Answer 1

ANSWER

The number of children between the ages of 9 and 15 who visited the park is

`20`


Step-by-step explanation


The number of children between the ages of 9 and 15 who visited the park are those within the age group 9 to 12 and 12 to 15.


We can from the graph that, the height of the bar that corresponds to the age group 9 to 12


`= 14`
and the height of the bar that corresponds to the age group 12 to 15


`= 6`


The sum of the two frequencies


`= 14 + 6 = 20`
