Quizplus · Accepted Answer

To find the number of people who are 10 years of age or older but less than 40 years of age, we need to add up the frequencies for the age groups 10-19 and 20-29. 
10-19: 25 people
20-29: 26 people
25 + 26 = 51 people. Therefore, the answer is C. The frequency table shows that there are 39 people who are 10 years of age or younger, and 10 people who are 40 years of age or older. Therefore, the number of people who are 10 years of age or older but less than 40 years of age is 100 - 39 - 10 = 51.
