The volume v of a pyramid with a square base with side length s and height h is upper v equals one third s squared hv= 1 3s2h. s

zheka24 [161]

In this question,it is given that,

The volume v of a pyramid with a square base with side length s and height h is

$V = \frac{1}{3} s^2 h$

And we have to solve for s.

First we will get rid of 3 by multiplying both sides by 3, that is

$3V = s^2h
\\
s^2 = \frac{3V}{h}
\\ s = \sqrt{ \frac{3V}{h}}$

And in the next part it is given that , volume is 7700 cubic meters and height is 148 meters .

Substituting these values, we will get

$s = \sqrt{ \frac{3V}{h}}
\\
s = \sqrt{ \frac{3*7700}{148}} = 12.5 meters$

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

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

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

$n=35$
