Your question is really hard to read, but I'll give my best to give you an appropriate answer.
Generally, a sample which best represents the population would usually be one which makes it equally likely for everyone to be included into that sample.

observing every person walking down Main Street at 5 p.m. one evening to determine the percentage of people who wear glasses

and measuring the heights of every fiftieth person on the school roster to determine the <span>average heights of the boys in the school calling every third person on the soccer</span><span> </span>
Are surely two. It is questionable if any of the other ones are really randomized and represent the population fairy well or not.
Answer:
The equation of the linear function represented in the table is y = -4x + 1.
Explanation:
Since the values in the x-variable are consecutive, let's take a look at the y-values.
Let's determine the common difference of the y-values.
As we can see, the common difference between the y-values is -4. Therefore, the slope of the equation is -4.
To determine the y-intercept, let's subtract -4 from -3 to determine the y-value at x = 0.
Hence, the y-intercept is 1.
Therefore, the equation is y = -4x + 1.
72 orders in 3 days
that means
In 3 days, the number of orders = 72
Now to find the number of orders per day, i.e number of orders in 1 day
for this divide the total number of orders with the number of days
Thus, there are 24 orders per day
Answer : 24 orders per day
There would be about 27663 cars going through a year
