2011 January SAT: Math

<p>same skiiz</p>

<p>I thought choice E was ((sqrt5)-1)/2. That’s what I got…</p>

<p>I felt really good right after but now I think I bombed it… :(</p>

<p>really? the segment was drawn to scale and it seemed greater than 1/2 idk</p>

<p>So, about what score would be getting all MC right and missing one free response problem?</p>

<p>770-800? </p>

<p>Also, was the question with the working/not working radios asking for the probability of picking 2 radios that both did not work, or of 1 radio being picked that didn’t work if the other one that didn’t work was already picked?</p>

<p>why the overlapping one is 2???</p>

<p>To anyone who is wondering if he or she had a math experimental, I know for a fact which of my math sections was experimental.
If you had a question something like this in a section, then it was def. experimental:</p>

<p>Two letter a’s and one letter b are displayed in three possible arrangements below. How many possible arrangements would there be for two letter a’s and two letter b’s?</p>

<p>the original length was 30, with overlapping it was 22, which means there was a difference of 8, and the sticks overlapped in four places, 8/4 = 2</p>

<p>vicky:</p>

<p>(5*6)-22=8, 4 overlapping sections. 8/4=2</p>

<p>Skiiz, it seems like it was 1 radio being picked, thus 3/5…according to a few people earlier in this thread. Unfortunately I thought it was the probability of picking 2, so I did 4/6 x 3/5 I think. Should have read more carefully…</p>

I definitely had the math experimental section, but I did not have that question in any section.</p>

<p>so for that 1/(n)(n+1), was it 50/51 or 51/50. I got 50/51</p>

<p>I had a question with 2 inequalities and asked which value worked and I plugged all the answers in and both A and B worked… I think one of the inequalities was x^2+8x<=15. Anybody have this?</p>

<p>Onyx, it’s 50/51</p>

<p>had that, but i think my answer was b</p>

<p>@drillkid
yeah I had that question, do you think you had a math experimental section?</p>

<p>I had a question with 2 inequalities and asked which value worked and I plugged all the answers in and both A and B worked… I think one of the inequalities was like x^2 +8x <= 15. Anybody have this?</p>

<p>I remember this question… -4 right?</p>

<p>@yvettec
I did the exact same thing…</p>

<p>I dunno. I had 3 math sections. I don’t remember if I put A or B. Did anybody have both answers A and B work or was I just being stupid? I like checked like 4 times and even typed the whole things into my 89 just to check…</p>

<p>does anyone remember that male to female ratio in a company? it was 200 male, and 250 female workers total i think.</p>

<p>Yes, i got 200 males to 250 females.</p>
