Plzz 100 points

study the graph about seismic waves. what does the graph show?
the s and p waves travel the same distance through earth's crust in the same amount of time.
the p wave travels through earth's crust more quickly than the s wave travels.
it takes the p wave 18 minutes to travel 6,000 km through earth's crust.
it takes the s wave 11 minutes to travel 8,000 km through earth's crust.

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?
