According to the probability, the expected profit from playing this game is -$0.46 (option b).

If the chosen number appears on two of the dice, the player wins $6, and this outcome has a probability of 15/216. There are 15 ways in which the chosen number can appear on two of the dice (6 ways to choose the two dice, and 1 way for the remaining dice to not have the chosen number).

Finally, if the chosen number appears on all three dice, the player wins $12, and this outcome has a probability of 1/216, as there is only one way in which the chosen number can appear on all three dice.

To calculate the expected profit from playing this game, we need to multiply the profit from each outcome by its probability and sum up the results. Using the given distribution, we get:

Expected profit = (-$4 x 125/216) + ($4 x 75/216) + ($6 x 15/216) + ($12 x 1/216)

Expected profit = -$0.46

Therefore, the answer is option b: -$0.46.

The specific average rate of change, you need the temperature values and the corresponding time intervals during which the temperature is decreasing or increasing.

Average rate of change during a decreasing interval:

If the temperature is decreasing over an interval, you need two temperature values: the temperature at the beginning of the interval (T1) and the temperature at the end of the interval (T2). The average rate of change can be calculated using the formula:

Average rate of change = (T2 - T1) / (time interval)

Here, "time interval" represents the duration of the interval during which the temperature is decreasing. The result will be a negative value since the temperature is decreasing.

Average rate of change during an increasing interval:

If the temperature is increasing over an interval, you again need two temperature values: the temperature at the beginning of the interval (T1) and the temperature at the end of the interval (T2). The average rate of change can be calculated using the same formula:

Average rate of change = (T2 - T1) / (time interval)

In this case, the result will be a positive value since the temperature is increasing.

The length of the curve is l = ∫80(1+3(y-9)/(32y))^(1/2) dy

To find the length of the curve, we use the formula:

l = ∫a^b [(1 + [f'(x)]^2)^(1/2)] dx

In this case, we are given the equation for y in terms of x, so we need to find y' to use in the formula.

Starting with x = y√3(y-9)/(32y1/2), we can rearrange to solve for y in terms of x:

y = x^2 / [3(x^2/9 + 1)]

Next, we find the derivative of y with respect to x:

y' = [6x / (9x^2 + 27)] - [2x^3 / (9x^2 + 27)^(3/2)]

Simplifying:

y' = 6x / [9(x^2 + 3)] - 2x^3 / [9(x^2 + 3)^(3/2)]

Now we can substitute y' into the formula for l:

l = ∫0^8 [(1 + [6x / (9(x^2 + 3)) - 2x^3 / (9(x^2 + 3)^(3/2))]^2)^(1/2)] dx

Simplifying:

l = ∫0^8 [(1 + 9(x-9)^2 / (32x^2))^(1/2)] dx

To make the integral easier to solve, we can substitute u = 1 + 9(x-9)^2 / (32x^2), which gives:

l = ∫1.5^5.5 [2/3 * u^(1/2) * (u - 1)^(1/2) / (9(u-1) + 8(u-1)^(3/2))] du

Using integration by substitution and partial fractions, we can solve for l:

l = 16/27 [ (13/16)^{3/2} - (5/16)^{3/2} + 2(13/16)^{1/2} - 2(5/16)^{1/2} ]

There is not sufficient evidence to conclude that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased.

To determine if there is sufficient evidence that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased, we can use a hypothesis test.

Let p be the true proportion of families who eat dinner together seven nights a week. Our null hypothesis is that there has been no decrease in the proportion of families who eat dinner together seven nights a week:

H0: p = 0.32

Our alternative hypothesis is that the proportion has decreased:

Ha: p < 0.32

We will use a one-tailed z-test with an alpha level of 0.01.

First, we need to calculate the sample proportion, P:

P = 325/1089 ≈ 0.298

Next, we can calculate the test statistic, z0:

z0 = (P - p) / sqrt(p(1-p)/n)

where n is the sample size.

z0 = (0.298 - 0.32) / sqrt(0.32(1-0.32)/1089) ≈ -2.32

Finally, we can compare the test statistic to the critical value for a one-tailed z-test at an alpha level of 0.01. The critical value is -2.33. Since -2.32 is greater than -2.33, we fail to reject the null hypothesis.

Therefore, there is not sufficient evidence to conclude that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased.

In the direct variation equation y = kx, k represents the proportionality constant. Similar to this, in the inverse variation equation y = kx, k is the constant of variation.

A ratio called a constant of variation (k) shows how the independent variable (x) and the dependent variable are related to one another (y). If both of those variables have known values, you can find it by dividing y by x.

In order to obtain k given any position, we must divide the y-coordinate by the x-coordinate because k is constant (the same for every point). For instance, the variation constant is k = 3 if y changes straight as x and y = 6 when x = 2.

Step-by-step explanation:

The largest value of n for which function f(n) could be computed in one second is approximately 2.8 million. The largest value of n is 31,623. The largest value of n is 30.

If calculating f(n) takes nlog₂(n) big operations, and each bit operation is completed in \(10^{-9}\) seconds, we can calculate the largest value of n that can be computed in one second.

Let's set up the equation:

nlog₂(n) * \(10^{-9}\) seconds = 1 second

Simplifying the equation:

nlog₂(n) =  \(10^{-9}\)

To approximate the largest value of n, we can use trial and error or numerical methods. By trying different values of n, we can find that when n is around 2.8 million, the left-hand side of the equation is close to  \(10^{-9}\) .

Therefore, the largest value of n for which f(n) could be computed in one second is approximately 2.8 million.

If calculating f(n) takes n² big operations, and each bit operation is completed in  \(10^{-9}\)  seconds, we can calculate the largest value of n that can be computed in one second.

Let's set up the equation:

n² * \(10^{-9}\) seconds = 1 second

Simplifying the equation:

n² =  \(10^{-9}\)

Taking the square root of both sides:

n = √ \(10^{9}\)

Calculating the value:

n ≈ 31622.7766

Therefore, the largest value of n for which f(n) could be computed in one second is approximately 31,623.

If calculating f(n) takes \(2^{n}\) bit operations, and each bit operation is completed in  \(10^{-9}\)  seconds, we can calculate the largest value of n that can be computed in one second.

Let's set up the equation:

\(2^{n}\) *  \(10^{-9}\)  seconds = 1 second

Simplifying the equation:

\(2^{n}\) =  \(10^{9}\)

Taking the logarithm base 2 of both sides:

n = log₂( \(10^{9}\) )

Calculating the value:

n ≈ 29.897

Rounding to the nearest whole number:

n ≈ 30

Therefore, the largest value of n for which f(n) could be computed in one second is approximately 30.
