Values of x and y will be 12 and 5 respectively.
It's given in the question,
- Three points Q, R and S are collinear.
- Coordinates of Q → (2, 0)
- Coordinates of R → (8, 3)
- Coordinates of S → (x, y)
- QR : RS = 3 : 2
Since, expression for the coordinates of a point (h, k) which divides the segment joining points and
in the ratio of m : n is given by,
h =
k =
Since, R is a point on segment QS dividing in the ratio of 3 : 2, coordinates of R will be,
Similarly,
Therefore, values of x and y will be 12 and 5 respectively.

Answer:
2.4
Step-by-step explanation:
We have to find the mean first
Now we have to find deviations.
Note that the deviations are calculated by subtracting the mean from the value. The distance is always positive so the deviations will be positive
Value Deviation
2 2-4.5 = |-2.5| = 2.5
4 4-4.5 = |-0.5| = 0.5
7 7-4.5 = 2.5
2 2-4.5 = |-2.5| = 2.5
3 3-4.5 = |-1.5| = 1.5
7 7-4.5 = 2.5
9 9-4.5 = 4.5
3 3-4.5 = |-1.5| = 1.5
1 1-4.5 = |-3.5| = 3.5
7 7-4.5 = 2.5
The last step is to find the mean of deviations.
The mean absolute deviation of given data set is 2.4 ..
