Question

using this model, the predicted rainfall for month 11 is about -32.4 centimeters. does this prediction make sense? why or why not?
a. yes, because it is the result of substituting x = 11.
b. yes, because the rainfall is declining.
c. no, because you cant have a negative amount of rainfall.
d. no, because you cant measure rainfall in centimeters.

Explanation:

Rainfall is a physical quantity representing the amount of water from precipitation. A negative value for rainfall does not make sense in the real - world context as you cannot have a negative amount of water falling as rain. Option A only focuses on the mathematical substitution but ignores the physical meaning. Option B is incorrect as the decline does not justify a negative value. Option D is wrong because rainfall can be measured in centimeters.

Answer:

C. No, because you can't have a negative amount of rainfall.
