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

Answer 1

To find the weighted average of L and M with their respective weights, you can use the formula:

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

Where:

• \( L = 6 \)
• \( M = 14 \)
• Weight of \( L = 0.25 \) (25%)
• Weight of \( M = 0.75 \) (75%)

Now, substituting the values:

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

Calculating each term:

1. \( 6 \times 0.25 = 1.5 \)
2. \( 14 \times 0.75 = 10.5 \)

Now, add them together:

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

Thus, the weighted average is 12.
