散点图・拟合模型与残差挑战
During an experiment, the temperature, in degrees Celsius (ºC), of a mixture was recorded to the nearest integer at certain times. The scatterplot shows the recorded temperature y , in ºC, of the mixture x hours after the start of the experiment.
What was the average rate of change of the recorded temperature of the mixture over time, in ºC per hour, from x = 1 to x = 3?
