Answer:
<h2>{5}</h2>
Step-by-step explanation:

Digit numbers.
Let the numbers 00 to 89 represent that the train is on time.
Let the numbers between 90 and 99 represent that the train is late.
Randomly select 6 numbers, with repetition allowed.
Count the number of times the train is late.
Repeat this simulation multiple times.
You will most likely obtain a result of between 0 and 2 times that the train is late.

If you add $15 + $27 because that's how much it costs for each student, you get $42. Then you divide $714 by $42, you get 17 and that's how many students are in the class this month.
<span>If the range of the answer should be +/- 10% of the particular value, then you have to solve for the percentage of that particular value. Since the value given is 1.8, we thus want to find 10% of that:
1.8 * 10/100 = 0.18
Then, add this value to the original value of 1.8:
1.8+0.18 = 1.98
Next, subtract .18 from from the original value of 1.8:
1.8-0.18 = 1.62
The range will be between these two numbers, so the range is from 1.62 to 1.98.</span>
