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}

Lim x-> 0 sqrt x+4 -2 / x
Wittaler [7]

Greetings from Brasil...

Here we have an indeterminacy 0/0

We can change variable or rationalize.......

Let's rationalize

{[√(X + 4) - 2]/X} · {[√(X + 4) + 2]/[√(X + 4) + 2]} = 1/[√(X + 4) + 2]

So, the limit will be 1/4

aleksley [76]

Answer:

Step-by-step explanation:

z  value of 14.9  = (16.3 - 14.9) / 2

= 0.7

= .7580

z  value of 12.9  = (16.3 - 12.9) / 2

= 1.7

=.9554

Required probability = .9554 - .7580

= .1974

Solve the inequality and enter your solution as an inequality comparing the variable to the solution in the box below. 18 + x &g
storchak [24]

<em><u>Hi there! :)</u></em>

<em><u>Answer:</u></em>

<em><u>x>24</u></em>

<em><u>*The answer must have a positive sign and greater than symbol sign.*</u></em>

<em><u>Step-by-step explanation:</u></em>

First, you switch sides.

x+18>42

Then, you subtract by 18 from both sides of an equation.

x+18-18>42-18

Finally, you subtract by the numbers from left to right.

42-18=24

<u><em>Final answer is x>24</em></u>

I hope this helps you!

Have a nice day! :)
