Answer:
4.5 inches
Step-by-step explanation:
We are given the formula:
V =
Plug in the the radius (3) and volume (127.23):
127.23 =
Square the 3 :
127.23 =
Multiply the pi & volume:
127.23 = 28.26h
Divide both sides by 28.26:
127.23 ÷ 28.26 = 28.26h ÷ 28.26
h = 4.5021231...

Answer: 0.3974
Step-by-step explanation:
Given : The distribution of annual returns on common stocks is roughly symmetric, so the mean return over even a moderate number of years is close to Normal.
Real annual returns on U.S. common stocks had mean :
Standard deviation :
We assume that the past pattern of variation continues.
Let x be the random variable that represents the annual returns on common stocks over the next 32 years .
The formula for z-score :
For x= 0.14,
By using the standard normal distribution table , we have
The probability that the mean annual return on common stocks over the next 32 years will exceed 14% :-
