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

P(Z>2) = 0.25
Thus 25% of days will the company have to hire extra help or pay overtime
16
divide 12 by 3 since its 3/4 of the whole thing so 1/4=4
Volume of a cone = [(pi)r^2(h)]:3 = [3.14 (25m^2)(12m)]:3 = 314in^3.
B, I believe. But go with your gut instinct
