△abc has interior angles with measures x°, 90°, and 70°, and △def has interior angles with measures y°, 70°, and 20°. using the given information, which statement is true? a. the two triangles are not similar because x≠y . b. the triangles are similar because they each have an interior angle with a measure 70°. c. the two triangles are not similar because the interior angles are congruent but the side lengths are different. d. the two triangles are similar because y=90 .

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
