Bruce just rode the Batmobile roller coaster. The ride climbed to its peak 757575 meters above the ground. Then, it dropped 95.395.395, point, 3 meters into an underground tunnel.
The following equation describes this situation.
\quad 75 +(-95.3) = -20.375+(−95.3)=−20.375, plus, left parenthesis, minus, 95, point, 3, right parenthesis, equals, minus, 20, point, 3
What does -20.3−20.3minus, 20, point, 3 tell us? please help now!

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
