Let X denote daily work hours. Suppose that for the sample of workers you have, the average daily work hours are 8 hours, with

Answer:

The mean for Z is 40.

The standard deviation for Z is 25.

Step-by-step explanation:

We are given the following in the question:

X: daily work hours.

The average daily work hours are 8 hours, with a standard deviation of 5.

$E(x) = 8\\S.D(X) = 5$

$Var(X) = 5^2 = 25$

Z denote weekly work hours.

We have to find the mean and standard deviation for Z.

$E(Z) =E(5x) = 5\tims E(X) = 5\times 8 = 40$

The mean for Z is 40.

We use the property:

$Var(ax) = a^2Var(x)$

$Var(Z) = Var(5x) = 5^2(Var(X)) = 25\times 25 = 625\\S.D(Z) = \sqrt{625} = 25$

Thus, the standard deviation for Z is 25.

Step-by-step explanation:

the average rate of change is

(f(x2) - f(x1)) / (x2 - x1)

so, for x = 1 and 2

(4×3² - 4×3¹) / (2 - 1) = 36 - 12 = 24

for x = 3 and 4

(4×3⁴ - 4×3³) / (4 - 3) = 324 - 108 = 216

so the second rate is 216/24 = 9 times greater than the first rate.

What is the value of A when we rewrite (32/5)^-2x as A^x

defon

Answer:

$(\dfrac{25}{1024})^x$

Step-by-step explanation:

The given expression is :

$(\dfrac{32}{5})^{-2x}$

We need to rewrite it in the form of $A^x$ .

We know that, $(\dfrac{1}{x})^{-a}=x^a$

So,

$(\dfrac{32}{5})^{-2x}=(\dfrac{5}{32})^{2x}\\\\=(\dfrac{5^2}{32^2})^x\\\\=(\dfrac{25}{1024})^x$

So, $A=\dfrac{25}{1024}$ . Hence, this is the required solution.
