18 Heather and Adam both solve the same problem 2(3r-6) = 10r - 10.
Which one of them is correct?
Adam
2(3r-6) = 10r - 10
6r - 12 = 10r - 10
-12 = 4r - 10
-2 = 4r
1
r=-
2
Heather
2(3r -6 ) = 10r β 10
6r - 6 = 10r - 10
-6 = 4r -10
4 = 4r
r = 1

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 aΓ’β Β΅ect the mean and standard deviation of the wait time until success?
