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?
The function is: y = 47.3 + 0.78 x, where x represents the rainfall ( in inches ). For x = 127: y = 47.3 + 0.78 * 17 y = 47.3 + 13.26 y = 60.56 Answer: There will be 60.56 bushels of wheat per acre.
