Answer:a) 5 sides
b) 9 sides
Step-by-step explanation:
a) Since the polygon is a regular polygon, all the interior angles are equal. If one exterior angle is 72 degrees, the interior angle would be
180 - 72 = 108 degrees(sum of the angles on a straight line is 180 degrees)
The sum of the interior angles of a polygon is expressed as
180(n - 2)
Where n represents the number of sides that the polygon has. Since the interior angles are equal, then
108n = 180(n - 2)
108n = 180n - 360
180n - 108n = 360
72n = 360
n = 360/72 = 5
b) If one exterior angle is 40 degrees, the interior angle would be
180 - 40 = 140 degrees
Since the interior angles are equal, then
140n = 180(n - 2)
140n = 180n - 360
180n - 140n = 360
40n = 360
n = 360/40 = 9
Answer:
Step-by-step explanation:
Residual value the difference between the observed value of the dependent variable and the predicted value is called the residual.
Residual , 
, where R is the residual value, O, is the observed value, and P is the predicted value. The sum and the mean of the residuals are equal to zero.
Now, we can see that the biggest <em>magnitude </em>of the difference is of 
and is at the point . (
)
Therefore, the point farthest from the line of best fit is the one whose magnitude of residual value is the most and in this case that point is .
-15-(-18)=-15 +(-18)=-33
-×-=+ +×-= -
-15×-(-18)= 3
-15×+(-18)=-33
3-33=-33
-30=-30
Answer:
I think it would be 17 because 34 ÷ 2 = 17
