Liam is comparing the costs of phone plans at two different companies to determine which plan to buy. company a charges $50 each month plus an additional $10 per gigabyte of data used. company b charges $60 each month plus an additional $8 per gigabyte of data used. the following equation represents the cost of the phone plans for the two companies when they are equal, where g represents the amount of gigabytes of data used.

complete each of the statements below with the correct answer choice.

the cost of the phone plans will be the same for company a and company b when gigabytes of data are used.

if company a changes the cost of data per gigabyte to , then the two phone plans will never have the same cost.

if company b's initial monthly cost and the cost of data per gigabyte , then the cost of the two phone plans will always be the same.

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb. the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
