Georgia is 4 feet 2 inches tall. There are 12 inches in a foot.

Use the conversion 1 inch = 2.5cm to convert her height into metres.

12(4)= 48

Add on the inches = 50

50 (2) = 100 50(0.5) = 25

125cm- to convert into m divide by 100 = 1.25

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?

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.
