The answer is 7 instead of 5
Answer:
The first sampling method is Convenient Sampling. It is biased sampling and it is not representative of a random sample.
The second sampling method is Systematic Sampling. If this method of sampling is drawn from the population, it is an efficiently randomized sampling method.
Let us review the given answers.
1. Both samples should be exactly the same.
INCORRECT
2. Neither sample will be representative.
Because the second sampling method can be random, this answer is
INCORRECT.
3. The first sampling method, ..., is the most representative,
INCORRECT
4. The second sampling method, ..., is the most representative.
CORRECT
Step-by-step explanation:

Combine like terms by adding their FACES (Coefficients)
1) 4c² - 4
2) 20m^4 + 6m
3) -6a³ - 19a² + 8a - 10
4) -10a² - 2b + 3ab³ + 4a²b² -5b^4 - 9a²b² - 12a³b + 15ab³ = -10a² - 2b + 18ab³ - 5a²b² - 12a³b - 5b^4
5) 5a³ - 5a²
Answer:
56
Step-by-step explanation:
Since you said in order, 5+5+6+7 is 23 and times 2 equals 46 and add 10 to 56, (5+5+6+7)x2+10=56
Best answer would be 4 out of 9 (4/9). This is in simplest form. To find probability in this form, find the amount of numbers less than ten (4), then put it over the amount of numbers in the list (9).
Hope this helped :)
