Which linear equations have one solution? Check all that apply. 5x – 1 = 3(x + 11) 4(x – 2) + 4x = 8(x – 9) 4(x – 6) + 4 = 2(x – 3) 2(x – 4) = 5(x – 3) + 3 2(x – 1) + 3x = 5(x – 2) + 3

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
