The population in a certain town is increasing linearly each year. The population at time t=4 is 1580 and at time t=7 is 2000, where t is the number of years after 1990. If P(t) is the population at time t, which of these equations correctly represents this situation?
Select the correct answer below:

P(t)=155t+915

P(t)=150t+950

P(t)=155t+960

P(t)=140t+1010

P(t)=150t+980

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.
