The general formula for a circle with center (a,b) and radius r is
If we know the center and a point on the circle, the squared radius is given by substituting in the point for x and y.
Answer:
Answer:
Probability of no black bead is adjacent to the yellow bead is = 0.966
Step-by-step explanation:
First to arrange all the beads without restrictions = 6! = 720
Probability the black bead is adjacent to Yellow bead = 4!/6! = 24 /720
= 0.0333
Probability of no black bead is adjacent to the yellow bead is
= 1- Probability the black bead is adjacent to Yellow bead
= 1-0.033
= 0.966
2/216 = 7/x
cross multiply
(2)(x) = (216)(7)
2x = 1512
x = 1512/2
x = 756 <==
Answer:
0.75x-18.50=0.65x
0.65x-0.75x=-18.50
-0.10x=-18.50
x=0.0054054054
