Sagot :

Using the weighted mean, the coordinates of P when point c has a weight of 3, and point E has a weight of 5 is of P = -1.77.

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.

For this problem, the points and weights are given as follows:

  • D = 2 has a weight of 3.
  • B = -6 has a weight of 9.
  • A = -9 has a weight of 2.
  • C = -1 has a weight of 3.
  • E = 6 has a weight of 5.

Hence the weighted mean is given as follows:

P = (2 x 3 - 6 x 9 - 9 x 2 -1 x 3 + 6 x 5)/(3 + 9 + 2 + 3 + 5) = -1.77.
