The time it takes for the music player to fall from the bridge to the bottom of the ravine can be modeled by the following equation: where t is the amount of time since the construction worker dropped his music player.

Will the safety balloon release in time?
First, how long will it take for the music player to fall to the bottom of the ravine? Solve the equation and find the values of t. (2 points: 1 point for each value)

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?
