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

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

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

$n=35$

Your family has a circular swimming pool. The radius of the pool is 9 feet and and its depth is 4 feet. What is the volume of th

-Dominant- [34]

Given

Your family has a circular swimming pool.

The radius of the pool is 9 feet and and its depth is 4 feet.

Find out the volume of the pool.

To proof

As depth is given in the question that means the shape of the swimming pool

is cylinder.

Formula

$Volume\ of\ cylinder = \pi r^{2}h$

where r = radius

h = height

now

radius of the pool is 9 feet and and its depth is 4 feet.

put all the values in the above equation

we get

$= \pi\times 9^{2}\times 4$

use 3.14 to approximate pi

$= 3.14\times 9\times9\times4$

we get

= 1017.4 ( approx )feet²

Hence proved

salantis [7]

Just multiply 30 times 2,000 and also multiply 30 times 700. The reason you will multiply it by 30 is because in 1 month there is 30 days. 30 x 2,000= 60000 30 x 700 = 21000 I’m only 9 btw so sorry if I didn’t give a lot of detail lol
