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:
x=44/9 or 4 8/9
Step-by-step explanation:
Answer:
2 × n - 1 = x
Step-by-step explanation:
for example:
500 + 30% equals 650. 30% of 500 equals 150.
Step-by-step explanation:
7^2+8^2=113
Then square root 113 which is 10.63 to 2.d.p
So x=10.63
