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% :-
Answer:
0.85 m
Step-by-step explanation:
0.68/8=A decent of 0.085 miles per 0.1 minute
So per minute 0.085x10 =0.85, our plane will have a change of 0.85 m in altitude

The formula to this question is the amount of rows and how many fruit are in each row.
So 4x12=48
There are 48 apples in the apple orchard
and 6x15=90
so 90+48=138
There are 138 pieces of fruit in total
