In a experiment, the probability that event A occurs is 5/9, the probability that event B occurs is 5/7, and the probability tha
Ymorist [56]

Answer:

52.5% probability that A occurs given B occurs

Step-by-step explanation:

Suppose we have two events, A and B, the conditional probability formula is:

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

In which

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

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

P(B) is the probability of B happening.

In this problem, we have that:

P(A \cap B) = \frac{3}{8}, P(B) = \frac{5}{7}

So

P(A|B) = \frac{P(A \cap B)}{P(B)} = \frac{\frac{3}{8}}{\frac{5}{7}} = 0.525

52.5% probability that A occurs given B occurs

8.4 + 0.18x = 0.32x
bogdanovich [222]

Answer:

  x = 60

Step-by-step explanation:

Perhaps you want the solution to this equation.

Subtract 0.18x from both sides:

  8.4 = 0.14x

Divide by the coefficient of x.

  8.4/0.14 = x = 60

Ccalculate the value of f(4) for this function. f(x) = -(x-7)+3 i know the anwser is f(4)=6 but how?
Tasya [4]

Answer:

See below

Step-by-step explanation:

we have f(x) = -(x-7) + 3

and we want to find f(4)

essentially, f(4) means that the input is 4 and to find the output we plug in the value of the input where ever x is and evaluate.

So for f(x) = -(x-7) + 3

To find f(4) we replace all x's with 4

f(4) = -(4-7) + 3

we now evaluate

==> subtract 7 from 4

f(4) = -(-3) + 3

==> apply two negative rule ( basically if there are two negative signs they cancel out and the number turn positive )

f(4) = 3 + 3

==> add 3 and 3

f(4) = 6
