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
Is "ab" an angle? If so, can you try to repost the picture because I cannot see anything so it's hard to try and help you.

Answer:
D ( x -2i sqrt(2)) ( x+ 2i sqrt(2))
Step-by-step explanation:
x^2 + 8
We want to factor so rewrite as squares
x^2 + (2sqrt(2))^2
Rewrite with a subtraction sign i^2 = -1
x^2 - (2*i*sqrt(2))^2
This is the difference of squares
a^2 - b^2 = ( a-b) (a+b)
( x -2i sqrt(2)) ( x+ 2i sqrt(2))
no it not a standard form
