Question

Can someone please help me with these couple questions I don’t really understand how to read this graph

1. How many hours does the heater run on Tuesday?

2. Which object runs 11 hours on Saturday?

3. Which object has the biggest difference between weekdays and weekends?

4. If this graft is for winter electricity usage, how do you think it would be different for summer?

Answer 1

1. 7.5 hours

2. TV

3. Computer

4. All electronic usage except for the heater would decrease because summer is usually when people go outside and don't really stay indoors. While in winter, most people stay inside their houses.
