The probability that a day requires more water than is stored in city reservoirs is 0.161.
Step-by-step explanation:
Given : Water use in the summer is normally distributed with
Standard deviation : 
Let x be the combined storage capacity requires by the reservoir on a random day.
Z-score : 
The probability that a day requires more water than is stored in city reservoirs is :
Hence, the probability that a day requires more water than is stored in city reservoirs is 0.161

Answer: Angelo is 13 years old.
Aaron is 15 years old
Alfred is 34 years old
Step-by-step explanation:
Let x represent the age of Angelo.
Let y represent the age of Aaron.
Let z represent the age of Alfred
The sum of three guys ages is 62. It means that
x + y + z = 62 - - - - - - - - - - -1
Angelo is two years younger than Aaron. It means that
x = y - 2
Alfred is four years older than twice Aaron's age. It means that
z = 2y + 4
Substituting x = y - 2 and z = 2y + 4 into equation 1, it becomes
y - 2 + y + 2y + 4 = 62
4y + 2 = 62
4y = 62 - 2 = 60
y = 60/4 = 15
x = y - 2 = 15 - 2
x = 13
z = 2y + 4 = 2 × 15 + 4
z = 34
