The best answer from the options that proves that the residual plot shows that the line of best fit is appropriate for the data is: ( Statement 1 ) Yes, because the points have no clear pattern
X Given Predicted Residual value
1 3.5 4.06 -0.56
2 2.3 2.09 0.21
3 1.1 0.12 0.98
4 2.2 -1.85 4.05
5 -4.1 -3.82 -0.28
The residual value is calculated as follows using this formula: ( Given - predicted )
1) ( 3.5 - 4.06 ) = -0.56
2) ( 2.3 - 2.09 ) = 0.21
3) ( 1.1 - 0.12 ) = 0.98
4) (2.2 - (-1.85) = 4.05
5) ( -4.1 - (-3.82) = -0.28
Residual values are the difference between the given values and the predicted values in a given data set and the residual plot is used to represent these values .
attached below is the residual plot of the data set
hence we can conclude from the residual plot attached below that the line of best fit is appropriate for the data because the points have no clear pattern ( i.e. scattered )

Answer:
225 words
Step-by-step explanation:
In order to find the answer to this question we have to find how many words she writes in 1 minute. To do this you need to divide 90 words by 4 minutes:
(90)/4 = 22.5 words/minute
Now that the words per minute is found, we can multiply it by the 10 minutes to find how many words she can write in 10 minutes:
(22.5)(10) = 225
Therefore, Sara can type about 225 words in 10 minutes.

Answer:
Step-by-step explanation:
f(x)=-2(x+3)²-3
it is a downward parabola with vertex (-3,-3)
when x=-3,f(x)=0-3=-3
for all other value f(x) ≤ -3
maximum value =-3 at -3
