As per linear equation, Donald can go with the given gallons of gas is 276 miles.
The total cost of the gas used is $28.98.
"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. When this equation is graphed, it always results in a straight line."
Given, Donald's car gets about 30 miles per gallon.
Donald drive on 9.2 gallons of gas.
Therefore, total distance that Donald can go with the given gas is
= mileage of the car × total amount of gas
= 30 × 9.2 miles
= 276 miles
Again, cost of gas per gallon is $3.15.
The total cost
= total gallons of gas used × cost of gas per gallon
= $(9.2 × 3.15)
= $28.98

No, any one of the 10 mayflies in the group live for 1 full day.
The mean absolute deviation (MAD) is a measure of variability that indicates the average distance between observations and their mean.
The life spans of 10 adult mayflies have a mean of 4 hours and a MAD of 2 hours.
Fill in the table below with possible values for the life spans. You can use the same values more than once.
Mean = 4 hours.
Mean absolute deviation = 2 hours.
Assume that the life spans of each fish is 4 hours;
Then mean = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4/10
= 40/10
= 4 hours.
No fish can live for a full day.
Hence, No, any one of the 10 mayflies in the group live for 1 full day.

Step-by-step answer:
Assuming MAD stands for mean absolute deviation (2 hours), then the total absolute deviation from the mean (4 hours) is 10*2=20 hours.
If one of the flies live for 1 full day, the absolute deviation is 24-4=20 hours. This automatically requires the other flies live exactly 4 hours to have the MAD equal to 20 hours.
However, the above arrangement does not give a mean of 4 hours, but a mean of (24+9*4)/10=6 hours. This means that it is not possible to have a fly living for a full day.
