Answer: 41%
Step-by-step explanation:
15 girls prefer biology.
Find the boys who prefer biology;
There are 36 girls in total so;
= 100 - 36
= 64 boys interviewed
14 boys prefer Physics
= 64 - 14
= 50 boys prefer Biology and Chemistry
7 out of the 31 who prefer chemistry are girls so the boys who prefer chemistry are;
= 31 - 7
= 24 boys
Boys who prefer Biology;
= 50 - 24
= 26 boys
Total who prefer biology;
= 15 girls + 26 boys
= 41 students
Percentage = 41/100 = 41%

Answer:
1,if Noah is 15 his cousin is 8 or 96 months
2, and when Noah's cousin is 132 months or 11 years old Noah will be 18
3,n-[[7]12]=age of Noah's cousin
Step-by-step explanation:
1,15-7=8
1 part 2, 8*12=96
2,132/12=11
2 part 2,
11+7=18
3,n-[[7]12]=age of Noah's cousin
4,n+[7/12]
if n=18
18+[7/12]
or
18+0.5833=18.5833
