the answer is {a} because Mr Robertson already had the unit rate which is 72 and Ms Malloy had the unit rate for 2 miles so to find the unit rate for 1 miles you have to divide 126 by 2 which gives you 63 miles per an hour so Mr.Robertson drove the faster
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>."
Counting all of the lines, there is About 17
Answer:
x = 32/67 y = 36/67
Step-by-step explanation:
5x+3y = 4 ------1
14x-5y = 4 -------2
1×5 ; 25x+15y = 20 --------3
2×3 ; 42x-15y = 12 -------4
3+4 ; 67x = 32
x = 32/67
5×(32/67)+3y = 4
y = 36/37
