Math Problem Statement
The coordinate 8 has a weight of and the coordinate - 4 has a weight of . What is the weighted average?
A. 4
B. 4.4
C. 6.8
D. 44
Solution
To calculate the weighted average, we need to know both the coordinates and their corresponding weights. However, the problem is missing the weights for the coordinates and . If you provide these weights, we can proceed with the calculation.
The general formula for the weighted average of two coordinates and with weights and is:
