The length of a swimming pool is 22 ft. The width is 40 ft. If the volume of the pool is 2,500 m3, what equation shows you how y

Alexeev081 [22]

Answer:

volume= length x width x height

Step-by-step explanation:

In this instance the height will represent the depth of the pool.

To actually solve it it would look like

2500=(22)(40)(h)

2500=880(h)

2.84=h (or depth)

Suppose the number of residents within five miles of each of your stores is asymmetrically distributed with a mean of 25 thousan

ohaa [14]

Answer:

$P(\bar X\:>27.8\:thousand)=3.07\%$

Step-by-step explanation:

Since the number of residents within five miles of each of your stores is asymmetrically distributed, the distribution of the sample means will be approximately normal with a mean of 25 thousand.

The standard deviation of the sample means is:

$\sigma_X=\frac{\sigma}{\sqrt{n} }$

$\implies \sigma_X=\frac{10.6}{\sqrt{50} }=1.4991$

The z value is $z=\frac{\bar X-\mu}{\frac{\sigma}{\sqrt{n}} }$

We plug in the values to get:

$z=\frac{27.8-25}{1.4991}=\frac{2.8}{1.4991}=1.87$

The area to the right of 1.87 is $1-0.96926=0.03074$ .

The probability that the average number of residents within five miles of each store in a sample of 50 stores will be more than 27.8 thousand is 3.07%
