Do you remember the sphere question one with 2 circles , how many common points did you think of ??

Yeah tht was a toughie. I selected 'cuts at no places' nd cuts at two places
cux it was said tht circles r drawn on surface of spehere not inside the sphere...so sm part of circles might be outside the sphere...thus no common points

And the cube from A to B point how many different 15 unit paths were there ??

5

What was the essay prompt?

Something about is being certain better than having wisdom. The problem is that this topic can be interpreted in different ways.

I think the circles can intersect at 0,1, or 2 places.

1 is possible if they only touch.

I got the question about 27 students sharing 17 lockers wrong, I put 10 but it should be 20 since 2*10
