Answer:
An outlier is defined as a data point that emanates from a different model than do the rest of the data. ... If the outlier is omitted from the fitting process, then the resulting fit will be excellent almost everywhere (for all points except the outlying point).
An outlier for a scatter plot is the point or points that are farthest from the regression line. ... If a number of points are the same farthest distance from the regression line, then all these points are outliers. If all points of the scatter plot are the same distance from the regression line, then there is no outlier.

A linear regression has a correlation coefficient of r=0.82
. Would this be a good correlation coefficient? What is the best value you could have for a correlation coefficient? Explain your reasoning completely.
Answer:
not very good
Step-by-step explanation:
the correlation should be almost 1 to be a good representation of the data. 0.82 isn't very close. This would be a pretty "rough" approximation at best. Maybe that's all that's needed but usually something close to 1.. like 0.99 is needed.
Which expression uses the associative property to make it
easier to evaluate 6(1/3•7/5)
O A. (6.1/3)7/5
O B. (6•5/7)1/3
O C. 6(7/5•1/3)
OD 3(1/6•7/5)
Answer:
A
Step-by-step explanation:
Here, we want to select which of the expressions correctly use the associative property
The associative property deals with rearrangement
So for (a + b) + c
we can have (a + c) + b
In the case of this question, the associate property is the one that makes the evaluation easier
Thus;
we need to bring 1/3 and 6 together since 3 is a factor of 6
We have;
(6•1/3)7/5
Find the measure of 1 in the figure, shown to the right.
Answer:
∠1 = 81°
Step-by-step explanation:
∠1 and 81° are corresponding angles and corresponding angles are equal to each other.
The measure of ∠1 in the figure is 81°.
What are Angles?Angles are the figure formed by the intersection of two lines or rays by sharing a common point. This point is called the vertex of the angle.
Angles are usually measured in degrees or radians.
Given is a figure of two parallel lines which is cut by a transversal line.
There are many properties for the angles formed by the transversal lines.
One of the property is that corresponding angles are equal.
Corresponding angles are the pair of angles which are on the same side of each parallel lines and at the same side of the transversal but at different intersections.
In the given figure,
∠1 and 81°, ∠3 and ∠7, ∠2 and ∠6, ∠4 and ∠8 are corresponding angles.
Since ∠1 and 81° are corresponding angles ∠1 = 81°.
Hence, measure of angle 1 is 81 degrees.

5+4(8n-8)=-1+6 for n
Answer:
n=1
Step-by-step explanation:
5+4(8n-8)=-1+6
5+32n-32=5
5+32n-32=5
-27+32n=5
32n=32
n=1
Answer:
n = 1
Step-by-step explanation:
5 + 4(8n - 8) = -1 + 6
First you have to distribute the 4 leaving the equation to look like this...
5 + 32n - 32 = -1 + 6
Now solve the constants (normal numbers without a variable)
-27 +32n = 5
+27 +27 You have to add 27 to BOTH sides
32n = 32
n = 1

The slope of line passing through M (-3,5) & N (1,8) will be 3/4.
We have been given a line passing through points M (-3,5) & N (1,8) .
We have to find out what will be the slope of the line ?
What is the formula for slope of a line ?
Slope of line is given by , m = (y2-y1) / (x2-x1).
Given that line is passing through points M (x1 , y1) and N (x2,y2) or M (-3,5) & N (1,8).
here , x1 = -3 , y1 = 5 , x2= 1 . y2 = 8
The slope (m) of line will be ;
∵ m = ( y2-y1) / (x2-x1)
m = ( 8-5) / (1- (-3))
m = 3 / 4

An equation is shown below:
4(x − 3) − 5(x + 1) = 3
Which statement shows a correct next step in solving the equation?
The equation can become 4x − 3 − 5x + 1 = 3 by applying the associative property of multiplication.
The equation can become 4x − 3 − 5x + 1 = 3 by applying the distributive property.
The equation can become 4x − 12 − 5x − 5 = 3 by applying the distributive property.
Answer:
The equation can become 4x − 12 − 5x − 5 = 3 by applying the distributive property.
Step-by-step explanation:
By applying the distributive law to this equation, we can produce the equation :
4x − 12 − 5x − 5 = 3;
The distributive property is a mathematical function in which each element in the parentheses is multiplied by the one outside of it;
4(x − 3) − 5(x + 1) = 3
In the equation;
4 distribute over the first parentheses and -5 over the second one;
So we expand;
4x - 13 - 5x -5 = 3
In distributive property, expansion simply takes place.

A basketball hoop has a
diameter of approximately
18 inches. What is the
circumference of the
basketball hoop?
The perimeter of the basketball hoop is 18π inches.
The circumference of a circle can be found using the formula:
C = πd
where C is the circumference and d is the diameter of the circle.
In this case, the diameter of the basketball hoop is approximately 18 inches. So we can plug this value into the formula to get:
C = π(18)
Using a calculator or approximating π to 3.14, we can evaluate this expression to get:
C ≈ 56.52 inches
Therefore, the circumference of the basketball hoop is approximately 56.52 inches.
