Some math questions on dec sat

<p>I had the test with the Creole/math professor critical reading.</p>

<p>The math question regarding a box and tape was confusing. By stating that there was an additional length of three to each side really made no sense. Added with the picture that showed flat black lines, I was confused as to which side the tape was being extended to. </p>

<p>Did anyone else have this problem?</p>

<p>I think I made a stupid mistake for one of the graph questions where it gave like a scatterplot graph and then Points A and B were part of the not shown trendline. When I drew a line through A and B I found that it was at 9.5 but then when I found the slope of the line based on points A and B going from point A I got 9.0? Probably overworked the problem.</p>

<p>Was this part if the experimental section? My math section included the t + r question, the temperature question</p>

<p>what was the experimental math section? I’m dying to know.</p>

<p>How is it 8?
If you draw a table…
Person 1 Person 2
1 4
2 3
3 2
4 1</p>

<p>(4 ways)
(then again, I probably did something stupid)</p>

<p>Also, what’d you guys get for the tutors that went two days, and the mass of the animal (S(m)=10m^(2/3))?
I got 4 and 27 respectively.</p>

<p>What did you guys get for the circle with equip arcs question? I said couldn’t be determined because the lengths of the arcs could be anything depending on the distance of the points. </p>

<p>And what about the value of k that gives no x?</p>

<p>@tbradsworth that’s what I got for both</p>

<p>Was the last grid in 2.4?</p>

<p>K value for no x = 2/5</p>

<p>For the arc question, is the one you are referring to the one where you had to find the perimeter and it had a radius of 6 or 9?</p>

<p>How many ways to divide 5 identical coins between two people so that each person gets at least one coin?</p>

<p>1-4
2-3
3-2
4-1</p>

<p>4 ways</p>

<p>Was the area of the sliver of the circle 1/10? It had 36 degrees…</p>

<p>For the coin question, I put 4 also but i saw somewhere someone said it was 10 bc:
1-1, 1-2, 1-3, 1-4, 2-1, 2-2, 2-3, 3-1, 3-2, 4-1 because it said “at least 1 each” I sure hope that guy is wrong</p>

<p>^^Me too. I think it was 4.</p>

<p>@Physics got my fingers crossed on that one hopefully it was experimental. Either way I have at least -3 because i missed 2 grid in, omitted one in the first 20q math and one in the other, NOT including this coin one. I’m assuming one of the middle maths was experimental?</p>

<p>No. It said radius 6 find length of arc</p>

<p>@mvp1993The coin was not experimental but I wish the best of luck to you. </p>

<p>Did anyone get 1/10 for the fraction of the area of that circle?</p>

<p>Did anyone get 3/5 for the slope of a line?</p>

<p>Slope of what line and what fraction? I don’t remember those questions.</p>

<p>@Oscarlany: what was the last problem? I use fractions for everything and I don’t remember.</p>

<p>@IGotAn i got 450 cuz 300 birds for 40% so when you add 300 birds more than it will take 80% now u left with 20% which is the half of 40% so 150 birds</p>

<p>Therefore, 300 + 300 + 150 = 450</p>

<p>There was one question about a quadrilateral on a graph. It asked for the y-coordinate of one vertex. I remember there was a point (0,4) and (2,w). The question asked for w. This was #8 on a math section (the last one before grid-in questions started). I remember putting “A)” 5 and 3/5. Was that correct?</p>
