Question

if 200 people are surveyed, what percentage of the people surveyed had hazel eyes?
eye color | no. of people
hazel |
black | 12
blue | 58
brown | 92

Explanation:

Step1: Find the number of people with hazel eyes

First, we know the total number of people surveyed is 200. The number of people with black, blue, and brown eyes are 12, 58, and 92 respectively. So we calculate the number of people with hazel eyes by subtracting the sum of the other groups from the total.
Sum of people with black, blue, and brown eyes: $12 + 58 + 92 = 162$
Number of people with hazel eyes: $200 - 162 = 38$

Step2: Calculate the percentage of people with hazel eyes

The formula for percentage is $\frac{\text{Number of people with hazel eyes}}{\text{Total number of people surveyed}} \times 100\%$
Substitute the values: $\frac{38}{200} \times 100\% = 0.19 \times 100\% = 19\%$

Answer:

19%
