Tyson and his friends go ice skating. tyson must pay an initial fee of $18.30 plus $4.80 per hour. write an equation for the cost c tyson must pay after skating h hours. solve the equation to find the cost to go ice skating for four hours. write your answer as an ordered pair. a, c = 4.80h – 18.30 (4, 0.9) b. c = 4.80 + 18.30h (4, 78.00) c. c = 18.30 + 4.80h (4, 37.50) d. c = 18.30 + 4.80 + h (4, 27.10)

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
