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?

Answers

Answer:

Step-by-step explanation:

Given: Data is in terms of rainfall (in inches) and Yield of wheat (bushels

           per acre)

           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.
Assuming x is the rainfall, you simply plug in 17 for x and solve for y.  

47.3 + .78(17)
= 47.3 + 13.26
= 60.56

What is the fraction ten twelves in its simplest form

Answers

You just divide each by one of there common factors (except from 1 and 0)

Eg.10÷2=5

     12÷2=6
This would look like:

10/12

Next look for a common divisor that works for both the top (numerator) and bottom (denominator) numbers. Incidentally, think 'Notre Dame' or ND if you cannot remember which is which.

Dividing by 2 works for both numbers, so dividing the '10' and the '12' by 2 gives you a simplified form of 5/6.

And voila! That's your answer!

A customer buys $17.01 of gas and request one $5 lottery ticket, two $1 lottery ticket and one $3 lottery tickets he gives you two winning tickets to redeem one for $5 and the other for $2. How much change what you receive from $100 bill.

Answers

So first add $5 and $2 to $100 so you have 107 dollars.

Then add 17.01 + 5 + 1 + 1 + 3 = 28.01. so then do 107 - 28.01 = $78.99

What is 8172 divided by 9?

Answers

First we can solve 8100 by 9. Since we know 81/9=9, then 8100/9=900.
72/9=8

Now we can add them together 900+8=908.

The answer is 908.
8172/9=908 the answer is 908

What is the slope of the line that contains the points (-1,2) and (2,2)

Answers

Answer:

the equation to find the slope is (y2-y1)/(x2-x1)

the points are (-1,2) and (2,2) so plug it in and you get

(2-2)/(2-(-1))

0/ (2+1)

0/3

whenever the numerator is 0, that means the slope is 0. the line is just a horizontal line.
