Answer:
B: 0.20
Step-by-step explanation:
Green was selected 8 of the 40 times. We expect its probability of selection to be about ...
8/40 = 1/5 = 0.20 . . . p(green)
If A is parallel to B and B Is perpendicular to Y
⇒A is perpendicular to Y (Option D)

All you have to do is divide 20 by 12.5
The equation of a circle is written as ( x-h)^2 + (y-k)^2 = r^2
h and k is the center point of the circle and r is the radius.
In the given equation (x+3)^2 + (y-1)^2 = 81
h = -3
k = 1
r^2 = 81
Take the square root of both sides:
r = 9
The center is (-3,1) and the radius is 9
