Question

1 mark for review the bar graph summarizes the charge, in kilowatt - hours (kwh), a battery received each day for 15 days. bar graph with x - axis: charge (kwh) labeled 0, 8, 9, 11, 16, 23; y - axis: number of days labeled 0 to 7. bars: 0 kwh has height 6, 8 kwh has height 1, 9 kwh has height 2, 11 kwh has height 4, 16 kwh has height 1, 23 kwh has height 1 for how many of these 15 days did the battery receive a charge of 0 kwh? a 0 b 1 c 4 d 6

Explanation:

Step1: Analyze the bar graph

The bar graph has the x - axis representing the charge in kWh and the y - axis representing the number of days. We need to find the number of days when the charge is 0 kWh.

Step2: Find the bar for 0 kWh

Looking at the bar corresponding to 0 kWh on the x - axis, the height of the bar (which represents the number of days) is 6. So we check the options, and option D has the value 6.

Answer:

D. 6
