By selecting a regression specification based on R2 a, a researcher implicitly adopts which of the following principles explain as little of the variation in y using as many xi as possible.
<h3>What does R² value tells you?</h3>
R² value provides an estimate of the relationship between the motion of the dependent variable, which depends on the movement of the independent variable in the equation.
The linear regression equation can be given as,
Here, Y is dependent variable and X is independent variable. Using the regression equation, it is see that how much Y value changes when we change the value of X.
Variation is the distribution of the value of Y, which is little for the different xi possible.
Thus, by selecting a regression specification based on R2 a, a researcher implicitly adopts which of the following principles explain as little of the variation in y using as many xi as possible.

Answer:
5:9
Step-by-step explanation:
20÷4=5
36÷4=9
If you divide 20 by 4 you get 5. If you divide 36 by 4 you get 9. You need to be able to divide each number in the ratio by the same number. In this case, that number is 4. You can tell that this ratio (5:9) is in simplest form because 5 is a prime number and cannot be simplified any more.
If you want to check this divide the ratio by 2 two times. Or just divide it by 4 once.
20÷2=10 → 10÷2=5
36÷2=18 → 18÷2=9
Answer:
10
Step-by-step explanation:
I got it right
3x + 3y + 2z = -5 ⇒ 3x + 3y + 2z = -5 ⇒ 3x + 3y + 2z = -5
1x + 1y + 3z = -4 ⇒ 1x + 1y + 3z = -4 ⇒ 3x + 3y + 9z = -12
3x - 1y + 5z = -8 -7z = 7
-7 -7
z = -1
3x + 3y + 2z = -5
1x + 1y + 3z = -4 ⇒ 1x + 1y + 3z = -4
3x - 1y + 5z = -8 ⇒ 3x - 1y + 5z = -8
4x + 8z = -12
4x + 8z = -12
4x + 8(-1) = -12
4x - 8 = -12
+ 8 + 8
4x = -4
4 4
x = -1
3x + 3y + 2z = -5
3(-1) + 3y + 2(-1) = -5
-3 + 3y - 2 = -5
3y - 3 - 2 = -5
3y - 5 = -5
+ 5 + 5
3y = 0
3 3
(x, y, z) = (-1, 0, -1)
