A bakery sold 208 chocolate cupcakes in a day, which was 52% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?

Solve the system of equations y= 3/2 - 1, -x+ y =-3

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

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?
