Enter your answer, as a decimal, in the box

Answer 1

To find Alisha's final score, we need to calculate the weighted average of her scores in each category, using the given weights.

First, let's calculate the average score for each category:

Average creativity score = (18 + 16 + 15 + 16)/4 = 16.25
Average execution score = (20 + 19 + 20 + 18)/4 = 19.25
Average style score = (12 + 15 + 14 + 13)/4 = 13.5

Next, we can calculate the weighted average of her scores using the given weights:

Weighted average = (0.5 * average creativity score) + (0.3 * average execution score) + (0.2 * average style score)
= (0.5 * 16.25) + (0.3 * 19.25) + (0.2 * 13.5)
= 8.125 + 5.775 + 2.7
= 16.6

Therefore, Alisha's final score is 16.6.
