SIZIF [17.4K]

The sampling distribution of the difference in sample means x⁻₁ - x⁻₂ is; 3.5 - 3.5 = 0

<h3>Difference in sample means</h3>

We are told that;

  • A fair six-sided die, with sides numbered 1 through 6, will be rolled a total of 15 times.
  • x⁻₁ represents the average of the first ten rolls.
  • x⁻₂ represents the average of the remaining five rolls.

Now, the average of the largest and lowest numbers of the six sided die is;

E(x) = (6 + 1)/2 = 3.5

Thus, the average mean of the first ten rows is expressed as;

E(x⁻₁) = (n * E(x))/n

E(x⁻₁) = (10 * 3.5)/10

E(x⁻₁) = 3.5

The average mean of the last five rolls will be;

E(x⁻₂) = (n * E(x))/n

E(x⁻₂) = (5 * 3.5)/5

E(x⁻₂) = 3.5

Thus;

x⁻₁ - x⁻₂ = 3.5 - 3.5 = 0

Graph a system of equations to approximate the value of x, the rate of depreciation. Give your answer as a percent. About 4% abo
Dovator [93]

Depreciation involves the reduction in the value of a quantity

The rate of depreciation is about 13%

<h3>How to determine the equation</h3>

From the question, we have the following ordered pairs

(x,y) = {(0,9000) and (5,4500)}

The depreciation equation is represented as:

y = ab^x

At (0,9000), we have:

ab^0 = 9000

a = 9000

At (5,4500), we have:

ab^5 = 4500

This gives

9000b^5 = 4500

Solve for b^5

b^5 = 0.5

Take the 5th roots

b = 0.87

So, we have:

y = ab^x

y = 9000(0.87)^x

The rate (r) is then calculated as:

1 -r = b

This gives

r =1 - b

r =1 - 0.87

r =0.13

Express as percentage

r= 13\%

Hence, the rate of depreciation is about 13%
