y=mx+b Question: What is b? 1) m=3b - insufficient 2) x intercept =-1/3 - y intercept could be positive or negative depending on the slope of the line. Insufficient. Together: we have a point x intercept (-1/3,0), plug it into the y=mx+b equation: 0=m(-1/3)+b Using stmt 1--> 0=3b(-1/3)+b - we can so...

ok, what's the question?

IMO answer is B.

If we were to know that the same tranquilizer that's used on the rhinos also has the same effects (inhibits fertility) when used on other large mammals, then our conclusion that there is something in the tranquilizer that inhibits fertility would be true.

I think D is a trap. In the argument, we are told that the amount of insecticide needed per acre to control insect pests was only slightly lower so it doesn't matter how many acreage of cotton each type has, what matters is the comparative cost of the insecticide.

Re: sets

The best way is to draw two sets that intersect (see my attachment). It's easy to visualize that what you are looking for is the area outside of the intersection which is given by 30/400+30/400=3/20 400 people join the local gym. 60 people take aerobics, 60 people take yoga. Of these, 30 people take...

IMO, the answer is E.

When I saw that it was an inference question, I approached it the same way I do in RC questions. in RC, you have to demonstrate that the information you are inferring is found somewhere in the passage. I think you are thinking of the weaken/strengthen type ...
