Answer:
No, this prediction does not make any sense because rainfall can not be negative.
Step-by-step explanation:
The given quadratic regression equation that shows the rainfall (in centimeters) for a city in different months is
[tex]y=-0.77x^2+6.06x-5.9[/tex]
At x=10
[tex]y=-0.77(10)^2+6.06(10)-5.9=-22.3[/tex]
It means the rainfall for month 10 is about -22.3 centimeters. It is a negative value and we know that the rainfall can not be negative.
Therefore this prediction does not make any sense because rainfall can not be negative.
