Answer:
D
Explanation:
6/ 1/2 = 6*2, 6*2 not equal to 3
half of 8 is 4, not 16
1/2+2 = 2 1/2
10/ 1/2 = 10*2 = 20
6400 hope it workks
square 80 is the answer
Answer:
(0, -3)
Step-by-step explanation:
Here we'll rewrite x^2+y^2+6y-72=0 using "completing the square."
Rearranging x^2+y^2+6y-72=0, we get x^2 + y^2 + 6y = 72.
x^2 is already a perfect square. Focus on rewriting y^2 + 6y as the square of a binomial: y^2 + 6y becomes a perfect square if we add 9 and then subtract 9:
x^2 + y^2 + 6y + 9 - 9 = 72:
x^2 + (y + 3)^2 = 81
Comparing this to the standard equation of a circle with center at (h, k) and radius r,
(x - h)^2 + (y - k)^2 = r^2. Then h = 0, k = -3 and r = 9.
The center of the circle is (h, k), or (0, -3).
I think is 22
sorry if i'm wrong
Answer:
The answer is 0.367. The total possibilities of choosing 10 players is C₁₃¹°=C₁₃³=13*12*11/(3*2*1). The possibilities of choosing 4 girls and 6 boys is C₆⁴ * C₇⁶ = C₆² * C₇¹ = 6*5/2 * 7. So the probability is 0.367.(possibility of first divide by the second)
