The two events are independent, because the selection of the first color (red) does not modifiy the probabilities of the second color (orange). Then the combined probability is the product of the two independent events:
1/7 * 1/7 = 1 / 49
Answer: option C. 1/49
Circle equation:
(x-a)^2 + (y-b)^2 = r^2
x^2 - 2ax + a^2 + y^2 - 2by + b^2 = r^2
x^2 + y^2 + a^2 + b^2 - 2ax - 2by - r^2 = 0
_______________________
4x^2 + 4y^2 + 36y + 5 = 0
4x^2 + 4y^2 + 36y + 5 +0x + 0y = 0
(-2ax = 0x)
-2a = 0
a = 0
(-2by = 0y)
-2b = 0
b = 0
____________________
And now:
a^2 + b^2 - r^2 = 5
0^2 + 0^2 - r^2 = 5
0+0-r^2 = 5
r^2 = -5
Since there is no negative radius, we say that it is not an equation of a circle
The answer is 120. Because inscribed angle is Half of the arc measure. Double 60 and we get 120.
Answer:
It's 2^5
Step-by-step explanation:
2*2*2*2*2=32
2^5=32
