Q
J played four games. Her modal score was 76 and her mean score was 75.
Her range of scores were 10.
What were her scores for the four games?
A
Multiply the mean by the number of games > 75 (4) = 300.
76+76=152
300-152= 148.
Set up two equations to find which numbers add up to make 148
X+Y=148
X-Y=10
2X = 158. X = 79.
To find the range minus 10 from 79 = 69.
Four numbers: 69, 76, 76, 79.
