The equation of a circle uses the following formula:

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

The center of the circle is given by (h,k). Therefore, h = -2, and k = -5. r = 1, so we can find the equation from the information given to us.

Plug in your values.

$(x + 2)^{2} + (y + 5)^{2} = 1^{2}$

$1^{2} = 1$

The equation of this circle is as follows:

$(x + 2)^{2} + (y + 5)^{2} = 1$

A bag contains 30 lottery balls numbered 1-30 a ball is selected replaced then another is drawn find each probability

iogann1982 [59]

#1) 5/20
#2) 7/300
#3) 3/50
#4) 5/20

Explanation
For #1:
There are 15 even numbers out of 30. Since it is replaced before drawing the second ball, there will be 15 odd numbers out of 30. This gives us
15/30(15/30) = 225/900 = 5/20.

For #2:
There is 1 7 out of 30; then there are 14 numbers greater than 16 out of 30:
1/30(14/30) = 14/900 = 7/300

For #3:
There are 6 multiples of 5 out of 30; then there are 9 prime numbers out of 30:
6/30(9/30) = 54/900 = 3/50

For #4:
There are 15 even numbers out of 30; then there are still 15 even numbers out of 30:
15/30(15/30) = 225/900 = 5/20
