Question

You want to collect data on how many teachers have children. You decide to ask 5 random teachers from each grade level in Glades Middle school, for a total of 15 teachers. 9 of them have children. If there are 58 teachers at Glades Middle, how many teachers can you expect to have children?

Answer 1

Answeer:

34 teachers

Step-by-step explanation:

If for a total of 15 teachers. 9 of them have children, we can express this as;

15 teachers = 9 children .... 1

To calculate the number of teachers we are expected to have children for 58 teachers, we can express this as;

58 teachers = x ....2

Divide both expressions

15/58 = 9/x

Cross multiply

15x = 9 * 58

15x = 522

x = 522/15

x = 34.8

Hence 34 teachers is expected to hae children
