Answer:

MAD = 2

Step-by-step explanation:

<u><em>First We'll find the mean of data</em></u>

Mean = \frac{20}{5}

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 = \frac{1+3+3+2+1}{5}

MAD = \frac{10}{5}

MAD = 2

Which system of inequalities is represented by the graph?
melisa1 [442]

Answer:

Option 3 is the correct answer.

Step-by-step explanation:

In this graph the red area is above the line y = -1 which represents y ≥ (-1)

Another graph is of a line y = mx + c which passes through (2, -1) and (0, 0)

where m = (y-y')/(x-x') = (1+0)/(0-2) = -1/2

and y intercept c = 0

Therefore line is y = -1/2x

and the blue area will be y ≤ -1/2x below the line.

Hence Option 3 is the answer.
