a.
To find: Organize the gas mileages in matrix.
a.

Answer to Problem 1CYU
Explanation of Solution
Given equation:
Table that shows the city and highway gas mileage of different types of vehicles.
From the given table
We can write a matrix of gas mileages of five different types of vehicles,
First rows represent the City and Second row represents the Highway.
Columns represents the five different vehicles.
Therefore,
Requires matrix is
b.
To find: Add the elements of each row and interpret the results.
b.

Answer to Problem 1CYU
Sum of elements of First row = 168
Sum of elements of second row = 200
Explanation of Solution
Given equation:
Table that shows the city and highway gas mileage of different types of vehicles.
Requires matrix is
Sum of elements of First row =
Sum of elements of First row it represents for row City.
Sum of elements of Second row =
Sum of elements of Second row it represents for row Highway.
c.
To find: Add the elements of each row and interpret the results.
c.

Answer to Problem 1CYU
Sum of elements of First column = 48
Sum of elements of second column = 45
Sum of elements of third column = 53
Sum of elements of fourth column = 91
Sum of elements of fifth column = 131
Explanation of Solution
Given equation:
Table that shows the city and highway gas mileage of different types of vehicles.
Requires matrix is
Sum of elements of First column =
Sum of elements of Second column =
Sum of elements of third column =
Sum of elements of fourth column =
Sum of elements of fifth column =
Sum of each column represents for each vehicle of five different types.
