The mean difference in game scores over the six games is 12

The mean difference, or difference in means, measures the absolute difference between the mean value in two different groups.

Given the points by which a basketball team either won or lost 6 games.

- Won by 7 points = +7

- Lost by 10 points = -10

- Won by 8 points = +8

- Won by 11 points = +11

- Lost by 2 points = -2

- Won by 10 points = +10

Thus;

Mean difference of the 6 games is;

= (+7 - 10 + 8 + 11 - 2 + 10)/6

= 24/6

= 12

Hence, the mean difference in game scores over the six games is 12

The inverse of the cube root function used to act for the situation in model is f⁻¹(x) = √x³ - 4

Inverse of the cube root function f(x)

f(x) = ∛ (x + 4) ²

To find the inverse function, let f(x) = y

So, y = ∛ (x + 4) ²

Taking the cube of both sides, we have

y³ = [∛ (x + 4) ²] ³

y³ = (x + 4) ²

Taking square root of both sides, we have

√y³ = √ (x + 4) ²

√y³ = (x + 4)

Subtracting 4 from both sides, we have

√y³ - 4 = x + 4 - 4

√y³ - 4 = x

change y with x, we have

√x³ - 4 = y

Replacing y with f⁻¹(x), we have

The x-intercept of the composition is x = -1/2.

Remember that a linear function can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If a liear function passes through two points (x₁, y₁) and (x₂, y₂), then the  slope is:

a = (y₂ - y₁)/(x₂ - x₁)

For g(x) we can use (-1, 2) and (1, 6), the slope is:

a = (6 - 2)/(1 + 1) = 2

Then the function is something like:

g(x)=  2x + b

To find the value of b, we use again the point (1, 6)

g(1) = 6 = 2*1 + b

      6 - 2 = b

         4 = b

So:

g(x) = 2x + 4

Now the same for h(x), we can use the points (-1, -1) and (1, 7), we will get:

a = (7 + 1)/(1 + 1) = 4

h(x) = 4x + b

Using the point (1, 7)

h(1) = 7 = 4*1 + b

        7 - 4 = b

        3 = b

h(x) = 4x + 3

The composition is:

g( h(x)) = 2*h(x) + 4

           = 2*(4x + 3) + 4

We have,

y =

The equation represents exponential growth because the growth factor is greater than 1.

The general form equation is:

The following entropies are evaluated as H(X, Y ) = ∑p(x, y) log p(x, y), H(X|Y ) = ∑p(x, y) log p(x|y) = −E[ log(p(x|y)) .

We have the following joint probability distribution:

X/Y  0   1

0    1/3   1/3

1      0    1/3

The entropy of X is given by

H(X) = −p log p − (1 − p) log(1 − p) = H(p)

The entropy does not depend on the values that the random variable takes (0 and 1 in this case), but only depends on the probability distribution p(x).

The joint entropy is given by

H(X, Y ) = ∑p(x, y) log p(x, y).

The joint entropy measures how much uncertainty there is in the two random variables X and Y

taken together.

The conditional entropy of X given Y is

H(X|Y ) = ∑p(x, y) log p(x|y) = −E[ log(p(x|y))

The conditional entropy is a measure of how much uncertainty remains about the random variable

X when we know the value of Y.

For two variables, the chain rule becomes:

H(X, Y ) = H(X|Y ) + H(Y ) = = H(Y |X) + H(X).

Thus, the following entropies are evaluated as H(X, Y ) = ∑p(x, y) log p(x, y), H(X|Y ) = ∑p(x, y) log p(x|y) = −E[ log(p(x|y)) .

Answer:

After 17,190 years, the amount of carbon-14 left would be approximately 5 mg.

The half-life of carbon-14 is 5,730 years, which means that every 5,730 years, half of the remaining carbon-14 decays. To calculate the amount of carbon-14 remaining after 17,190 years, we can use the formula:

A = A0 * (1/2)^(t/T)

where:

A0 is the initial amount (80 mg)

t is the time elapsed (17,190 years)

T is the half-life (5,730 years)

A = 80 * (1/2)^(17,190/5,730)

A = 80 * (1/2)^3

A = 80 * (1/8)

A = 10 mg * 1/2

A = 5 mg

So you use 73.02 minutes of talk time each month.

Cell phone is a portable electronic device that allows you to make calls, send messages, and perform various tasks such as browsing the internet.

Let x be the number of minutes of talk time you use each month.

The cost for the talk time each month is 19.80 + 0.09(x - 500), and the cost for e-mail is 0.2 * 19.80 = 3.96.

So, the total cost each month is 19.80 + 0.09(x - 500) + 3.96 = 23.76 + 0.09x - 46.04.

The total cost for 7 months is 7 * (23.76 + 0.09x - 46.04) = 166.32 + 0.63x.

We want to find the value of x that makes the total cost equal to $212.31, so we write:

166.32 + 0.63x = 212.31

Solving for x, we have:

0.63x = 45.99

x = 73.02

So you use 73.02 minutes of talk time each month
