For the distribution of GPAs described in problem 1, what is the probability that a randomly selected student will have a GPA Z score Probability a. less than 3.40 b. less than 3.78 c. more than 3.50 d. more than 2.50 e. between 2.00 and 3.00 f. between 3.00 and 3.50

.25

step-by-step explanation:

x = 12

y = 1

for the points!

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
