If events A and B are independent, what must be true?A.) P(AB) = P(B)
anygoal [31]

Answer:

B.) P(A/B) = P(A)

Step-by-step explanation:

If two events, A and B are independent:

We have that:

P(A \cap B) = P(A)P(B)

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

Since they are independent:

P(A \cap B) = P(A)P(B)

Then

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)P(B)}{P(A)} = P(B)

So

P(B|A) = P(B), or either:

P(A|B) = P(A), and thus, the correct answer is given by option B.

This is very hard for me I need to know how to do it
insens350 [35]

The zeros of a function are the values of x that make the function be equal to zero.

When graphing a quadratic equation, the graph is a parabola, and the zeros of the function are the x-intercepts of the graph, which are the points where the graph intersects the x-axis.

So, if the zeros of this function are x = -8 and x = 2, that means the parabola crosses the x-axis at x = -8 and x = 2.

Therefore the correct option is the first one.

Find the 8th Term for the Geometric Sequence for which a1 - 3 and r = -2
Firdavs [7]

Answer:

-384

Step-by-step explanation:

geometric sequence : every new element is generated by multiplying the previous element always with the same number r.

a(n) = a(n-1) * r

a(n) = a(1) * r^(n-1)

so, a(1) = 3, r = -2

a(8) = ?

a(8) = a(1) * r^7 = 3 * (-2)^7

a negative number to an uneven power is again a negative number.

so, (-2)^7 = -128

3 * -128 = -384 = a(8)
