Which equation can be used to find the answer? a state highway department plans to resurface 136 miles of highway during a six-month period. they have resurfaced 59 miles so far. how many more miles do they have left to resurface? a. m ÷ 2 = 59 m = 118 118 mi b. m + 59 = 136 m = 77 77 mi c. m – 59 = 136 m = 195 195 mi d. m ÷ 2 = 139 m = 278 278 mi

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
