F(2)=4+10-8=6; f(6)=36+30-8=58. Average rate of change is (58-6)/(6-2)=52/4=13
Add 15 to both sides
Y = -27 + 15
Y = -12
Step-by-step explanation:
12 to the 2nd power=144
15 to the 2nd power =225
225-144=81
square root of 81 is 9

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).
