Hello!

This question is an example of function composition.

Given, f(x) = 3x - 5, find f(x - 1). For this problem, we substitute x for (x - 1).

f(x - 1) = 3(x - 1) - 5

f(x - 1) = 3x - 3 - 5

f(x - 1) = 3x - 8

Therefore, the answer is choice D, f(x - 1) = 3x - 8.

Answer:

$n=35$

Step-by-step explanation:

From the question we are told that:

Standard Deviation $\sigma=4min$

Let

$CI=95\%$

Since

Significance level $\alpha$

$\alpha =1-CI$

$\alpha =1-0.95$

Therefore

$Z_{\alpha/2}=Z_{0.025$

$Z_{\alpha/2}}=1.96$

Generally the equation for Sample size is mathematically given by

$n = (Z_{\alpha/2}* \frac{\sigma}{E})^2$

$n= \frac{1.96 * 3}{1}^2$

$n=35$
