Step-by-step explanation:
-one angle is always 90°
-The side opposite angle 90° is hypotenuse
-hypotenuse is the longest side
-the sum of other 2 interior angles is 90°
-area of right angled triangle is 1/2×base×height
The equation of a circle is:
(x-h)2 + (y-k)2 = r2
where (h,k) is the location of the center and r is the radius. So we need to find h, k, and r. The center is given as (5,-4) so h = 5 and k = -4:
(x-5)2 + (y-(-4))2 = r2
(x-5)2 + (y+4)2 = r2
So we need to find r. Use the distance formula to find the distance between (5,-4) and (-3,2):
r = [(5-(-3))2+((-4)-2)2]1/2
r = [82 + (-6)2]1/2
r = [64 + 36]1/2
r = 1001/2
r= 10
The final equation is:
(x-5)2 + (y+4)2 = 102
X^2 - 6x = 20
x^2 - 6x + 9 = 20 + 9
(x - 3)^2 = 29
x - 3 = (+-) sqrt 29
x = 3 (+-) sqrt 29
x = 3 (+-) 5.39
x = 3 + 5.39 = 8.39 <=
x = 3 - 5.39 = - 2.39 <=
Answer:
Skewed Left
Option 1 is correct.
Step-by-step explanation:
We have been given a graph
The given graph is not uniform since there is change in graph that is it is not continuously distributed
The given graph has a tail or the longer side on its right
Hence, it is the left skewed graph
Because skewed left graph is the one in which tail is on the right side.
And skewed right is the one in which tail is on the left hand side.
Therefore, Option 1 is correct.
An outlier causes the median to move slightly towards the outlier.
