Question

In Bonita Springs, in a private school, there are seven three year old kids, six four year old kids, and Fifteen five year old kids. Find the mean age. Round the mean age to the nearest hundredth.

Answer 1

To find the mean age of the students, calculate the sum of the ages and then divide it by the total number of students. The mean age is approximately 4.29 years.

Step-by-step explanation:

To find the mean age of the students, we need to calculate the sum of the ages and then divide it by the total number of students. Let's calculate:

• Number of three-year-old kids = 7
• Number of four-year-old kids = 6
• Number of five-year-old kids = 15

Now, let's calculate the sum of ages:

• Sum of ages for three-year-old kids: 7 * 3 = 21 years
• Sum of ages for four-year-old kids: 6 * 4 = 24 years
• Sum of ages for five-year-old kids: 15 * 5 = 75 years

Total sum of ages: 21 + 24 + 75 = 120 years

Now, let's calculate the mean age:

Mean age = Total sum of ages / Total number of students

Mean age = 120 / (7 + 6 + 15) = 120 / 28 = 4.29 years

Rounded to the nearest hundredth, the mean age is approximately 4.29 years.
