Question

alexander has a part - time job at an ice skating rink selling hot cocoa. he decided to plot the number of hot cocoas he sold relative to the day’s high temperature and then draw the line of best fit. calculate the residual for the data point that corresponds to 109 hot cocoas sold and a high temperature of 3°f.

Explanation:

Step1: Recall residual formula

Residual = Observed value - Predicted value

Step2: Identify given values

Observed value = 109, Predicted value (from line at $x=3$) = 108

Step3: Calculate residual

$\text{Residual} = 109 - 108$
