Answer:
No real solution
Step-by-step explanation:
First off I'm assuming that the 1 or -1 at the begging is just the problem number:
First you distribute on both sides
36 - 18x - 3 = 4 - 18x + 30
Then combine like terms
33 - 18x = 34 - 18x
Then rearrange the terms by adding 18x to both sides and subtracting both sides by 33. You should get:
0 = 1
When you add positive 18x it cancels the -18x out. And 34 - 33 is 1. Obviously, zero cannot equal 1 so there is no real solution
Answer: A: $1.45
Work:
$2:49 divided by 12 = 0.2075
0.2075 x 7 = 1.4525
1.4525 = 1.45
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.
