Question

question 2 of 10
this table shows the rainfall (in centimeters) for a city in different months. the quadratic regression equation that models these data is y = - 0.77x^2+6.06x - 5.9.

x (month)	y (rainfall (cm))
2	2
3	5
4	8
5	4
6	3

using this model, the predicted rainfall for month 11 is about - 32.4 centimeters. does this prediction make sense? why or why not?

a. no, because you cant measure rainfall in centimeters.
b. yes, because it is the result of substituting x = 11.
c. no, because you cant have a negative amount of rainfall.
d. yes, because the rainfall is declining.

Explanation:

Rainfall is a physical quantity representing the amount of water falling as rain. It cannot be negative in the real - world context. A negative value for rainfall does not make sense.

Answer:

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