Without doing any calculations, determine the missing number that will make the value of Expression B half the value of Expression A. A (8 + 54 + 91) × 12 B (8 + 54 + 91) × Enter your answer in the box.

41/2 - 1 1/3 what is the answer as a fraction?

If f(x)= sqrt4x+9+2, which inequality can be used to find the domain of f(x)?

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?
