find the weighted average of the weighted points on the number line. a number line with four weighted points plotted. the point at negative 4 has weight three, the point at negative 2 has weight three, the point at one has weight one, and the point at five as weight three.

Respuesta :

The weighted average of the weighted points on the number line is -0.2.

A weighted average refers to the average of a data set that considers certain numbers as more important. Weighted averages are commonly used in statistical analysis, stock portfolios and teacher grading averages. In order to determine the weighted average of the weight points on the number line:

  1. Determine the sum of weight value of each number. Weight value sum = (-4*3) + (-2*3) + (1*1) + (5*3) = -12 – 6 + 1 + 15 = -2
  2. Determine the sum of weight points. Sum of weights = 3 + 3 + 1 + 3 = 10.
  3. Divide the sum of weight value by weight value sum. Weighted average = -2/10 = -0.2

Hence, the average weight is -0.2.
