You can do this by completing the square on x and y terms:
x^ - 10x + y^2 + 6y + 18 = 0
(x - 5)^2 -25 + (y + 3)^2 - 9 + 18 = 0
(x - 5)^2 + (y + 3)^2 = -18 + 9 + 25 = 16
so radius = sqrt16 = 4 answer
You have to make the mixed number into a fraction in order to divide
Answer:
0.321 (Answer D)
Step-by-step explanation:
Note that the event "A and Y" happens 9 times. That's 9 times out of (6+9+8+5) outcomes, or 28 outcomes.
Hence, P(A and Y) = 9/28, or 0.321 (Answer D)
It is 555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555555
