You espect wint the 40% of 60:
40% of 60=(40/100)*60=(40*60)/100=24
Answer: you expect win 24 times.
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
hope this helps
You need another equation, other wise x can be anything, and y can be infinitely different solutions.
