Answer:
7/10
Step-by-step explanation:
To find the probability that a student is a liberal arts or female, we have to add together all of the people who were female or liberal arts majors in the study. If we add those together, (15 + 18 + 17 + 20) we get 70. 70/100 can be simplified to 7/10.
The answer is a. b>-2 because
6b<24
b< 24/6
b<4
And
4b+12>4
4b>4-12
4b>-8
b>-8/4
b>-2
First let's rewrite it...
18a^2 + 20a + 8
Factor out a 2
2 (9a^2 + 10a + 4)
I think B not 100%shure ,you could prob go ask this on yahoo and get a bit more help ;) sorry I couldent help more
