Graph :
159 - 138 = 21
159 - 175 = 16
185 - 175 = 10
No, the system is inconsistent.
Step-by-step explanation:
If the last column is a pivot column, then that row gives an equation that looks something like 0x+0y+0z=1 , meaning , 0=1. Clearly, this is false.
So, the system of linear equations is inconsistent.
Here is what I got for the first one. MAD=
1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)
=1/5(|85-83|+|83-83|+|87-83|+|90-83|+|70-83|)
=1/5(2+0+4+7+13))
=5.2
And for the second one I got, MAD=
1/(N)*(|x1-xm|+|x2-xm|+..+|xN-xm|)
=1/5(|75-76|+|74-76|+|68-76|+|83-76|+|80-76|)
=1/5(1+2+8+7+4))
=4.4
The difference means subtract
89.4 - 13.621 = 75.779
