Answer:
B. 20÷10=2
Step-by-step explanation:
Well , A and C can not answer 2×10 = 20 , whatever , even have not make the equation correct .
Correct A. 2÷10=2/10=0.2 Even have a correct, still can not answer why 2×10 = 20
_______________________________ (1). 2÷10 ≠ 20 ( Proof )
B. 20÷10=2 This a correct answer (1). 20÷10 = 2 ( Proof )
_______________________________ ↓
_______________________________ (2). 20 = 2×10 ( Proof )
_______________________________ ↓
_______________________________ (3). 20 = 20 ( Proof )
it answered why 2×10 = 20
Correct C. 20×10 = 200 Still Wrong answer
_______________________________ (1). 20×10 ≠ 20 ( Proof )

Answer:
Step-by-step explanation:
In a simple random sample, every member of the population has an equal chance of being selected.
Your sampling frame should include the whole population. To conduct this type of sampling, you can use tools like random number generators or other techniques that are based entirely on chance.
Biased sample
A sample is biased if individuals or groups from the population are not represented in the sample.
In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability than others.
Affects
It affects the internal validity of an analysis by leading to inaccurate estimation of relationships between variables. It also can affect the external validity of an analysis because the results from a biased sample may not generalize to the population.
