At a university, 1200 students are enrolled in engineering. There are twice as many in electrical engineering as in mechanical engineering, and three times as many in
chemical engineering as there are in mechanical engineering.
19. Which system of equations represents the number of students in each program?
Fc+ m + e = 1200, 2m= e, 3m=c Hc+m+e= 1200, 3m= e, 2m=c
Gc+ m +e= 1200, 2e = m, 3c= m
J c+m+e= 1200, 2m= e, 3m=2e

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
