Gender Grade 9 Grade 10 Grade 11 Grade 12 Male 53 19 27 37 Female 31 42 50 61 What percentage of females are in grades 11 and 12? Round to the nearest percent. (1 point) Responses 27% 27% 35% 35% 60% 60% 67%
To calculate the percentage of females in grades 11 and 12, we can add the number of females in each grade:
Grade 11 and 12 females = 50 + 61 = 111
Now, we need to find the total population of females by adding up the number of females in each grade:
Total females = 31 + 42 + 50 + 61 = 184
To find the percentage, we divide the number of females in grades 11 and 12 by the total number of females, and then multiply by 100:
Percentage = (111/184) * 100 = 60.326 * 100 ≈ 60%
Therefore, the percentage of females in grades 11 and 12 is approximately 60%.
