d = [(s – 4) ⁄ (s² – 9s + 20)] • [(s – 5) ⁄ 4]    ...    rearrange terms 
d = (s – 4) • (s – 5)   ⁄   [4(s² – 9s + 20)]    ...    factor denominator

olga2289 [7]

Answer:

<h2> A. is a list of population elements from which the sample will be drawn</h2>

Step-by-step explanation:

Sampling frame is the list of people or items from which a sample is taken.  

Sampling is used because it is almost impossible to study entire population. Sampling allows us to find information about a population on the basis of results from a subset of the population, without studying every individual. It is easier and cost effective process.
