The number of orders received daily by an online vendor of used CDs is normally distributed with mean 270 and standard deviation
frez [133]

Answer:

Step-by-step explanation:

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 bus gets off the freeway, stops at a rest stop for passengers to get lunch, and then gets back on the freeway.
lozanna [386]
I believe the first graph in the shape of the \_/ is the correct graph because when he gets off the freeway his speed slows then he stops and is no longer moving for a period of time. Then he gets back on and his speed is going up.
