60 students study a language at a school.
1 answer:
- The number of girls is 24.
- The number of boys that study French is 24.
- The numbber of boys that study German is 12.
- The number of girls that study French is 16
- The number of girls that study German is 8.
<h3>How to fill the frequency tree?</h3>
The number of girls = total number of students - total number of boys
60 - 36 = 24
The number of boys that study French = 2/3 x 36 = 24
The numbber of boys that study German = 36 - 24 = 12
The number of girls that study French = 40 - 24 = 16
The number of girls that study German = 24 - 16 = 8
