Answer:
Step-by-step explanation:
Hello!
The objective of this experiment is to assess the service customers receive at the dealerships.
1) The population in this survey is:
The population is the customers of car dealerships.
2) The sample in this survey is:
The random sample taken was 20 selected car dealerships, where the customers were surveyed.
3) A parameter that may be targeted by the survey is:
To study the service the customers receive at the dealerships and if it has any influence in the customers owning or not a car of the company, one parameter to study is the population proportion of customers that own a car of the company vs the proportion of customers that are satisfied with the service received.
4) A statistic that may be used to summarize the outcome of the survey is:
The statistic to use to summarize the outcome of the survey is the sample proportion.
I hope it helps!

Answer:
C) 3(x+7)²
Step-by-step explanation:
<h3>Answer:</h3>
- f(1) = 2
- No. The remainder was not 0.
<h3>Explanation:</h3>
Synthetic division is quick and not difficult to learn. The number in the upper left box is the value of x you're evaluating the function for (1). The remaining numbers across the top are the coefficients of the polynomial in decreasing order by power (the way they are written in standard form). The number at lower left is the same as the number immediately above it—the leading coefficient of the polynomial.
Each number in the middle row is the product of the x-value (the number at upper left) and the number in the bottom row just to its left. The number in the bottom row is the sum of the two numbers above it.
So, the number below -4 is the product of x (1) and 1 (the leading coefficient). That 1 is added to -4 to give -3 on the bottom row. Then that is multiplied by 1 (x, at upper left) and written in the next column of the middle row. This proceeds until you run out of numbers.
The last number, at lower right, is the "remainder", also the value of f(x). Here, it is 2 (not 0) for x=1, so f(1) = 2.
