liam and tehya are trying to determine whether δabc and δefd can be proven congruent through rigid motions.

liam says that δabc ≅ δefd because δabc can be reflected over the y-axis to create δefd.

tehya says that δabc ≅ δefd because δabc can be rotated 90° clockwise about the origin to create δefd.

who is correct?

liam only
tehya only
both liam and tehya
neither liam nor tehya

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
