The center of measure calculated was the average or mean. To get the mean of a set of numbers, we have to add all the numbers given and then divide them by the numbers.

In this case, the mean of 3,7,11,11,16 will be:

= (3 + 7 + 11 + 11 + 16) / 5

= 48/5

= 9.6

The drama club is planning a field

Inessa [10]

Answer:

$\frac{2}{3}s+8=48$ .

Step-by-step explanation:

If we indicate the amount of students in the drama club as"s", we know that $\frac{2}{3}s$ is attending to the trip.
We also know that there are will be 8 teachers in the trip as well.
If the total amount of persons that will go on the trip reachs 48, which is the sum of 8 teachers and the $\frac{2}{3}s$ of the students: $\frac{2}{3}s+8=48$ .

Then, the equation that describes the situation is $\frac{2}{3}s+8=48$ . If we subtract 8 from both sides of the equation, and then we have $\frac{2}{3}s=40$ , which means that s=60.
