Pls ! a copy center offers its customers two different pricing plans for black and white photocopies of 8.5 in. by 11 in. pages. customers can either pay $0.08 per page or pay $7.50 for a discount card that lowers the cost to $0.05 per page. write and solve an equation to find the number of photocopies for which the cost of each plan is the same. 08c = .05c + 7.50; c = 250 .05c = .08c + 7.50; c = 22.5 .08c = .05c – 7.50; c = 250 7.50 = .08c + .05c; c = 58

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
