(Hi! I figure out how to calculate the finance charge. If anyone could do a step by step that would be very helpful!!) Maya’s credit card has an APR of 11.84% and a billing cycle of 30 days. The table below shows her transactions with that credit card in the month of September.

(There is supposed to be a table here so I did the best I could to make it accurate to original. )

Date Amount($) Transaction
9/1 395.61 Beginning balance
9/8 24.13 Purchase
9/13 68.57 Payment
9/26 31.77 Purchase

Find Maya’s finance charge for September using the previous balance method, the adjusted balance method, and the daily balance method.

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.
