Question

a frisbee - golf club recorded the ages of its members and used the results to construct the histogram shown above. find the total number of members in the club. members find the number of members 25 years of age or younger. members find the percent of total members that are 25 years of age or younger. round the percent to two decimal places as needed. percent

Explanation:

Step1: Find total members

Sum the number of members in each age - group. The number of members in the age - groups 16 - 20, 21 - 25, 26 - 30, and 31 - 35 are 7, 3, 1, and 10 respectively. So the total number of members is \(7 + 3+1 + 10=21\).

Step2: Find members 25 or younger

Sum the number of members in the age - groups 16 - 20 and 21 - 25. That is \(7 + 3=10\).

Step3: Find percentage of members 25 or younger

Use the formula \(\text{Percentage}=\frac{\text{Number of members 25 or younger}}{\text{Total number of members}}\times100\). Substitute the values: \(\frac{10}{21}\times100\approx47.62\).

Answer:

Total number of members: 21
Number of members 25 years of age or younger: 10
Percent of total members that are 25 years of age or younger: 47.62
