In an area of the midwest, records were kept on the relationship between...
47.3 + .78(17)
= 47.3 + 13.26
Given: Data is in terms of rainfall (in inches) and Yield of wheat (bushels
Equation of Best fit line for 9 year of data is Y = 47.3 + 0.78X
To find: Bushels of wheat per acre when 17 inches of rain expected.
Given problem is of Regression analysis as we are given with best fit line.
From the Equation of Best fir line we can conclude that it is equation of line Y on X because when put value of X we get value of Y.
From Given Data, let say X be Rainfall length and Y be Yield of wheat.
So, to find the Bushels of wheat (yield) when 17 inches of rainfall is expected.
we put value X = 17 in given equation.
⇒ Y = 47.3 + 0.78 × ( 17 )
⇒ Y = 47.3 + 13.26
⇒ Y = 60.56
Therefore, 60.56 bushels of wheat per acre can be predicted if 17 inches of rain is expected.
y = 47.3 + 0.78x. for x=17
put 17 in function

4) 16 birdhose
he akes 2 birdhouse in 30 minute
so 4 in 1 hr(60 min)
16 in 4 hr
the answer is 14ft
