The table contains the proof of the relationship between the slopes of two perpendicular lines. What is the reason for statement 2?
ОА Parallel line segments that meet a common perpendicular line are proportional in length.
OB. The lengths of vertical and horizontal sides in congruent triangles are in a common ratio.
OC Trigonometric identities determine the lengths of the legs in a right triangle.

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
