Hi there,
There are 16 members in a math club such as 2 girls and 14 boys in a math club.
The ratio would be:
1:7
Divide both terms by 2.
2 ÷ 2 = 1
14 ÷ 2 = 7
Therefore:
2 : 14 = 1 : 7
Answer:
The median is 19.45
Step-by-step explanation:
Organize the numbers from least to greatest
16.3, 17.8, 17.8, 18.0, 18.7, 19.3, 19.6, 20.1, 20.5, 21.9, 25.2, 25.4
Find the middle of the set of numbers
19.3 and 19.6
Add 9.3 and 19.6
19.3 + 19.6=
38.9
Divide by 2
38.9/2
Which is 19.45
Hope this helps
