A tee box is 128 feet above its fairway. When a golf ball is hit from the tee box with an initial vertical
velocity of 32 ft/s, the quadratic equation 0 = -16t2 + 32 + 128 gives the time t in seconds when a golf
ball is at height o feet on the fairway.
Part 1
Solve the quadratic equation by factoring to see how long the ball is in the air.
The ball is in the air a total of 4
seconds.
Part 2 out of 3
What is the height of the ball at 1 second?
One second after being hit from the tee, the ball is
feet above the fairway.

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
