| wheel, a raw score of 43/50 is always an 800. That's 6 wrong, or 5 wrong and 1 omit, or 7 omits, or 3 wrong and 3 omits... |

| I think so. If the standard deviation is zero, then everyone's individual score in the class should have zero difference with the mean score of their scores. If the scores were all same, then, the mean would be the same as the score.
I'm not sure about the second questions of kapwatt. I think I omitted that questions because I was running out of time. or skipping. | |

| Isn't 1:00 the time that we can start discussing?
Well, either way -- I'm not asking for an answer, but... what was the question on the 3D plane (x,y,z) asking for? I went into this nervous freakout mode when I took this, and I don't think I actually read the question... | |

| I have no idea what happened to my calculator during this one problem - I kept graphing it over and over, I tried changing everything to get some sense out of it, switch radians-degrees, check to make sure no extra functions typed in...But nothing made sense...I just graphed it and it is fine...I hate when this happens. | |

| I thought it was pretty easy. Much easier than my practice books at least.
I left 5 blank, and might have missed around 5-8 elsewhere from stupid mistakes.
Overall, not bad at all. | |

| Oh yay! I got that for the midpoint/3D one too.
Does anyone remember the percentage/proportion one? It was like p(t)=something, and how much time would it take for 75% of the issues to be resolved? | |

| just plug in the numbers for T for that one, until you get .75. I believe the answer was D.
