The ages, in years, of children on the swim team are 10, 11, 12, 12, 11, and 13. what is the mean age of a child on the swim team?

11.5

Step-by-step explanation:

To find the mean first add all the numbers then divide by the amount of numbers you added.

10 + 11 + 12 + 12 + 11 + 13 = 69

69/6 = 11.5

Step-by-step explanation:

By definition the Mean is the average of a set of numbers.

In this case, we know that the ages in years of children on the swim team are  the following:

10, 11, 12, 12, 11, and 13

Then, to calculate themean age of a child on the swim team, we need to add up all the numbers and divide this by the total number of values in the set.

You can observe that there are six values. Then, the mean age of a child on the swim team is:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
