9n - 6 = 5n + 18<br> Solve

IgorLugansk [536]

Answer:

n = 6

Step-by-step explanation:

9n - 6 = 5n + 18

Subtract 5n from each side

9n-5n - 6 = 5n-5n + 18

4n -6 = 18

Add 6 to each side

4n -6+6 = 18+6

4n = 24

Divide each side by 4

4n/4 = 24/4

n = 6

According to the general equation for conditional probability, if (image attached)

katrin2010 [14]

Answer: Option A

$P(A|B) = \frac{40}{49}$

Step-by-step explanation:

In a probabilistic experiment, when two events A and B are dependent on each other, then the probability of occurrence A since B occurs is:

$P(A|B) = \frac{P(A\ and\ B)}{P(B)}$

Then if $P(A\ and\ B) = \frac{5}{7}$ and $P(B) = \frac{7}{8}$ then:

$P(A|B) = \frac{\frac{5}{7}}{\frac{7}{8}}\\\\P(A|B) = \frac{40}{49}$
