Answer 1

Answer:

30%

Step-by-step explanation:

Age             No. of volunteers

10-14                     3

15-19                     2

20-24                   7  

25-29                   8    

30-34                   5    

35-39                   5  

Total no. of volunteers = 3+2+7+8+5+5 =30

Now we are supposed to find What percent of the volunteers was at least 15 years old but no more than 24 years old

15-19                     2

20-24                   7  

So, total no. of volunteers was at least 15 years old but no more than 24 years old = 7+2=9

So, percentage of volunteers was at least 15 years old but no more than 24 years old:

= $\frac{9}{30} \times 100$

= $30\%$

Hence 30 % of volunteers was t least 15 years old but no more than 24 years old.
