n things taken x at a time.
Calculate the probability for x = 0.
For x = 0, the formula becomes P(0) = C(4, 0) * 0.3^0 * (1-0.3)^(4-0).
C(4, 0) = 1, so P(0) = 1 * 1 * 0.7^4 = 1 * 1 * 0.2401 = 0.2401.
Sum the probabilities for all x values less than 1.
Since x < 1, the only possible value is x = 0.
Therefore, the probability that x is less than 1 when n=4 and p=0.3 is 0.2401.

(For 160,000 it takes 18ms to sort each half. Then merging together the two sorted halves with 80,000 numbers in each of them takes 40-218 = 4 ms. For 320,000 elements, it will take 240 to sort each half and 24 to merge the sorted halves with 160,000 numbers in each, for the total of 240+8 = 88 ms.)
For a larger input size of 320,000 elements, it will take 240 ms to sort each half and 24 ms to merge the sorted halves, resulting in a total time of 264 ms.
The given information describes the time required for sorting and merging operations on two different input sizes. For 80,000 elements, it takes 18 ms to sort each half, resulting in a total of 36 ms for sorting. Merging the two sorted halves with 80,000 numbers in each takes 40 - 18 = 22 ms.
When the input size is doubled to 320,000 elements, the sorting time for each half increases to 240 ms, as it scales linearly with the input size. The merging time, however, remains constant at 4 ms since the size of the sorted halves being merged is the same.
Thus, the total time for sorting and merging 320,000 elements is the sum of the sorting time (240 ms) and the merging time (4 ms), resulting in a total of 264 ms.
Therefore, based on the given information, the total time required for sorting and merging 320,000 elements is 264 ms.

Question 38 0 A poling organization surveyed 2,002 randomly selected adults who are not scientists and 3,748 randomly selected adults who are scientists. Each adult was asked the question, "Do you think that genetically modified foods are safe to eat of those who are not scientists, 37 percent responded yes, and of those who are scientists 88 percent responded yes. Which of the following is the standard error used to construct a confidence interval for the difference between the proportions of all adults who are not scientists and al adults who we scientists who would answer yes to the question?
The standard error for this problem is 0.016.
To calculate the standard error for this problem, we first need to find the proportion of non-scientists who answered yes and the proportion of scientists who answered yes.
For non-scientists:
Number who answered yes = 0.37 * 2002 = 740.74
Proportion who answered yes = 740.74 / 2002 = 0.369
For scientists:
Number who answered yes = 0.88 * 3748 = 3298.24
Proportion who answered yes = 3298.24 / 3748 = 0.879
Next, we can calculate the standard error using the formula:
SE = sqrt[(p1 * (1-p1) / n1) + (p2 * (1-p2) / n2)]
where p1 and p2 are the proportions we just calculated, and n1 and n2 are the sample sizes for each group.
SE = sqrt[(0.369 * (1-0.369) / 2002) + (0.879 * (1-0.879) / 3748)]
SE = 0.016

What would the potential of a standard hydrogen electrode (SHE) be if it was under the following conditions?
[H+]= 0.68 M
PH22 = 2.3 atm
T = 298 K
The potential of the SHE under these conditions is approximately 0.021 V.
The potential of a standard hydrogen electrode (SHE) under the given conditions, [H⁺] = 0.68 M, pH2 = 2.3 atm, and T = 298 K, would be approximately 0.021 V.
To calculate the potential of the SHE, we can use the Nernst equation:
E = E₀ - (RT/nF) * lnQ
where E is the potential, E₀ is the standard potential (0 V for SHE), R is the gas constant (8.314 J/(mol·K)), T is the temperature (298 K), n is the number of electrons (2 for hydrogen), F is Faraday's constant (96,485 C/mol), and Q is the reaction quotient.
For the SHE, Q = ([H⁺]^2 * pH2) / pH20, where pH20 is the standard pressure (1 atm). Plugging in the given values, Q = (0.68^2 * 2.3) / 1.
Now, calculate E using the Nernst equation:
E = 0 - (8.314 * 298 / (2 * 96,485)) * ln(0.68^2 * 2.3)

Find the exact length of the curve. x = 3 3t2, y = 4 2t3, 0 ≤ t ≤ 5
The exact length of the curve is (4/3)(21^(3/4) - 1) units
To find the length of the curve given by x = 3t^2, y = 4t^3, where 0 ≤ t ≤ 5, we need to use the formula:
L = ∫[a,b]sqrt(dx/dt)^2 + (dy/dt)^2 dt
where a and b are the values of t that correspond to the endpoints of the curve.
First, let's find dx/dt and dy/dt:
dx/dt = 6t
dy/dt = 12t^2
Then, we can compute the integrand:
sqrt(dx/dt)^2 + (dy/dt)^2 = sqrt((6t)^2 + (12t^2)^2) = sqrt(36t^2 + 144t^4)
So, the length of the curve is:
L = ∫[0,5]sqrt(36t^2 + 144t^4) dt
We can simplify this integral by factoring out 6t^2 from the square root:
L = ∫[0,5]6t^2sqrt(1 + 4t^2) dt
To evaluate this integral, we can use the substitution u = 1 + 4t^2, du/dt = 8t, dt = du/8t:
L = ∫[1,21]3/4sqrt(u) du
Now, we can use the power rule of integration to evaluate the integral:
L = (4/3)(u^(3/4))/3/4|[1,21]
L = (4/3)(21^(3/4) - 1^(3/4))
L = (4/3)(21^(3/4) - 1)

The curvature κ(t) is given by |6 / (2 + 3t²)³|.
To find the curvature κ(t) for the given parametric equations x = 9 + t² and y = 3 + t³, we need to use the formula:
κ(t) = |(x'y'' - y'x'') / (x'² + y'²)^(3/2)|
where x' and y' represent the first derivatives with respect to t, and x'' and y'' represent the second derivatives with respect to t.
Let's find the derivatives first:
Given:
x = 9 + t²
y = 3 + t³
First derivatives:
x' = 2t
y' = 3t²
Second derivatives:
x'' = 2
y'' = 6t
Now, we can substitute these values into the curvature formula:
κ(t) = |(x'y'' - y'x'') / (x'²+ y'²)^(3/2)|
= |((2t)(6t) - (3t²)(2)) / ((2t)² + (3t²)²)^(3/2)|
= |(12t² - 6t²) / (4t² + 9t[tex]x^{4}[/tex])^(3/2)|
= |(6t²) / (t²(4 + 9t²))^(3/2)|
= |(6t²) / (t²(√(4 + 9t²)))³|
= |(6t²) / (t² * (2 + 3t²))³|

Let Y1, ..., Y100 be independent Uniform(0, 2) random variables.
a) Compute P[2Y< 1.9]
b) Compute P[Y(n) < 1.9]
a) P[2Y< 1.9]
Let Z = 2Y. Then Z ~ Uniform(0, 4)
1.9 is in the support of Z.
So P[Z< 1.9] = (1.9)/4 = 0.475
b) P[Y(n) < 1.9]
Y(n) is the n^th order statistic of Y1, ..., Y100. Since the Yi's are Uniform(0, 2), Y(n) ~ Beta(n, 100-n+1)
To find P[Y(n) < 1.9], we evaluate the CDF of the Beta distribution at 1.9.
Since n is not given, we consider the extremes:
n = 1: Y(1) ~ Uniform(0, 2) so P[Y(1) < 1.9] = 1.9/2 = 0.95
n = 100: Y(100) ~ Beta(100, 1) so P[Y(100) < 1.9] = 0 (since 1.9 > 2)
Therefore, 0.95 < P[Y(n) < 1.9] < 1 for any n.
In summary:
a) P[2Y< 1.9] = 0.475
b) 0.95 < P[Y(n) < 1.9] < 1 for any n.
Let me know if you have any other questions!
For content loaded , Y1, ..., Y100 as independent Uniform(0, 2) random variables.
a) P[2Y< 1.9]: = 0.475.
b) P[Y(n) < 1.9] = 0.994.
a) To solve this problem, we first need to find the distribution of 2Y. Since Y ~ Uniform(0, 2), we have that 2Y ~ Uniform(0, 4). Therefore, we can rewrite the probability as P[2Y < 1.9] = P[Y < 0.95].
Now, we know that the distribution of Y is continuous and uniform, so the probability that Y is less than any specific value a is equal to (a - 0)/(2 - 0) = a/2. Therefore, P[Y < 0.95] = 0.95/2 = 0.475.
b) For this question, we need to find the probability that the smallest value of Y, denoted by Y(n), is less than 1.9. Since the Y's are independent and identically distributed, the probability of Y(n) being less than 1.9 is equal to 1 - the probability that all Y's are greater than or equal to 1.9.
So, we can write P[Y(n) < 1.9] = 1 - P[Y(1) >= 1.9, ..., Y(100) >= 1.9]. Since the Y's are independent, we can use the fact that the probability of the intersection of independent events is the product of their probabilities, and rewrite this as:
P[Y(n) < 1.9] = 1 - P[Y >= 1.9]^100
Now, we know that P[Y >= 1.9] is equal to the length of the interval (1.9, 2) divided by the length of the entire interval (0, 2), which is 0.1/2 = 0.05. Therefore, we have:
P[Y(n) < 1.9] = 1 - (0.05)^100
Using a calculator, we can find that P[Y(n) < 1.9] is approximately equal to 0.994.
