If f(–2) = 0, what are all the factors of the function f(x)=x^3 -2x^2-68x-120 use the remainder theorem. a) (x + 2)(x + 60) b) (x – 2)(x – 60) c) (x – 10)(x + 2)(x + 6) d) (x + 10)(x – 2)(x – 6)

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
