<p>THERE ARE LOTS OF REPEATS. 56 QUESTIONS IN TOTAL. 2 ARE NOT SUPPOSED TO BE HERE. HELP!</p>

<p>I thought it was 3/2 for the first one, not 2/3.
4x=6 or something</p>

<p>are you 100% sure?</p>

<p>theres a 3:2 one. the running one.</p>

<p>Pretty confident, unless it’s 2/3 like everyone’s been saying. I haven’t seen how they got that so i think I’m right</p>

<p>o shiii, i was looking at a different grid in question about the 6 thing. sorry bout the mess up, idk what the first 6 is.</p>

<p>what is the 32 answer for…what question?</p>

<p>can anyone explain why the heck the gas mileage one was 26 miles? I got 26.52 median, so I rounded up to 26.75. I dunno how 26 was right.</p>

<p>also, what was the answer 100 for?</p>

<p>btw IT WAS 3/2. There was something in that question that gave it away, i remember</p>

<p>and what was 77?</p>

<p>what do you all think the curve for math will be? in a range of…</p>

<p>alright updated the 2/3 to a 3/2 and got rid of the [?] Answer 6.</p>

<p>there is still some repeats. im thinking one or two of the five answers…</p>

<p>Oh. 3/4 (.75) was the shifted parabola</p>

<p>can u go over it for me. i wanna see if i got it right.</p>

<p>^
can anyone explain why the heck the gas mileage one was 26 miles? I got 26.52 median, so I rounded up to 26.75. I dunno how 26 was right. </p>

<p>plz i really don’t get it</p>

<p>I think it was y=a(x-2)^2 through 2 points</p>

<p>i added up the total number of cars…figured out what the median number would be (what term)…then figured out that the median number is in between 2 26’s…so median = 26</p>

<p>It was really simple.
Medians are not means.</p>

<p>You count from the left and right in an alternating fashion. Didn’t the graph look from left to right
After you eliminate whole bars (left right left right) you’ll find that there are 10 remaining data points for 26.</p>

<p>therefore the median must be 26. There was really no math involved the way I did it.</p>

<p>or do it viggy’s way lol</p>
