" of " means multiply
2/3(27) = 54/3 = 18
2/5(20) = 40/5 = 8
so 2/5 of 20 is smaller
As a fraction it would be 13/52
As a percent it would be 25%
Answer: Population
In statistics, a population is the entire group of people you want to determine some fact about (eg: average height). A sample is a subset of the population that should ideally represent the population.
For a linear equation like this there will always be infinitely many solutions if you let x and y be any real number. So you can just pick any x and find the corresponding y. Take for exmaple x=1 then we get
-1+2y=8
2y=9
y=9/2=4.5 so an ordered pair that satifies your equation is (x,y)=(1,9/2).
Now you can go on and find more.
1. Calculate the market share that you have (7%)
2. Calculate what 10% of the market share would be
3. Subtract 10% from 7%
