The critical number is also x = 4.To find the critical number(s) of a function, we need to first take the derivative of the function and then find where the derivative is equal to zero or undefined.

4. F(x) = x-1/x^2-x+2

To find the derivative, we can use the quotient rule:

F'(x) = [(x^2-x+2)(1) - (x-1)(2x-1)] / (x^2-x+2)^2

Next, we need to find where F'(x) is equal to zero or undefined.

Setting the numerator equal to zero gives:

(x^2-x+2) - (2x^2-3x+1) = 0

-x^2 + 4x - 1 = 0

Using the quadratic formula, we can solve for x:

x = (4 ± sqrt(16-4(-1)(-1))) / (-2)

x = (4 ± sqrt(20)) / (-2)

x = 1 ± sqrt(5)

So the critical numbers are 1 + sqrt(5) and 1 - sqrt(5).

5. F(x) = x^3/4 – 2x^1/4

To find the derivative, we can use the power rule:

F'(x) = (3/4)x^-1/4 - (1/2)x^-3/4

Next, we need to find where F'(x) is equal to zero or undefined.

Setting the numerator equal to zero gives:

3x^-1/4 - 2x^-3/4 = 0

Multiplying both sides by x^3/4 gives:

3 - 2x = 0

Solving for x gives:

x = 3/2

So the critical number is 3/2.

6. F(x) = x^4/5(x-4)^2

To find the derivative, we can use the quotient rule:

F'(x) = [(x-4)^2(4x^3/5) - x^4/5(2(x-4)(1))] / (x-4)^4

Simplifying gives:

F'(x) = (2x^3 + 16x^2 - 32x) / 5(x-4)^3

Next, we need to find where F'(x) is equal to zero or undefined.

Setting the numerator equal to zero gives:

2x(x^2 + 8x - 16) = 0

Using the quadratic formula, we can solve for x:

x = (-8 ± sqrt(64 + 8(16))) / 2

x = (-8 ± sqrt(192)) / 2

x = -4 ± 2sqrt(6)

So the critical numbers are -4 + 2sqrt(6) and -4 - 2sqrt(6). However, we also need to check if the derivative is undefined at x = 4.

Plugging in x = 4 gives:

F'(4) = (2(4)^3 + 16(4)^2 - 32(4)) / 5(4-4)^3

F'(4) = undefined

So the critical number is also x = 4.

Thus, the probability is 1/100 or 0.01, which means there is a 1% chance of getting a triple-digit number with all the same digits in this lottery game.

To calculate the probability of getting a triple-digit number where all digits are the same in a lottery game that consists of selecting a three-digit number, you should first determine the number of favorable outcomes and the total possible outcomes.

There are 9 favorable outcomes, as the triple-digit numbers with the same digits are: 111, 222, 333, 444, 555, 666, 777, 888, and 999. Note that we don't include 000 since it's not a triple-digit number.

Now, let's find the total possible outcomes. In a three-digit number, there are 10 possible digits (0-9) for each of the three positions. However, the first position cannot be 0, as that would not be a triple-digit number.

So, there are 9 possible digits for the first position and 10 for the other two. The total possible outcomes are 9 x 10 x 10, which equals 900.

Finally, to find the probability of getting a triple-digit number with all the same digits, divide the number of favorable outcomes by the total possible outcomes:

Probability = Favorable Outcomes / Total Possible Outcomes
Probability = 9 / 900

The probability is 1/100 or 0.01, which means there is a 1% chance of getting a triple-digit number with all the same digits in this lottery game.

The probability that the sample proportion will differ from the population proportion by less than 0.03 is 62%

To calculate the probability that the sample proportion will differ from the population proportion by less than 0.03, we first need to calculate the standard error of the sample proportion. The formula for the standard error is:

SE = [tex]\sqrt{[p(1-p)/n]}[/tex]

Where p is the population proportion (0.04), and n is the sample size (238). Plugging in these values, we get:

SE = [tex]\sqrt{[0.04(1-0.04)/238]}[/tex] = 0.028

Next, we need to calculate the margin of error, which is given by:

ME = z*SE

Where z is the z-score that corresponds to the desired level of confidence. Let's assume we want a 95% confidence level, which corresponds to a z-score of 1.96. Plugging in these values, we get:

ME = 1.96*0.028 = 0.055

Finally, we can calculate the probability that the sample proportion will differ from the population proportion by less than 0.03 by subtracting the margin of error from both sides of the true proportion (0.04) and adding it back on:

0.04 - 0.055 < p < 0.04 + 0.055

Simplifying, we get:

-0.015 < p - 0.04 < 0.015

Dividing by the standard error, we get:

-0.535 < z < 0.535

Looking up these z-scores in a standard normal distribution table, we find that the probability of getting a sample proportion within 0.03 of the population proportion is approximately 0.62, or 62%. This means that there is a 62% chance that the sample proportion will be within 0.03 of the population proportion if we were to sample 238 people from the city.

Moses is currently 3996 years old.

Let's denote Methuselah's current age as "M" and Moses's current age as "M2".

"Moses is twice as old as Methuselah was when Methuselah was one-third as old as Moses will be when Moses is as old as Methuselah is now." This can be written as:

M2 = 2 × (M - (1/3) × M2)

We can simplify this equation by multiplying both sides by 3:

3 × M2 = 6 × (M - (1/3) × M2)

3 × M2 = 6M - 2 × M2

5 × M2 = 6M

"If the difference of their ages is 666" can be written as:

M2 - M = 666

We can use equation (5) to substitute for M2 in equation (6):

5 × M2 = 6M

5 × (M + 666) = 6M

5M + 3330 = 6M

M = 3330

Therefore, Methuselah is currently 3330 years old. We can use equation (6) to find Moses's current age:

The time between buses is 10 minutes and the bus waits at the station for 3 minutes, so the time between the departure of one bus and the departure of the next bus is 10 + 3 = 13 minutes.

Since you arrive at a random time, the time you have to wait for the next bus can be any number from 0 to 13 minutes, with each value between 0 and 13 being equally likely.

The probability that you will have to wait more than 6 minutes to board a bus is the probability that you arrive at the station between 0 and 7 minutes after a bus has left.

This is because if you arrive at the station more than 7 minutes after a bus has left, you will have to wait less than 6 minutes for the next bus to arrival time.

The probability that you arrive at the station between 0 and 7 minutes after a bus has left is 7/13, or approximately 0.538.

The critical numbers are 0 and 2, and the behavior of f at these numbers is At x = 0, the function has a local minimum.
At x = 2, the function has neither a local maximum nor a local minimum.

To find the critical numbers, we need to take the derivative of the function and set it equal to zero:
f'(x) = 6x^5(x-2)^5 + x^6(5)(x-2)^4(1) = 0
Simplifying this equation, we get:
x(x-2)^4(6x^4 + 5x^2(x-2)) = 0
The critical numbers are where the derivative equals zero, which are x = 0 and x = 2.
To describe the behavior of f at these critical numbers, we need to examine the sign of the derivative around each critical number. If the derivative is positive to the left and negative to the right of a critical number, then the function has a local maximum at that point. If the derivative is negative to the left and positive to the right, then the function has a local minimum at that point. If the derivative does not change sign at a critical number, then the function has neither a local maximum nor a local minimum at that point.
Let's examine each critical number:
At x = 0, we can see that the factor x is negative to the left of 0 and positive to the right of 0. The factor (x-2)^4 is positive everywhere. The factor 6x^4 + 5x^2(x-2) is positive at x = 0 (since the x^2 term is zero), which means the derivative is positive to the left and right of x = 0. Therefore, f has a local minimum at x = 0.
At x = 2, we can see that the factor (x-2)^4 is zero at x = 2, which means the derivative is zero at x = 2. To determine whether f has a local maximum or minimum at x = 2, we need to examine the sign of the derivative on either side of 2. If we plug in a value slightly less than 2 (e.g. x = 1.9), we get a positive derivative. If we plug in a value slightly greater than 2 (e.g. x = 2.1), we also get a positive derivative. Therefore, f has neither a local maximum nor a local minimum at x = 2.

To indicate the direction in which the curve is traced as the parameter increases, we can draw an arrow that points from lower left to upper right, since the curve moves from the point (1, 1) at t = 0 to the right and upward as t increases.

To eliminate the parameter, we can use the fact that x = e^t and y = e^(-3t) to solve for t in terms of x and y. Taking the natural logarithm of both sides of x = e^t, we get ln(x) = t. Similarly, taking the natural logarithm of both sides of y = e^(-3t), we get ln(y) = -3t, or t = (-1/3)ln(y). Substituting this expression for t into the equation we found for ln(x), we get ln(x) = (-1/3)ln(y), which simplifies to ln(x^3) = ln(y^(-1)), or x^3 = 1/y. This is the Cartesian equation of the curve.

To sketch the curve, we can start by noting that both x and y are positive for all values of t, since e^t and e^(-3t) are always positive. As t increases, x and y both increase, but y increases much more slowly than x since e^(-3t) decreases rapidly as t increases. This means that the curve starts out very steep (since the slope of the tangent line at t = 0 is dx/dt = 1 and dy/dt = -3), but becomes flatter and flatter as t increases. The curve approaches the x-axis as t approaches infinity, but never touches it.

(a) To find E(Ti2), we can use the fact that the interarrival times of a Poisson process are exponentially distributed. Since T2 is the time of the second arrival,

We can write T2 = T1 + X, where X is the time between the first and second arrivals. Thus, we have:

E(T2) = E(T1 + X) = E(T1) + E(X)

Since the Poisson process has rate 3, the interarrival times are exponentially distributed with parameter λ = 3. Therefore, we have E(X) = 1/λ = 1/3. Also, the time of the first arrival is distributed as an exponential random variable with parameter λ, so we have E(T1) = 1/λ = 1/3. Putting it all together, we get:

E(T2) = E(T1) + E(X) = 1/3 + 1/3 = 2/3

Therefore, E(Ti2) = 2/3.

(b) To find E(Tiz/N(2) = 5), we need to condition on the value of N(2). We have:

E(Ti2/N(2) = 5) = ∑k≥2 E(Ti2/N(2) = 5, N(2) = k) P(N(2) = k)

Since the Poisson process has independent and stationary increments, we know that the distribution of N(2) is Poisson with parameter 6. Therefore, we have:

P(N(2) = k) = e^(-6) 6^k / k!

For a fixed value of N(2) = k, we can think of the process up to time T2 as a Poisson process with rate 3, and condition on the times of the first k arrivals. The time of the ith arrival, given the times of the first i-1 arrivals, is distributed as an exponential random variable with parameter λ = 3. Therefore, we have:

E(Ti2/N(2) = 5, N(2) = k) = E(Ti2 | T1, T2, ..., Tk)

Using the memoryless property of the exponential distribution, we can write:

E(Ti2 | T1, T2, ..., Ti-1) = Ti + E(T2 | T1, T2, ..., Ti-1) = Ti + 2/3

Therefore, we have:

E(Ti2/N(2) = 5, N(2) = k) = Ti + 2/3

Putting it all together, we get:

E(Tiz/N(2) = 5) = ∑k≥2 ∑i≥1 (Ti + 2/3) e^(-6) 6^k / k!

Using the fact that the interarrival times are exponentially distributed, we can compute the sum over i as:

∑i≥1 (Ti + 2/3) = E(T2) + 2/3 = 8/3

Therefore, we have:

E(Tiz/N(2) = 5) = (8/3) ∑k≥2 e^(-6) 6^k / k! = (8/3) (1 - e^(-12))

Thus, E(Tiz/N(2) = 5) ≈ 1.81.

(c) To find E(N(S) N(2) = 5), we can use the fact that the number of arrivals in a Poisson process of rate λ in an interval of length t is a Poisson random variable with parameter λt. Therefore, we have:

E(N(S) N(2) = 5) = E(N(5) N(2) = 5) = E(N(5)^2 | N(2) = 5) P(N(2) = 5)

For a fixed value of N(2) = 5, we can think of the process up to time 5 as a Poisson process with rate 3, and condition on the times of the first 5 arrivals. Therefore, we have:

E(N(5)^2 | N(2) = 5) = E((N(5) - 5)^2 | N(2) = 5) + E(10 N(5) - 25 | N(2) = 5) + 25

Using the fact that the number of arrivals in an interval of length t is Poisson with parameter λt, we have:

E((N(5) - 5)^2 | N(2) = 5) = Var(N(3)) = 3

Also, we have:

E(10 N(5) - 25 | N(2) = 5) = 10 E(N(5) | N(2) = 5) - 25 = 10 (5 + 2) - 25 = 15

Putting it all together, we get:

E(N(S) N(2) = 5) = (3 + 15 + 25) P(N(2) = 5) = 43 e^(-6) 6^5 / 5!

Thus, E(N(S) N(2) = 5) ≈ 1.94.

Answer:13/24

Step-by-step explanation 1. the desired probability is the sum of the probabilities of two disjoint events. In the first event, an apple is selected from the first basket and an orange is selected from the second basket; the probability of this event is (4/6)(5/8)=20/48.                                                           2. In the second event, an orange is selected from the first basket and an apple is selected from the second basket; the probability of this event is (2/6)(3/8)=6/48. Therefore, the desired probability is 20/48+6/48=26/48=13/24.

The researcher is trying to reduce the cause of within-group variance related to individual differences or heterogeneity within the sample.

In statistics, within-group variance, also known as within-group variation or error variance, refers to the variability of data within a specific group or sample. It represents the differences among individuals within the same group or sample.

There are several causes of within-group variance, such as individual differences, measurement error, and uncontrolled extraneous variables.

In this scenario, the researcher is trying to limit who the findings will generalize to, which means that she wants to control or reduce the effect of individual differences or heterogeneity within the sample.

By limiting the sample to a specific population or subgroup, the researcher can reduce the within-group variance related to individual differences and increase the likelihood of finding significant results.

The distance of the losing shot from the center is also uniformly distributed from 0 to 1.  To find the PDF of the distance of the losing shot from the center, we need to first determine the probability of one shot being closer to the center than the other.

Let X be the distance of the first shot from the center, and Y be the distance of the second shot from the center. Then, the probability that X is closer to the center than Y is given by the area of the region where X < Y, which is a triangular region with base 1 and height 1/2 (since the probability of X being closer to the center than Y is the same as the probability of Y being closer to the center than X). Therefore, the probability of X being closer to the center than Y is 1/4.

Now, let Z be the distance of the losing shot from the center. We know that Z is equal to the distance of the second shot from the center if the second shot is closer to the center than the first shot, and it is equal to the distance of the first shot from the center if the first shot is closer to the center than the second shot. Therefore, the PDF of Z is given by:

fZ(z) = (1/4)fY(z) + (3/4)fX(z)

where fX(x) and fY(y) are the PDFs of X and Y, respectively. Since X and Y are uniformly distributed from 0 to 1, their PDFs are both equal to 1 for 0 ≤ x ≤ 1 and 0 ≤ y ≤ 1. Therefore, we have:

fZ(z) = (1/4) + (3/4) = 1

for 0 ≤ z ≤ 1. This means that the distance of the losing shot from the center is also uniformly distributed from 0 to 1.

The foci of the ellipse are (4, 0) and (9, 0).

To find the foci of the ellipse, we first need to determine its standard form equation and identify the values of the major and minor axes. Given the endpoints of the major axis are (0,0) and (13,0), we can determine that the length of the major axis (2a) is 13 units. Thus, a = 6.5 units.

The minor axis has a length of 12 units, so the length of the minor axis (2b) is 12 units. Therefore, b = 6 units.

Next, we will find the value of c, which is the distance from the center of the ellipse to each focus. Using the relationship [tex]c^2 = a^2 - b^2[/tex], we get:

[tex]c^2 = (6.5)^2 - (6)^2[/tex]
[tex]c^2 = 42.25 - 36[/tex]
[tex]c^2 = 6.25[/tex]
c = √6.25
c ≈ 2.5 units

Now, we have all the necessary information to find the foci of the ellipse. Since the major axis is along the x-axis, the foci will be located at a distance of c units to the left and right of the center (which is the midpoint of the major axis). The center of the ellipse is (6.5, 0), so the foci will be at (6.5 - 2.5, 0) and (6.5 + 2.5, 0), which are (4, 0) and (9, 0).

Answer:

$11.10

Step-by-step explanation:

To calculate the price of the sno-cone machine after discount and sales tax, we need to first calculate the discount and then add sales tax.

The sno-cone machine is priced at $13 and is on sale for 20% off. To calculate the discount, we can multiply the original price by the discount rate:

Discount = Original Price x Discount Rate

Discount = $13 x 0.20

Discount = $2.60

Therefore, the discount is $2.60.

The sale price of the sno-cone machine after discount can be calculated by subtracting the discount from the original price:

Sale Price = Original Price - Discount

Sale Price = $13 - $2.60

Sale Price = $10.40

Therefore, the sale price of the sno-cone machine after discount is $10.40.

To calculate the sales tax, we can multiply the sale price by the sales tax rate:

Sales Tax = Sale Price x Sales Tax Rate

Sales Tax = $10.40 x 0.0675

Sales Tax = $0.70

Therefore, the sales tax is $0.70.

Finally, to calculate the final price of the sno-cone machine after discount and sales tax, we can add the sale price and sales tax:

Final Price = Sale Price + Sales Tax

Final Price = $10.40 + $0.70

Final Price = $11.10

Therefore, the final price of the sno-cone machine after discount and sales tax is $11.10 1.

The amount of all angles within every quadrilateral adds up to a cumulative 360°.

All triangles exhibit angles that total 180°, and since the diagonal is shared between both of these triangles, we shall add up their angles only once when totaling the quadrilateral.

Consequently, the sum of all four angles in the quadrilateral is twice the angle degree of one triangle plus 180° (for the connecting diagonal), which equates to:

(180°) + 180° = 360°

Therefore, the amount of all angles within every quadrilateral adds up to a cumulative 360°.

This justification holds true for all types of quadrilaterals, for instance the one illustrated in the representation at the right, due to it being divided into two parts through the extention of a diagonal.

There are 888 employees on The Game Shop's sales team. Last month, they sold a total of ggg games. Chris sold 171717 fewer games than the team averaged per employee, so the number of games he sold can be expressed as: (ggg/888) - 171717.

To find the average number of games sold per employee, we divide the total number of games sold by the total number of employees.

The problem gives us the total number of employees, which is 888, and the total number of games sold, which is ggg. So, the average number of games sold per employee is:

ggg games ÷ 888 employees = ggg/888 games per employee

Next, we're told that Chris sold 171717 fewer games than the team averaged per employee.

This means that the number of games he sold is equal to the average number of games sold per employee minus 171717.

Thus, the expression for the number of games Chris sold is: (ggg/888) - 171717.
