Answer:
Candace has $57.5 and Amar has $37.5.
Step-by-step explanation:
x+(x+20)=z
x+20=y
x+y=z
--------------
2x+20=95
2x=95-20
2x=75
x=75/2
x=37.5
37.5+20=y=57.5

Step-by-step explanation:
Hello!
Recall that:
can be rewritten as:
Use the equation for the derivative of a log expression:
Substitute in the values in the expression:
The 68 - 95 - 99.7 rule, gives the basis to solve this question.
It says that for a normal distribution 95% of the results are between the mean minus 2 standard deviations and the mean plus 2 standard deviations.
Here:
mean = 64.5 inches,
standard deviaton = 2.5 inches
mean - 2 standard deviations = 64.5 inches - 5 inches = 59.5 inches
mean + 2 standard deviations = 64.5 inches + 5 inches = 69.5 inches
Then, the answer is that 95% of women range approximately between 59.5 inches and 69.5 inches.
