A sample of 200 students in Podunk university was taken after the midterm exam to ask them whether they went bar hopping the weekend before the midterm or spent the weekend studying, and whether they did well or poorly on the midterm. The following table contains the results. Did well in Midterm Did Poorly in Midterm Studying for Exam 80 20 Went Bar Hopping 30 70 If this sample is a good representation of the population, we can expect percent of those who did poorly on the midterm to have spent the weekend studying. 10 22.22 45 50

answer: 8

step-by-step explanation:

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
