Chose all of the equations that have infinitely many solutions. please hurry A. 3(x + 4) = 2x - 7
B. 3x + 8 - x = 3 + 5 + 2x
C. 1/2 (4x - 8 ) = 2x - 4 + 12
D. 5-4x + 7 = -2( 2x - 6 )
E. 4-3x - 8 = 2x + 7-5x

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?
