Use long division for dividing
Here 'v' term is missing so we use 0vW
Divide 
by v-10 using long division
Step 1: Put 8v^2 at the top
step 2: multiply 8v^2 with v-10 and put it at the bottom
step 3: subtract it
We will get remainder 6
so quotient is 
Remainder is 6
We know that there is a total of 900 cells, and 37 of the samples 60 are red. 900/60 is our unit rate of 15. 37 times 15 is 555. We will see 555 red blood cells in all of the cells.
555 is our answer.
Please forgive any typeos because I did this on my phone.
Answer:
(B) A selected group of participants that is representative of a larger population
Step-by-step explanation:
A sample statistic is a piece of information that you get from a fraction of the population. This information is representative of a larger population.
For example, someone wants to conduct a survey about the most popular NFL team in Syracuse, NY, if it is the Buffalo Bills or the New York Giants. This person is not going to ask each person for whom they cheer. They are going to collect data from a fraction of the population and this data will be expanded to include the entire population.
So, the correct answer is:
(B) A selected group of participants that is representative of a larger population
