Question

Find the weighted average of L=6 and M=14 , where L is weighted at 25% and M at 75%.(1 point) Responses 12 12 8 8 11 11 10

Answer 1

To calculate the weighted average of L and M, you can use the formula:

\[
\text{Weighted Average} = (L \times \text{weight of L}) + (M \times \text{weight of M})
\]

Given:
- \( L = 6 \) with a weight of \( 25\% \) or \( 0.25 \)
- \( M = 14 \) with a weight of \( 75\% \) or \( 0.75 \)

Now, plug the values into the formula:

\[
\text{Weighted Average} = (6 \times 0.25) + (14 \times 0.75)
\]

Calculating each term:

\[
6 \times 0.25 = 1.5
\]
\[
14 \times 0.75 = 10.5
\]

Now, add these results together:

\[
\text{Weighted Average} = 1.5 + 10.5 = 12
\]

Thus, the weighted average is **12**.
