Question

The coordinate 3 has a weight of 2, and the coordinate 8 has a weight of 3.

Answer 1

The weighted average of coordinate 3 which  has a weight of 2, and the coordinate

8 which has a weight of 3 is 6.

We have been given the coordinates with their specific weights. Thus we will find the weighted average.

Weighted average is a calculation that takes into account the varying degrees of importance of the numbers in a data set. The formula to find the weighted average is given by

                               W = Σwixi/Σwi     (1)

Where,   xi = are the variable

                wi = are specific weights for the variable

First we will find ,    Σwixi = w1x1 + w2x2

    Here w1 = 3   ,          x1 = 2

              w2 = 8,            x2 = 3

Putting these values we get,

                     Σwixi = 3*2 + 8*3

                               = 6 + 24

                               = 30

Also, Σwi = w1 + w2

                = 2 + 3

                = 5

Putting the required values in equation (1) we get,

W = 30/5

W = 6

Thus, the weighted average is 6
