it is a relatively easy way to draw a sample while ensuring randomness is the answer.
Systematic sampling is a probabilistic sampling method in which a researcher selects members of a population at regular intervals. For example, select every 15 people from the list of populations. If the population is in random order, this can mimic the benefits of a simple random sample.
These are generally preferred by researchers because they are easy to implement and understand. The important assumption that the results represent the majority of the normal population ensures that the entire population is sampled equally. The process also provides a higher level of control for systematic sampling compared to other sampling methods. systematic sampling also has a lower risk factor because the data is unlikely to be contaminated.

Answer:
The hotel charge in city one before tax is $3750 and the hotel charge in city two before tax is $2250.
tep-by-step explanation:
Let a = the charge in 1st city before taxes
Let b= the charge in 2nd city before taxes
Based on the information given . We can have the following equation (1).
y = x - 1500 ......(1).
Interms of the information given , the following is formulated based on taxed paid .
0.065x + 0.06y = 378.75 .....(2).
Now we substitute equation (1) into (2).
0.065x + 0.06(x - 1500) = 378.75
0.065x + 0.06x - 90 = 378.75
0.125x - 90 = 378.75
0.125x = 468.75
Therefor x=3750
Now x value into equation (1)
y = 3750 - 1500
y = 2250
The hotel charge in city one before tax is $3750 and the hotel charge in city two before tax is $2250.
<em>I think the best answer is:</em>
Explanation Below.
This is a proper fraction once the absolute value of the top number or numerator (4) is smaller than the absolute value of the bottom number or denomintor (52).
The fraction 
can be reduced.
We will use the Greatest Common Factor (GCF) method to simplify it.
The GCF is the largest number between which two or more numbers can be divided evenly.
To find the GCF we list the the numerator and denominator factors (*) then we find the largest number that is repeated in both lists:
* The factors of 4 are 1,2,4;
* The factors of 52 are 1,2,4,13,26,52.
We can see that the GCD is 4 because it is the largest number by which 4 y 52 can be divided without leaving any residue.
To reduce this fraction, simply divide the numerator and denominator by 4 (the GCF).
So, 
÷
-------------------------
÷ ≈
The factors are numbers that multiply each other to get another number. For example, 2 and 3 are factors of 6, because by multiplying them you get 6.
