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.
