I need a point to this question in order to answer it
Answer:
Coordinate D. Because D lies on the 2nd quadrant, meaning that x has a negative value whereas y is positive.
X f πxf
-1 2 -2
3 1 3
-1 -2 2
0 -3 0
total =3
mean (π)=πxf ÷n
= 3÷4
= 0.75 these is not answer I thank so
The answer is 5 x -3 + 4 x 2 / 2 = -15 + 8 / 2 = -11
