shikorz413 · May 3, 2010, 11:26am

can someone please explain what the runner question?
what was the question exactly and why was it 3/2?

shahdin · May 3, 2010, 3:34pm

I think it was 3x+ 5= Y

not 3X -5 = y cuz then y would be -5.

gthopeful93 · May 3, 2010, 7:39pm

Do yall remember the question that yielded 60 as the answer?

pbp217 · May 3, 2010, 8:19pm

ok so there was a question in one of my math sections it wasnt an experimental because i had four reading sections it was like what is the median of odd positive integers to 101 and the options for the answer were like 99 99.5 98 100 101 and i swear i didnt read it wrong i read it like 2000 times and like no one else that ive talked to remembers it…does anyone remember it

Linger · May 3, 2010, 8:37pm

pbp who cares because its experimental

DoctorTye · May 3, 2010, 8:43pm

hey DOCTORTYE, you might also wanna change this one:

It could be very misleading to some people who put something like 5,7,8,10,11,13, 14, or 16, which are all possible and correct answers.

I realize that there are too many questions. As people remember the final questions, the list will become more accurate. @fresh101: I do recall an integer parameter for x, but i might be wrong. Does anyone else remember?

found 3=k; r, s, and t were listed

Can anyone give more info on the water graph?
Was the answer the obvious increase; I’m worried that I might have bubbled in 1:00-1:04. Is there any reason why I might have done that?

[.5 and 2 are on a number line. what does 1/4th of the way from .5 to 2 equal]
ANSWER: 7/8

I dont really remember what i put for this one, but i think i put 7/8 as well. However, after re-reading the question (or at least what we remember the question to be), is it possible for the CB to have meant for the answer to be .375? I’m just worried bout my 800 and because its slightly unclear or else they would’ve specified, the ‘point’ that is 1/4th the distance between 1/2 and 2? Or am i just worrying for nothing.
