Answer:
Step-by-step explanation:
I am solving this using Function Notation.
We are given:
While we are to find:
In Function Notation, replace all the "
" you see with the value you are given.
So, in this case,
Would become
Now we can solve.
Use PEMDAS; Parenthesis first;
Cross divide: 1 cancels 1, -4 ÷ 2 = -2
Hence, we are left with
Therefore, the value of x is -5

Step-by-step explanation:
You take 30.16 and divide that by 8 which equals 3.77
have a nice day! :)
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.
