The surface area of a rectangular prism is measured by multiplying length, width, and height:

a = l•w•h

4 • 5 • 15

20 • 15 = 300

So the area of this rectangular prism is 300<span>in².</span>

g Water use in the summer is normally distributed with a mean of 310.4 million gallons per day and a standard deviation of 40 mi

andreev551 [17]

Answer: The value of b = 0.99

The probability that a day requires more water than is stored in city reservoirs is 0.161.

Step-by-step explanation:

Given : Water use in the summer is normally distributed with

$\mu=310.4\text{ million gallons per day}$

Standard deviation : $\sigma=40 \text{ million gallons per day}$

Let x be the combined storage capacity requires by the reservoir on a random day.

Z-score : $\dfrac{x-\mu}{\sigma}$

$z=\dfrac{350-310.4}{40}=0.99$

The probability that a day requires more water than is stored in city reservoirs is :

$P(x>350)=P(z>0.99)=1-P(z$

Hence, the probability that a day requires more water than is stored in city reservoirs is 0.161

The local library has a childern section with pictures books and chapter books the ratio is 2:3 id thete are a total of 500 book

Anvisha [2.4K]

Look at the ratio (2:3). You can see that the numbers of "ratio units" add up to 5, and that the total number of books is 100 times that value. Then each "ratio unit" stands for 100 books.

3 ratio units of chapter books mean there are 300 chapter books.
