Question: (Graph attached below)

Answer 1

The histogram shows the heights in meters of trees in a certain section of a park.  

How many trees are less than 20 meters tall?

Answer: From the given histogram, we clearly see:

There is 1 tree with height less than 8 meters

There are 1 + 2 = 3 trees with height less than 12 meters

There are 3 + 2 = 5 trees with height less than 16 meters

There are 5 + 4 =9 trees with height less than 20 meters.

Therefore, the correct option is B. 9
