Answer:
x - 4 = 4x
4x × 5 = 20x
20x + 9 = 29x
Step-by-step explanation:
1=5-4 because you have to substitute x and y (x,y) or (5,1)
Step-by-step explanation:
9x2+5x4
= 18 + 20
= 38
the answer is 38
Answer:
The regression line is not a good model because there is a pattern in the residual plot.
Step-by-step explanation:
Given is a residual plot for a data set
The residual plot shows scatter plot of x and y
The plotting of points show that there is not likely to be a linear trend of relation between the two variables. It is more likely to be parabolic or exponential.
Hence the regression line cannot be a good model as they do not approach 0.
Also there is not a pattern of linear trend.
D) The regression line is not a good model because there is a pattern in the residual plot.
