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.
Answer:
The remainder is 5
Step-by-step explanation:
Take out the variable to add the numbers because it is the same variable throughout so 6-5+7=8 then add the n^2 o get 8n^2
Answer:
a. x > 0.2
Step-by-step explanation:
In either order, subtract the left-side constant and divide by the x-coefficient.
3x +2.4 > 3
3x > 0.6 . . . . . . subtract 2.4
x > 0.2 . . . . . . . divide by 3
__
or
x + 0.8 > 1 . . . . divide by 3
x > 0.2 . . . . . . . subtract 0.8
Answer:
B. (-5/13, 12/13)
Step-by-step explanation:
The point at distance x from π in the clockwise direction is the reflection of point T across the y-axis. Hence the coordinates are the same, except that the sign of the x-coordinate is reversed.
The point of interest is (-5/13, 12/13).
