To find the weighted average, you can use the formula:
\[ \text{Weighted Average} = (L \times w_L) + (M \times w_M) \]
where:
- \( L = 6 \) with a weight \( w_L = 0.25 \) (25%)
- \( M = 14 \) with a weight \( w_M = 0.75 \) (75%)
Now substitute the values into the formula:
\[ \text{Weighted Average} = (6 \times 0.25) + (14 \times 0.75) \] \[ = 1.5 + 10.5 \] \[ = 12 \]
Therefore, the weighted average of L and M is 12.
