<p>Does anyone remember the question that was something along the lines of </p>
<p>X^2 - bX + 25 = 0?</p>
<p>Where x=5 or something like that. </p>
<p>Was the answer -12 or 12? I put -12 and I’m gonna be annoyed if I made a sign error since that would mean 2 wrong in math :(</p>
<p>Also, I had 4 math but only 1 grid-in, so does anyone know which math was experimental?</p>
<p>what did u guys get for math question that mentioned about p^2, r^2 thing? the possibility problem. did u guys got 4?</p>
<p>its 90 because 360 are adults so 180 are children and half of the children are >2 so 90.</p>
<p>@woodjew
I got 90. 2/3s were adults, and 1/2 of the remaining were older than 2, no?
So, 540<em>(1/3)</em>(1/2) = 90?</p>
<p>Or… was it 1/3 adult?</p>
<p>I put “the lodge…” , too. But I don’t think that was 14. 14, was something like “inference” but idk if there’s another choice with just “inference” and nothing after it or if there’s just one because anything after inference is unnesscary</p>
<p>I got 90. I think the question stated that 2/3 of the 540 were adults. Then half of the remaining were older than 2. Find the children under 2.</p>
<p>@Masculist Man x^2 + bX + 35 = 0 and they asked what value of b gave x = -5</p>
<p>Answer was 12</p>
<p>@Vanilla Yeah I know… I wish they would let us take the test booklets home… Thanks.</p>
<p>@Woodjew It was 90. I got 180 first but when I reread it I realized they said 2/3 of the 540 were ADULTS. So the remaining 180 were either over age 2 or 2 and younger. The next bit of into you got was that half 180 were over age 2. That means that only 90 were 2 and younger.</p>
<p>@vanillathunder they gave you that 5 was the radius of the smaller circle. therefore, 10 is the r of the larger one and you get 100pi/25pi = 4</p>
<p>@wood it was 90 I’m pretty sure. 2/3s were adults, and the remaining were kids. You were asked to find 2 and under. It said 90 were 2 and above. 180-90=90</p>
<p>Also answer was 14 for the 8th term…not 16</p>
<p>What was the experimental math section? I have no idea what my experimental was, I forgot to pay attention to how many sections of each subject I did…</p>
<p>The 0,2,4,…,n one was 14 (not 16)</p>
<p>Raging: the given was that 5 was the radius of the larger circle, I agree with you about it being given, but it was certainly the larger circle</p>
<p>@MasculistMan its -12 because (x-5)(x-7)</p>
<p>@ragingrag the radius of the smaller circle was most certainly 3.</p>

<p>I’m not sure if it’s AD that’s 5 or OD that’s 5 though.</p>
<p>Edit: Okay apparently links to images don’t work so…
I’m not sure if it’s the entire outer radius that’s 5 or if it’s 3+5.</p>
<p>@Masculist i got 12
(-5)^2 + b(-5) + 35= 0
-5b=-25-35
-5b=-60
b=12</p>
<p>Had two W. One of the paragraph improvements were about carrots, the other had the #29 proceed/preceded question (I personally put A/B, or whatever it was). Which one was experimental?</p>
<p>the one about the woman and her husband was experimental</p>
<p>Ok there are too many different answers to the ratio of the larger to smaller circles. I got 64/9</p>
