Step-by-step explanation:
Write an equation:
Trash a way : $25 + 0.25x
Garbage No More : $45 per month
so to make them equal we need to have enough trash in Trash A Way that it equals $45
25 + 0.25x =45
0.25x = 20
x = 80
So, you need to have 80 pounds of trash to make them equal

Step-by-step explanation:
Answer: The point estimator of the mean percentage of reservations that are canceled on the day of the flight is 4.85% .
Step-by-step explanation:
Given : A 90% confidence interval for the mean percentage of airline reservations being canceled on the day of the flight is (3.6%,6.1%).
We know that the sample mean is the best estimate of the population mean.
The point estimator of mean is half of the sum of limits of the confidence interval.
The sum of the limits of the confidence interval = 3.6%+6.1% =9.7%
The , Point estimator of mean = (sum of the limits) ÷ 2
= (9.7%) ÷ 2 = 4.85%
Hence, the point estimator of the mean percentage of reservations that are canceled on the day of the flight is 4.85% .
