Answer: "13,000 books" represents the population.

"200" books represents the sample.

Step-by-step explanation:

  • A population is the term that denotes a whole large possible group of individuals, objects, events or measurements.
  • A subset of population is known as ample.
  • When population is too large to the researcher  , then it uses sample to represent the entire population.

Here,  "13,000 books" represents the population.

"200" books represents the sample which is a subset of 13,000 books.

shayla is financing a house for $126,750. She has to pay $450 plus 1.15% for a brokerage fee. How much are the mortgage brokerag
ANEK [815]
Answer: $1,907.63

Explanation:

It is stated in the problem that the brokerage fee is $450 plus 1.15% (meaning 1.15% of $126,750). Hence the brokerage fee is computed as follows
  
(Brokerage fee) = $450 + (1.15% of $126,750)
                          = $450 + (0.0115)($126,750) 
                          = $450 + $1,457.625
                          = $1,907.625

Since there is no half cents today, we round-off the brokerage fee to the nearest cent. Hence the brokerage fee is $1,907.63.

Note: In the computation of brokerage fee, we need to change 1.15% to  decimal.
