The residual is 0.75
Step-by-step explanation:
Recall that the residual is the VERTICAL distance between the y-value of the data point and the y-value of the predicted line. This distance can be calculated using the absolute value of the difference between these y-values.
Therefore, in our case the residual is: |32 - 32.75| = |-0.75| = 0.75
Answer:
7
Step-by-step explanation:
So the log thingy is loga(b) = c
