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?

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

the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.
x+(2x+15)+the measure of angle Q should equal 180.
Since everything is addition, the parenthesis can be removed.
x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.

Isolate x:
3x + 2 = 6x - 13
Subtract 3x from both sides:
2 = 3x - 13
Add 13 to both sides:
15 = 3x

4xy(y² + 2x)
When we have brackets like this, we multiply whatever is left of the brackets by everything inside.
1) 4xy multiplied by y²
4xy x y² = 4xy³
2) 4xy multiplied by 2x
4xy x 2x = 8x²y
3) Add together 4xy³ and 8x²y
4xy³ + 8x²y

Step-by-step explanation:
given that c is the midpoint of segment ab and ab = 20
Then ac is one half of ab
ac = × 20 = 10
Final answer:
In Geometry, a midpoint divides a line segment into two equal parts. So, if C is the midpoint of line segment AB with a total length of 20 units, the length of segment AC is 10 units.
Explanation:
The subject of this question is in the area of Geometry, specifically, it's about understanding the concept of a midpoint in a line segment. In a line segment AB, if C is the midpoint, it divides the line segment AB into two equal parts. So, if the total length of AB is 20 units, then the lengths of AC (from A to C) and BC (from B to C) are both equal to half of the total length. Hence, the length of segment AC is
10 units
. This is the concept of a midpoint which divides any given segment into two halves.
