Answer:

0.0286 or 2.86%

Step-by-step explanation:

The total number of people that have werewolfism is 21,000.

Of those 21,000, 600 also have vampirism, while the remaining 20,400 do not. Therefore, the probability that someone has vampirism, given that they have werewolfism is:

P(V|W)=\frac{N_{V\cap W}}{N_W}\\P(V|W)=\frac{600}{21,000} \\P(V|W)=0.0286=2.86\%

The probability is 0.0286 or 2.86%.

Solving a Quadratic Equation by Completing the Square Solve x2 + 8x = 33 by completing the square. Which is the solution set of
tresset_1 [31]
Divide the coefficient of x by 2 then square the quotient.
Add the result to both sides of the equation.

x^2 + 8x = 33
x^2 + 8x + (\frac{8}{2})^2 = 33 + (\frac{8}{2})^2
x^2 + 8x + 4^2 = 33 + 4^2
x^2 + 8x + 16 = 33 + 16
x^2 + 8x + 16 = 49

Factor the left-hand side.

(x + 4)^2 = 49

Square both sides.

x + 4 = \sqrt{49}

Subtract both sides by 4.

x = -4± \sqrt{49}

Simplify.

x = -4± 7
So, x can either equal -4 + 7 or -4 - 7

So, the answer is {-11, 3}

NOTE: You're probably seeing a strange A in the equations. I tried to fix it, but I couldn't. Sorry about that.
