November 2008 SAT Math

<p>What was the answer with the one
inclusive
100-110</p>

<p>the answer had to be all the even integers so
6??</p>

<p>No, the answer to Johan and Maria selling concert tickets was not 7/16. This was a trick question because you did Johan's tickets sold divided by Maria's tickets sold. The question asked for Johan's tickets sold over the TOTAL of Johan and Maria. So, you took the sum of the white bars for Johan's tickets divided by the sum of the white bars and shaded bars to get the total of Johan and Maria. The answer was 7 / 23. I did 7 / 16 first but realized the trick.</p>

<p>9 + 7 is 16
so 7/16
duhh</p>

<p>now im really confused. </p>

<p>how would you get 23 opposed to 16? I cant remember what number I put, I only remember the 7. </p>

<p>but my thought process was adding up johan's bars and that number (7) over adding the bars of them combined. would that have gotten me 16 or 23???</p>

<p>Yeah... it was definitely 7/16.
And definitely 6 for the 100-110 problem.</p>

<p>I think the person who got 7/23 probably counted Johan's tickets and got 7, then counted them both for 16, but instead of stopping there, s/he forgot the 7 was included in the 16 and added another 7 to get 23... which isn't right, obviously.</p>

<p>I thought i put that, but how are people possibly getting 23?? its making me think i made a mistake. i thought it was straightfoward...</p>

<p>I definitely didnt do that. lol thats one silly mistake i missed.</p>

<p>OK, I also got 7 / 23 and I'll try to show you why. The way you find what they're asking you to look for is by taking Johan's total number of tickets divided by the sum of Johan's tickets sold and Maria's tickets sold. We all know that Johan's tickets sold came out to be 7 (the agreed-upon numerator). But, they are asking you to find the fraction of his tickets and the TOTAL tickets sold by both of them. So, you have to add his 7 tickets sold to Maria's total of 16 tickets sold to get 23 tickets sold in total. The fraction of his tickets sold and the total tickets sold by both of them is 7 / 23. It was a trick question because people interpret it to mean that you have to find his tickets divided by her tickets.</p>

<p>there was no trick
it said find his fraction of the tickets that he sold
his fraction means his part</p>

<p>since there was a total of 16 tickets sold and he sold 7
his fraction sold would be 7/16</p>

<p>16 was the number of total tickets sold, actually. Maria sold 9 and Johan sold 7, so it's still 7/16.</p>

<p>The graph was arranged into Concert 1 and Concert 2, and I'm sure both concerts had less than 10 tickets total sold, because the graph only went up to 10, so this eliminates all possibility of 23 being an answer, because 10+10 would equal 20 max.</p>

<p>I'm very sure it's 7/16.</p>

<p>the sum of Johan's and Maria's section of one bar IS the total of tickets sold. therefore, maria sold the length of that bar - john's section of tickets. </p>

<p>so you just add up the lengths of both bars...16. you didn't need to know how many tickets she sold herself at all.</p>

<p>look at it like this</p>

<p>u sell 7 apples
and ur friend sells 6 apples</p>

<p>what fraction of the total apples did u sell?
7/(7+6) = 7/13</p>

<p>he interpreted the graph like (just making up numbers)</p>

<p>Johan's section, the first one, went up to 5, so he sold up tickets. Maria's section ended at 7, so he thought that she sold 7. but she sold only 2, because her bar + Johan = the total they sold.</p>

<p>the legend did prevent you from making that mistake. althought the wordings of a lot of these questions were tricky, this really wasnt one of them...</p>

<p>y are we wasting time on this question
everybody i know got 7/16</p>

<p>Collegebound, I think you're exactly right. That must be what s/he did when interpreting the graph, and I can almost see how one might make that kind of mistake, but again, the graph's legend pretty clearly indicated how to read the bars...</p>

<p>I didn't take the test, but vowel problem is definitely 8. </p>

<hr>

<p>Let's assume you start with a vowel- You have two options for blank 1, two options for blank 2 (a consonant). The second two blanks there is only one vowel and consonant left, so...
2x1x2x1 = 4. </p>

<p>BUT REMEMBER! That's assuming you started with a vowel. Since you can start with a consonant, multiply the number of items by x2. = 8. </p>

<p>Answer to h(x) = -x + 3, find h(-x) is OBVIOUSLY x+3. </p>

<p>Come on guys, K.I.S.S. You just need to plug in -x into -x+3. -(-x) + 3... = x + 3.
You guys overanalyze this way too much and end up getting stuff wrong. The SAT isn't some kind of freaky test Satan wrote where every question has some strange nuance or trap that you need to figure out.</p>

<p>Im 100% sure it was 7/23.</p>

<p>I spent over 5 minutes on that question.</p>

<p>btw I have two 800's in math under my belt.</p>

<p>I'm 100% sure it's 7/16.</p>

<p>Oh, what now?</p>

<p>^
lol i hope that was sarcasm.</p>

<p>hopefully the 5 minutes spent on the problem implied sarcasm...</p>
