The image shown has two triangles sharing a vertex: There are two triangles labeled UVW and WXZ with a common vertex W. In triangle UVW, angle VUW is labeled as y, and angle WVU is labeled as 50 degrees. In triangle WXZ, angle WXZ is labeled as 50 degrees. What is the measure of ∠WZX, and why?

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
