Given that one standard deviation below the mean is 24 and one standard deviation above the mean is 31, what is the mean?
A)55
B)34
C) 27.5
D)28

the correct is answer is a 9-sided polygon!

i dont know the answer but here's a picture of a dog

step-by-step explanation:

for volume, add base x height x width

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
