Given that the number of orders received daily by an online vendor of used CDs (say X) is normally distributed with mean 270 and standard deviation 16.

X is N(270, 16)

To find percentage of days will the company have to hire extra help or pay overtime, we can find probability using std normal table

X>302 means

$Z>\frac{302-270}{16} =2$

P(Z>2) = 0.25

Thus 25% of days will the company have to hire extra help or pay overtime

a rectangular computer screen has an area o A square inches. The width of the computer is 7 inches. Which equation rpresents x t

neonofarm [45]

Answer:

x = A/7

Step-by-step explanation:

Given that the screen is rectangular, recall that the area A of a rectangle whose length is L and width is W is given as

A = L * W

Hence if the width is 7 inches and the length is x inches then the area which is A square inches is connected to both sides as

A = x * 7

Divide both sides by 7

x = A/7 inches
