Answer:
mean = 2
MAD = 3/4
Step-by-step explanation:
1, 3, 2, 2, 1, 3, 3, 1
To find the mean, add up all the numbers and then divide by the number of terms
(1+ 3+ 2+ 2+ 1+ 3+ 3+ 1)/8 = 16/8 = 2
To find the mean absolute deviation
subtract the mean and the number and then take the absolute value, add them together and then divide by the number of terms
|(1-2)| +|(3-2)| +| 2-2| +|2-2|+|1-2| +|3-2|+|3-2| +|1-2|

I am not sure if you need to simplify more.
Answer:
The augmented matrix is of two equations, and two variables.
Step-by-step explanation:
This is an augmented matrix, which means the constant terms are on the last column.
The matrix can be written as
X1 + kX2 = 3
-5X1 + 6X2 = 1
The constants are 3, 1, and all the coefficients of the variables, X1 and X2.
X1 and X2 can take any values.
k is constant, just like 1, -5, and 6.
Though, it is not specified, the consistency or inconsistency of the equation depends on the value k takes.
