(a) -1
(b) -2/3
(c) 2/3
(d) 1
(e) 3/2

If the mean equals the median, then for three numbers 
a, j, k,
j = the mean and the median

anonymous · Answer

yeah i got that so far and k is 3j

anonymous · Answer

so a = 1/3 j

anonymous · Answer

Not right huh

anonymous · Answer

yeah i think then the answer would've been 1/3 but that's not an answer choice right?

anonymous · Answer

I think I'm right, not positive, but pretty sure.

anonymous · Answer

so which answer choice is it?

anonymous · Answer

You can rule out the negative numbers   :)

anonymous · Answer

I think if you plug the other answers into the definition of mean, they will not be correct.  The problem has a problem.

anonymous · Answer

i tried plugging in numbers (a=-3, j=3, and k=9) and then it worked out to be -1 but idk if that's right.
