You pay off the bigger one first because if you don't do that one first the amount of money in the credit card will just gain interest and have more, and you won't be able to pay the big amount.
X=13/15. Subtract 8x from both sides to get 3x=13/5. Divide both sides by 3 or multiple both sides by 1/3 to get x=13/15.

Answer:
10.69% probability that all 12 flights were on time
Step-by-step explanation:
For each flight, there are only two possible outcomes. Either it was on time, or it was not. The probability of a flight being on time is independent of any other flight. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
83% of recent flights have arrived on time.
This means that 
A sample of 12 flights is studied.
This means that 
Calculate the probability that all 12 flights were on time
This is P(X = 12).


10.69% probability that all 12 flights were on time
627 is the answer because I just added 229 and 398 because it only gives us those two numbers that are useful
