Joe is standing at a Point P of a parking lot that is in the shape of a right triangle as shown in the diagram. There is a fence along the longest side of the lot. Joe's distance to the fence is 15 meters. There is a sign on the fence at Point C. The distance from A to C is 8 meters. If the width of the lot, segment a, p, is 17 meters, then how long is the fence, segment a, b?'

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb.the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
