Answer:
x=30
Step-by-step explanation:
The two angles are on a straight line, so they are supplementary. They add to 180 degrees.
4x+20+40=180
Combine like terms
4x+60=180
Subtract 60 from both sides
4x+60-60=180-60
4x=120
Divide both sides y 4
4x/4=120/4
x=30
Answer:
The assumption of homoscedasticity is that "<u>the variability of Y doesn't change over the X scores</u>."
Step-by-step explanation:
The assumptions of linear regression are:
- Linear relationship
- Multivariate normality
- Almost 0 mulitcollinearity
- 0 Autocorrelation
- Homoscedasticity
The assumption of homoscedasticity implies that the variance of the dependent variable <em>Y</em>, across the regression line does not changes for all values of the predictor variable <em>X</em>.
Thus, the complete statement is:
The assumption of homoscedasticity is that "<u>the variability of Y doesn't change over the X scores</u>."
