On a fishing trip, mark caught twenty - four fish. he caught some rock fish averaging 2.5 pounds and some blue fish averaging 8 pounds. the total weighted the fish was 137 pounds. how many of each fish did he catch?

Ineed if you could explain and give me the answer you! this needs done

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

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?
