Ronin and Tom spend a certain amount of money from their money box each month to buy plants. The table shows the relationship between the amount of money (y) remaining in Ronin's money box and the number of months (x): Number of Months
(x)

Amount Remaining (dollars)
(y)

The equation shows the relationship between the amount of money, y, remaining in Tom's money box and the number of months, x:

Function 2:
y = −4x + 70

Which statement explains which function shows a greater rate of change?
Function 2 shows a greater rate of change, because Tom spends $70 each month and Ronin spends $9 each month.
Function 2 shows a greater rate of change, because Tom spends $66 each month and Ronin spends $9 each month.
Function 2 shows a greater rate of change, because Tom spends $4 each month and Ronin spends $3 each month.
Function 1 shows a greater rate of change, because Ronin spends $3 each month and Tom spends –$4 each month.

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.
