A segmented bar chart was created showing the lunch preference by grade. What percent would the bar for 12th graders show for preferring chicken wings?
54%
30%
27%
10.8%

Answer 1

10.8%

Explanation:

I took the STAT test

Answer 2

To find the percent of 12th graders who preferred chicken wings, we need to find the proportion of 12th graders who chose chicken wings and then express that as a percentage.

First, let's find the total number of 12th graders:

12th graders = 24 + 27 + 39 = 90

Next, let's find the proportion of 12th graders who chose chicken wings:

proportion = number of 12th graders who chose chicken wings / total number of 12th graders = 24 / 90 = 0.2667

Finally, let's express this proportion as a percentage:

percentage = proportion * 100 = 0.2667 * 100 = 26.67%

So, the bar for 12th graders in the segmented bar chart would show 26.67% for preferring chicken wings.

Therefore, the correct answer is 27%.
