Question

The bar graph shows the distribution of the number of walnuts per container for $20$ containers at a grocery store.

How many of these containers of walnuts contain exactly $78$ walnuts?

A.

$2$

B.

$7$

C.

$20$

D.

$78$

Accepted Answer

Choice B is correct. The height of each bar in the graph shown represents the number of containers that contain the number of walnuts specified at the bottom of the bar. The bar for 78 walnuts has a height of 7 . Therefore, 7 of these containers of walnuts contain exactly 78 walnuts. Choice A is incorrect. This is the number of containers that contain exactly 75 walnuts, not 78 walnuts. Choice C is incorrect. This is the total number of containers of walnuts represented in the bar graph, not the number that contain exactly 78 walnuts. Choice D is incorrect. This is the number of walnuts in a container that contains exactly 78 walnuts, not the number of containers that contain exactly 78 walnuts.
