Answer and explanation:
A negative correlation means a relationship between two variables whereby each variable affects the other such that an increase in one variable means a decrease in the other and vice versa. This is the situation with the correlation graph/scatter plot of Dr. Hotchkins: An increase in stress would cause a decrease in emotional well being and vice versa
An Outlier is a data point on the scatter plot that does not fall into the pattern of the correlation graph. From the above, 4 points are outliers: extremely high points on stress and emotional well being. These points would affect (increase or decrease) the correlation coefficient depending on where they fall in the pattern. In this case there are 4 outliers out of 60 data points and we know that the more outliers there are the more effect they have on the correlation coefficient and vice versa(also depending on where the outlier is on the scatter plot)
Answer:
Step-by-step explanation:
50 - x² = 0
50 = x²
x² = 50
x = √50
Answer:
24 sides
Step-by-step explanation:
Angle at a point = 360°
To find the number of degrees in each interior angle of a regular polygon, we make use of
180(n - 2)/n
There are 8 sides in a regular octagon,
Each interior of a regular octagon= 180(8-2)/8
= 6 * 180/8
= ¾ * 180
= 135°
The interior angle of a regular triangle (equilateral triangle) is 60°
The interior angle of the regular n-gon is given by
360° - 135 - 60°
= 165°
Since the interior angle is 165°
Then
180(n - 2)/n = 165 for the regular n-gon
Solving for n
Multiply both sides by n
180(n - 2) = 165n ------ Open the bracket
180n - 360 = 165n ----- Collect Like Terms
180n - 165n = 360
15n = 360 ----- Divide both sides by 15
n = 360/15
n = 24
Thus, the number of sides of the regular n-gon is 24
