Answer: 0.0062
Step-by-step explanation:
Given : Mean : 
Standard deviation :
Sample size : 
Assume that age of people in the country is normally distributed.
The formula to calculate the z-score :-

For x = 32

The p-value = 

Hence, the the probability that the average age of our sample is at least =0.0062
Lets analyze the equation:
<span>ax^2 - bx = 0
</span>x(ax - b) = <span>0
</span>Therefore if x = 0, the equation holds no <span>matter about a and b</span>:
0(0a - b) = 0
0 = 0
Formula for Compound Interest
Amount = Principal * (1 + Rate/100)^Time
A = P * (1 + R/100)^T
P = A/((1 + R/100)^T) = 92000/((1 + 4.7/100)^16) = $44120.5503
The answer is 80 because 400 divided by 5 is 80
