Question

Which expression represents the average of three test scores? O X+y+Z O 3(x+y+z) o **** X+y+Z 3 om ΧΟΣ 3

Answer 1

We need to find the expression that represents the average of three test scores

At first : the average = the sum of the data over the number of the data

We have 3 test scores : x , y and z

The sum of the scores = x + y + z

The number of the scores = 3

so, the average will be :

$\frac{x+y+z}{3}$

So, the answer is : ( x + y+ z )/3
