There are 48 available subjects. Researchers should select 4 of them for their experiment.
We should find the number of possible different random samples. The order of the selected subjects is not important. This means that we need to find how many different combinations of subjects from total 48 are possible. <span>A </span>formula<span> for the number of possible </span>combinations<span> of </span>r<span> objects from a </span>set<span> of </span>n<span> objects is: n!/r!(n-r)!. In our case n=48 and r=4:
C=48!/44!*4!=48*47*46*45*44!/44!*4!=</span><span>48*47*46*45/4*3*2*1=4669920/24=
194580.</span>
<span>First
year sale = 150 000 dollars,
Then it grew 8% for the second years, and 2% each year for the next 2 years.
Total growth from 2-4 years increase is 45 000 dollars
Find the growth for the year 2
=> 8% = 8/100 = 0.08
=> 150 000 x .08
=> 120 000
Thus the growth of the ABC company for the second year is 120 000, that makes
it
=> 150 000 + 120 000
=> 162 000 dollars.
