Mary wants to determine the average height of the plants in her plant collection. She measures them and finds their heights are 8 inches, 7.5 inches, 11 inches, 6.5 inches, and 14 inches. What is the average height of her plants?
The average is all the numbers added up divided by the amount of plants measured. This would be 7.5 + 11 + 6.5 + 14 + 8 all divided by 5. This average is 47/5 which is 9.4 inches.
