At LaGuardia Airport for a certain nightly flight, the probability that it will rain is 0.14 and the probability that the flight
morpeh [17]

Answer:

The appropriate answer is "0.437".

Step-by-step explanation:

Given:

P(rain) = 0.14

then,

P(no-rain) = 1-P(rain)

                 = 1-0.14

                 = 0.86

P(delay) = 0.16

P(rain and on time) = 0.79

then,

By using the conditional probability, we get

⇒ P(A|B)=\frac{P(A \cap B)}{P(B)}

or,

⇒ P(no \ rain|delay) = \frac{P(no \ rain \cap delay)}{P(delay)}

By substituting the values, we get

⇒                             =\frac{0.07}{0.16}

⇒                             =0.437

3x - 14 + 4 + 2x + (-18 + 3x)=180
Helen [10]
Answer: x=26

Let’s start with rewriting the equation

3x-14+4+2x+(-18+3x)=180

Now let’s distribute. We’ll do this by multiplying the 1 with the -18, and the 1 with the 3x.

3x-14+4+2x+(-18+3x)=180

3x-14+4+2x-18+3x=180

Now let’s combine like terms. These are the numbers that share the same variable, or lack of.

3x-14+4+2x-18+3x=180

8x-28=180

Our goal is to get x alone on the left side. Our first step in doing this is to add 28 on both sides.

8x-28=180
+28 +28
_________
8x=208

Now to finally get x alone on the left side (and get our final answer) we need to divide 8x and 208 by 8.

8x=208

8x/8=208/8

x=26

This is the final answer!
