Answer:
(x+1)^2 + (y-7)^2 = 2^2
Step-by-step explanation:
The center of the circle is at (-1,7) and the radius from the center to the edge is 2, so the equation should look like (x-h)^2 + (y-k)^2 = r^2
You would flip the signs of the center so that when you solve the equation it ends up in the correct place.
Answer:
125

To find the expected number of black marbles, take the probability of getting a black marble times the number of marbles drawn
P(black) * 200
5/8 *200
125
We should expect 125 black marbles
