F(g(x)) where you see an 'x' in f(x) put a g:

f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!

I let the second one for you. Sorry if you disagree!

13.) The heights (in inches) of males in the United States are believed to be approximately normally

Fantom [35]

Answer:

Option C) 0.830

Step-by-step explanation:

We are given the following in the question:

The heights (in inches) of males in the United States are believed to be approximately normally distributed with mean $\mu$ .

Sample size, n = 25

Sample mean, $\bar{x}$ = 69.72 inches

Standard deviation, $\sigma$ = 4.15 inches

We have to find the standard error of $\bar{x}$ .

Standard error =

$\dfrac{\sigma}{\sqrt{n}} = \dfrac{4.15}{\sqrt{25}} = \dfrac{4.15}{5} = 0.83$

Thus, the standard error of $\bar{x}$ is 0.83 inches.

The correct answer is

Option C) 0.830

What is the solution to the equation below? √2x/√x-1=2 A. 4 B. 2 C. 5 D.3

nikdorinn [45]

Given:

The given equation is:

$\dfrac{\sqrt{2x}}{\sqrt{x-1}}=2$

To find:

The solution for the given equation.

Solution:

We have,

$\dfrac{\sqrt{2x}}{\sqrt{x-1}}=2$

On simplification, we get

$\sqrt{2x}=2\sqrt{x-1}$

Squaring both sides, we get

$2x=4(x-1)$

$2x=4x-4$

$2x-4x=-4$

$-2x=-4$

Divide both sides by -2.

$x=\dfrac{-4}{-2}$

$x=2$

Therefore, the correct option is B.
