there is only one number less than 2, and six possible throws. So, P(n<2) = 1/6 Similarly, P(n>=3) = P(n∊{3,4,5,6}) = 4/6 = 2/3 P(n≠4) = 1-P(n=4) = 1 - 1/6 = 5/6

I think you're right, Cassidy. It looks to me as though this document is Federalist and political. In this excerpt, Jackson denied the right of a state to annul a federal law. He states that it is destructive of the Union.

Thursday, March 20, 2014 at 12:58pm

Math - PreCalc (12th Grade)
So it is D?
Thursday, March 20, 2014 at 12:51pm

Math - PreCalc (12th Grade)
You are correct; you cannot divide by zero. So, f(x) is not defined for x=4. However, for any other value of x, f(x) = (x-4)(x+4)/(x-4) = (x+4) So, if you define f(4) = 8, then f(x) = x+4 for all values of x, and is now continuous.
Thursday, March 20, 2014 at 12:43pm

Math - PreCalc (12th Grade)
I chose C. Is that correct?
Thursday, March 20, 2014 at 12:39pm

A B+ is well above average, so it's a good grade. We can't know whether it will affect your report card because we don't know your other grades -- both in this class and in others.

Wednesday, March 19, 2014 at 12:05pm

Math - PreCalc (12th Grade)
at x=5, f(x) = 0/0, or undefined. At any other value, though, f(x) = (x-5)(x+5)/(x-5) = x+5 So, f(x) is undefined only at x=5. By defining f(5) = 10, the discontinuity is removed. f(x) = x+5 for all x.
