Answer 2

Question:

38 boys and 22 girls visit a zoo 33 of these children have a voucher twice as many boys as girls do not have a voucher answer in a frequency tree(Answer in a frequency tree)

Given:

• Number of boys: 38

• Number of girls: 22

• Number of Children have a voucher: 33

• Twice as many boys as girls do not have a voucher

Solution:

Finding:

Total Number of Students:

• Sum of boys + girls : 38 + 22 = 60

Number of Children who don't have a voucher:

• Total Number of Children - Number of Children who have a voucher : 60 - 33 = 27

We Know That,

Twice as many boys as girls do not have a voucher

• Let 2x be number of boys who don't have a voucher

Now,

Both Gírls and Bóys without voucher: x + 2x = 27

$3x = 27 \\ \\ x = \frac{27}{3} \\ \\ x = 9$

We get,

Gírls who don't have a voucher: x = 9

Bóys who don't have a voucher: 2x = 2(9) = 18

For frequency tree:

• Total students: 60
• Bóys: 38
• Bóys who don't have a voucher: 18
• Bóys who have a voucher: 20
• Gírls: 22
• Gírls who don't have a voucher: 9
• Gírls who have a voucher: 13

Hope it helps ya!!
