6. A ball is tossed in the air with an initial velocity of 19 ft/sec from a height of 3.5 feet. Which of the following equations represents the ball's height, h, in feet over time, t, in seconds? А) h = -19t2 + 3.5 B) h = -16t2 + 19t + 3.5

C) h= -4.9t2 + 190 + 3.5

D)h = -4.9t2 + 16t + 3.5

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
