Answer:
- B. When the peak temperature is 40°C, 72 units of electricity are used on average.
Step-by-step explanation:
We see the relationship is closer to linear in the interval 30 to 40
<u>Approximate points:</u>
- (30, 34) and (34, 54)
<u>The slope of the line:</u>
- m = (54 - 34)/(34- 30) = 20/4 = 5
<u>The line is:</u>
- y - 34 = 5(x - 30)
- y = 5x - 116
<u>At x = 40, the value of y would be:</u>
- y = 5*40 - 116 = 84
The closet option is B
