October 6 SAT math

<p>thats experimental, i think. i dont remember that.</p>

<p>y= -x is definately (-3,-3) reflection of just x would be (3,-3)
reflection of -x means it goes to the negative x side.</p>

<p>For that question with the different variables (z,w,x,y or whatever), what were the answer choices? I know the answer was 2. Was 4 a choice? I remember just adding the equations and all cancelled out but for some reason I remember getting 4. Either I remember wrong and really put 2 or I made a careless mistake :P</p>

<p>yeah four was a choice. thats what i put, because i accidentally ran out of time.</p>

<p>yo mathizlyfe...i had the same exact idea as you..soo i got it wrong...but it said reflected...not on the line y=-x</p>

<p>anyone know what -3 wrong on math is....spartyon?</p>

<p>3 wrong is prob 740 ish</p>

<p>3 wrong on math is more like 720.</p>

<p>turksouttacyprus, it did say the line y=-x</p>

<p>i got 3 wrong on math in march and got a 720</p>

<p>does anyone remember the f(x) graph? i don't remember how many zeros i said was right, seven maybe? i'm starting to see this graph in my dreams...tell me please!</p>

<p>I got 3 math wrong in June and I got a 740 ;)</p>

<p>thats cuz u missed some on free response, if its all on MC then u get 720-730</p>

<p>I may be crazy, but this is how i remeber the campers questoin</p>

<p>" At a camp of 240 kids, 5/6 know how to swim. If 1/3 of campers know how to climb (or it says "took the climbing class") then what is the minimum amount of students taking a climbing class that know how to swim"</p>

<p>Everyone says 40, but to me that question is saying that 1/3 are not in the class so its 5/6 and then 2/3. I did 5/6 of the 240 (200) then i subtraced 1/3 (of 240) from them becuase 2/3 of campers are in the class. This left me with 120. Now that i type it up i seem wrong, but i swear that has to be the answer. lol. ****.</p>

<p>for the temperature question were the answer choices equations with the letter t?</p>

<p>It was the first choice.</p>

<p>thebaron, how the hell could the answer be 120 when there are only 80 kids in the climbing class?</p>

<p>lol.</p>

<p>I don't remember what I wrote down, but taking a second look at the question I get this:</p>

<p>If there are 240 total, and 5/6 of 240 is 200. 1/3 of 240 took the climbing class, which means 80 took the climbing class. The absolute least amount that know who to swim is 40, because you assume that EVERY kid that DOESN'T know how to swim is taking the climbing class. And only 40 total, don't know how to swim. If the total number of 'climbers' is 80, and 40 DON'T know how to swim, then the smallest number that know how to swim is 40.</p>

<p>GOD, i hope I saw that when i took the test. I have a feeling I didn't though.</p>

<p>^^same logic.
If every camper is either a swimmer, or a climber, or both, then
160 - swimmers only
40 - both
40 - climbers only.</p>

<p>If one out of 240 opts out and refuses to do either swimming or climbing, there'll be
159 - swimmers only
41 - both
39 - climbers only,
1 - refusenik.</p>

<p>If two campers can't do a thing, the distribution will be
158 / 42 / 38 / 2.
.......
If 40 campers are complete slackers:
120 / 80 / 0 / 40.</p>

<p>The number of ambi-sportous ranges from 40 to 80, so the least number is 40.</p>

<p>Turksouttacyprus....now i remember I had actually put (-3,-3)!!!!! I answered right....
I recall I was on teh verge of answering 3,-3 but then in the nick of time I realised that there were 2 options (3,-3 and -3,3) which would fit into that logic....So i smelled some catch and ended up answering (-3,-3)..Thank the heavens!!!!
hard luck for you tho'</p>
