PLEASE HELP ME!!!!!!!

Mathematics
1 answer:
Evgen [1.6K]2 years ago
3 0

Answer:

2/3

Step-by-step explanation:

p(B/A)=[P(A&B)]/p(A)

2/3=[P(A&B)]/(1/2)

P(A&B)=2/3 *1/2=1/3

P(A&B)=P(A)*P(B)

1/3=1/2*P(B)

P(B)=1/3*2/1=2/3

Explain the step(s) needed to solve 4+ p = 1 and then solve for p
liberstina [14]

Answer:

p = -3

Step-by-step explanation:

Apply algebra to the equation by subtracting 4 from each side, that way it will cancel out at least the 4 next to p. It should now look like this: p = -3

Because we can't make anymore moves and the expression clearly states what p is, we're done!

Find the discriminant, describe the types of roots, and find the solution for 3x^2-24x+12
solniwko [45]
The discriminant of a polynomial is given by:
 b ^ 2-4ac
 Substituting the values we have:
 (-24) ^ 2-4 * (3) * (12) = 432
 Since the discriminator is greater than zero, then the roots are real.
 x = (- b +/- root (b ^ 2-4ac)) / (2a)
 Substituting the values:
 x = (- (- 24) +/- root (432) / (2 * (3))
 x = (- (- 24) +/- root (432) / (2 * (3))
 x = (- (- 24) +/- root (144 * 3) / (2 * (3))
 x = (24 +/- 12raiz (3) / (6)
 x = 4 +/- 2raiz (3)
 The roots are:
 x1 = 4 + 2raiz (3)
 x2 = 4 - 2raiz (3)
 Answer: 
 432
 the roots are real.
 
x1 = 4 + 2raiz (3)
 
x2 = 4 - 2raiz (3)

Answer:

A

Step-by-step explanation:

The easiest way to simplify the expression below is using a property: if we take random non-0 number  to the 0 power, we finally get 1, so a^0=1
