1. r closest to 1: Figure 4
2. Least signs of linear relationship: Figure 1
3. r equal to -1: Figure 3
Step-by-step explanation:
Correlation is the link between two things or variables.
The scatter plots can be used to determine the correlation values for given sets of data.
If both values are increasing, then the correlation is positive
If one value is increasing and the other is decreasing then the correlation is negative
So,
In the given pictures
Figure 4 has the correlation coefficient closest to 1 as both values are increasing but the data points are not in a straight line so r will be close to 1.
Figure 3 has the correlation coefficient equal to one as one value is increasing and the other is decreasing. And the points are in a straight line so r will be equal to one.
As the data points in Figure 1 are more scattered so there will be no relationship between two quantities.
So, the answers are as follows
1. r closest to 1: Figure 4
2. Least signs of linear relationship: Figure 1
3. r equal to -1: Figure 3

To find the output when you know the input, just plug the input into the function.
x+21=4+21=25
The output is 25.
Hope this helps!
Answer:
188.60
Step-by-step explanation:
It is 188.60 since if you divide 754,40 by four you get 188.60
Answer:
It has to be in ax^2 + bxy + cy^2
Step-by-step explanation:
It has to be in ax^2 + bxy + cy^2
<span>An outlier of a set of data is a data value that is too small or too large compared to other values in the set of data.
Range of a set of data is the difference between the largest data value and the smallest data valu in the set of data.
Range of 23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78 is 78 - 23 = 55
When the outlier 78 is removed, the range of the data set 23, 23, 25, 27, 34, 34, 35, 41, 45, 45 is 45 - 23 = 22
Thus, when the outlier 78 is removed, the range of the data set decreases by 55 - 22 = 33.
Therefore, the correct answer to the question "The outlier, 78, is removed from the data set shown.
23, 23, 25, 27, 34, 34, 35, 41, 45, 45, 78
How does this affect the range?" is "The range is decreased by 33." (option D).</span>
