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


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 \(8\) and \(-4\). If you provide these weights, we can proceed with the calculation.

The general formula for the weighted average of two coordinates \( x_1 \) and \( x_2 \) with weights \( w_1 \) and \( w_2 \) is:

\[
\text{Weighted Average} = \frac{x_1 \cdot w_1 + x_2 \cdot w_2}{w_1 + w_2}
\]

Please provide the missing weights so that I can help you further.
