Sasha wants to buy some dresses over the Internet. Each dress costs $7.15 and has a shipping cost of $9.95 per order. If Sasha wants to spend no more than $60 for her dresses, which inequality shows the maximum number of dresses, p, that she can buy? 9.95 − 7.15p ≤ 60, so p ≤ 4
9.95p + 7.15p ≤ 60, so p ≤ 5
9.95p − 7.15p ≤ 60, so p ≤ 6
9.95 + 7.15p ≤ 60, so p ≤ 7

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
