A particle moves along the curve LaTeX: y=\sqrt{1+x^3}y = 1 + x 3. As it reaches the point (2 , 3), the y-co-ordinate is increasing at a rate of 4 cm/s. How fast is the x-co-ordinate of the point changing at that instant? Round your answer to 2 decimal places.

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
