Answer:
MAD = 2
Step-by-step explanation:
<u><em>First We'll find the mean of data</em></u>
Mean = 
Mean = 4
<u><em>Then, we'll find absolute deviation</em></u>
=> |4-3| = 1
=> |4-2| = 2
=> |4-1| = 3
=> |4-1| = 3
=> |4-3| = 1
<em><u>Now, taking the mean of these absolute deviations:</u></em>
MAD = 
MAD = 
MAD = 2
Pi, square root 72, and square root 2.
<u><em>Answer:</em></u>
a. The point (4,9) appears in both tables
<u><em>Explanation:</em></u>
<u>Note:</u> This question can be solved without the need of the tables
<u>A solution of a system of equations</u> is defined as a point (or set of points) that satisfy both equations
<u>This means that,</u> this point should belong to all the equations in the system
Now, a table is used to show a set of points that belong to a certain line
This means that, all vales in the table belong to the line they represent
<u>Since the point (4,9) appears in both tables</u>, therefore, it belongs to both lines and, therefore, is a solution to the system of equations consisting of these two lines
