Rain Fall (x) 13.1 11.4 16.0 15.1 21.4 12.9 9.6 18.2 18.6

Yield (y) 48.5 44.2 56.8 80.4 47.2 29.9 74.0 74.0 76.8

In an area of the Midwest, records were kept on the relationship between the rainfall (in inches) and the yield of wheat (bushels per acre). The data for a 9 year period is given in the table. The equation of the line of best fit for this data is y = 47.3 + 0.78x. How many bushels of wheat per acre can be predicted if it is expected that there will be 17 inches of rain?

Jaxson Sutton · Answer 1

Because rainfall is x, x = 17 so this question is now just a simple plug and chug

y = 47.3 + 0.78 (17) = 60.56

the answer is C
