Low-fuel landing 25% instrument failure 15% bad weather 5% failed landing gear 15% engine failure 20% autopilot failure 15% normal conditions 5% at a flight-training academy, each pilot is given an emergency condition in a simulator during testing (the probabilities are shown in the table). in the current class, 25 trainees failed the test and 115 passed. how many trainees were tested in the most common scenario? 25 35 15 10 © 2015 edmentum. all rights reserved.

The weight v of an object on venus varies directly with its weight e on earth. a person weighing 120 lb on earth would weigh 106 lb on venus. how much would a person weighing 150 lb on earth weigh on venus?

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?
