PLEASE AWNSER <br><br> Simplify negative 4 over 5 ÷ 3 over negative 2.
GarryVolchara [31]

Answer:

8/15

Step-by-step explanation:

The reason is because to multiply, you take the reciprocal of the fraction...

So

4/5/3/-2, right? So that's basically -4/5 ÷ 3/-2 so 4/5 * -2/3. The reciprocal of a fraction is literally just flipping it. Now, you know how to multiply, right?

-4/5 * -2/3 = (you can't simplify) 8 (negative times negative = positive) / 5*3

so 8/5*3 = 8/15. 8/15 is 0.53333, or you can just keep it as a fraction.

Given that a randomly chosen flight arrives on time, what is the probability that it arrives in Philadelphia (PHL)?
olga55 [171]

Using concepts of probability, it is found that there is a 4.7% probability that it arrives in Philadelphia (PHL).

<h3>What is a probability?</h3>
  • A <em>probability </em>is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • Over a large number of trials, a percentage can also represent the probability of  single event.

In this question, researching the problem on the internet, we have that over a large number of flights, of those which arrived on time, 4.7% of them were in Philadelphia, hence:

  • There is a 4.7% probability that it arrives in Philadelphia (PHL).
