12/12 would be the fraction of all students...now subtract all of the fractions that represent students not in the volunteer programs...
12/12-2/12-4/12-1/12
(12-2-4-1)/12
5/12
So 5/12 of the student participate in volunteer programs.
Just multiply 20 x 30 and you get 600 and that is your answer :3<span />
50 percent is the probability
You first need to make sure the denominators are equal, then when they are, you can add/subtract the numerators. Then you can place the result over the common denominator.
I hope this helps! :)
Answer:First three terms: 11,20,29 .
Step-by-step explanation:
Write a systems of equations. tn=a+(n−1)d. sn=n2 (2a+(n−1)d). So,. 110=11+(n−1)d 726=n2(22+(n−1)d).
I hope this is right
