Question

The bar graph summarizes the charge, in kilowatt-hours $(kWh)$ , a battery received each day for $15$ days.

For how many of these $15$ days did the battery receive a charge of $0 kWh$ ?

A.

$0$

B.

$1$

C.

$4$

D.

$6$

Accepted Answer

Choice D is correct. It's given that the bar graph summarizes the charge, in kilowatt-hours kWh , a battery received each day for 15 days. The height of each bar in the bar graph shown represents the number of days the battery received the charge, in kWh , specified at the bottom of the bar. The bar for a charge of 0 kWh reaches a height of 6 . Therefore, the battery received a charge of 0 kWh for 6 of these days. Choice A is incorrect. This is the charge, in kWh , that the battery received, not the number of days the battery received this charge. Choice B is incorrect. This is the number of days the battery received a charge of either 8 , 16 , or 23 kWh . Choice C is incorrect. This is the number of days the battery received a charge of 11 kWh .
