1. Rename the mixed numbers with common denominators
2. Add the mixed numbers together to get 15 4/6
3. Subtract the sum from 26 to get 10 1/2
4. Since the only term left on the left is k so k=10 1/2
Primcipal 739.30 Total = 778.90
Found by trial and error. I tried using equations but when you have TWO unknowns, it's (I think) impossible.
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

If nCk represents the number of ways k parts can be chosen from a pool of n, the probability of interest is the complement of the probability of selecting all good parts.
1 - (167C3)/(170C3) = 42,085/804,440 ≈ 0.0523
_____
nCk = n!/(k!(n-k)!)
