Answer:

(x+4)^2 +(y+6)^2 = 9

Step-by-step explanation:

The equation for a circle is given by

(x-h)^2 + (y-k)^2 = r^2

Where (h,k) is the center and r is the radius

(x- -4)^2 + (y--6)^2 = 3^2

(x+4)^2 +(y+6)^2 = 9

Answer:

(x + 4)2 + (y + 6)2 = 9 is the equation of this circle.  

Step-by-step explanation:

The standard equation of a circle with center (h, k) and radius r is

(x-h)^2 + (y-k)^2 = r^2.  Please use " ^ " for exponentiation.

We can immediately discard the 1st and 3rd answers, since the radius squared is 3^2, or 9.

Comparing

(x -  h)^2 + (y-k)^2 = r^2 to

(x + 4)2 + (y + 6)2 =    9 shows that h = -4 and k = -6, as well as r = 3.

Therefore, (x + 4)2 + (y + 6)2 = 9 is the equation of this circle.

Answer: You have a better chance if you do not replace the red marble.

Step-by-step explanation:

The bag has:

5 red marbles

8 blue marbles

4 yellow marbles

3 green marbles

A total of 5 + 8 + 4 + 3 = 20

You want to draw a red marble and then a blue marble.

The probability of drawing a red marble in your first attempt is the number of red marbles divided the total number of marbles:

P1 = 5/20  

now you want to draw a blue marble.

If you replace the red marble, you have 20 marbles again in the bag, then the probability of drawing a blue marble is:

P2 = 8/20

The joint probability is P = P1*P2 = (5/20)*(8/20) = 0.1

If you do not replace the red marble, you have 19 total marbles in the bag, then the probability of taking a blue marble is:

P2 = 8/19

The joint probability is:

P = P1*P2 = (5/20)*(8/19) = 0.105

The probability is slightly bigger if you do not replace the red marble.
