Given sets p , q , and s above, which of the following sets represents s ∩ ( p ∪ q ) (the intersection of s with the union of sets p and q )?

If a(0,0,0) and b(2,2,2) are points in coordinate space, how many paths are there from a to b that move from one lattice point to another in the positive x-,y- or z- direction?

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

8000 + 8800 + 8000 + 8 million + 80 trillion + another a katrillion equals
