Given:
Right triangle with one angle 45°
To find:
The value of q and r.
Solution:
Opposite to θ = 16
Adjacent to θ = r
Hypotenuse = q
Using trigonometric ratio formula:
The value of tan 45° = 1
Do cross multiplication, we get
r = 16
Using trigonometric ratio formula:
The value of sin 45° = .
Do cross multiplication, we get
The value of r is 16 and the value of q is .
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>."
Answer:
Perimeter of triangle= sum of two sides and hypotenuse
