Answer:
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).
Step-by-step explanation:
To find the interval, we can just make the conversion of the values from pounds to kilograms.
Each kilogram has 2.2 pounds. So, to realize the conversion from pounds to kilograms, we divide by 2.2.
Confidence interval: (102.3 pounds, 106.5 pounds).
102.3 pounds = 102.3/2.2 = 46.5 kilograms
106.5 pounds = 106.5/2.2 = 48.41 kilograms
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).

Answer:
f(x) = 9x - 1,200
Step-by-step explanation:
Let x represent the number of movie tickets sold.
9x will represent the profit made from selling movie tickets that day, since each ticket is 9 dollars.
To determine the profit, subtract 1,200 from 9x.
9x - 1,200 will represent the profit. Turn this into a function:
f(x) = 9x - 1,200 where x is the number of movie tickets sold and f(x) is the profit
