Answer 1

Hi Sam are you on stretch your thinking

Answer 2

to find the mean you add all the numbers then divide the sum by how many numbers there are :

1)Ford School

21+19+20=60

there are 3 numbers in the equation so you divide 60 by 3 :

60÷3=20

the mean for Ford School is 20

2)Carter School

41+36+37=114

there are 3 numbers in the equation so you divide 114 by 3 :

114÷3=38

the mean for Carter School is 38
