The weighted average of the coordinates is of 5.

What is the weighted mean?

The weighted mean is given by the sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights.

This data-set is composed by:

  • Element 3 with a weight of 2.
  • Element 7 with a weight of 2.

Hence the weighted average is:

M = (3 x 2 + 7 x 2)/(2 + 2) = 20/4 = 5.

The weighted average of the coordinates is of 5.
