<p>1) “which set shows an inverse function” question with the x and y table
2) a pyramid with sides 8, find the area of the base (answer choices were 32 radical 2, 64 radical 4, 64 radical 2, etc.)
3) an integer with certain digits; how many different ways to make a new integer without repeating digits</p>

<p>were these experimental?
I hope so :/</p>

422

<p>two might be</p>

423

<p>for 2 u sure it wsa 8 cuz i had experiemental but mine said sides of 1
and also
1 and 3 are not experiemental</p>

424

<p>what was the answer to 1?</p>

425

<p>b its the one with the fraction in the first row and column</p>

<p>Thanks AKittka, lol!</p>

428

<p>its weird…i had extra math section
but i don remember ever seeing pyramid question</p>

429

<p>Was the inverse relationship question the chart where x and y always multiplied to the same constant, so as one increased the other decreased (and vice versa)? In this case I believe the constant was 24. I’m 95% sure but just want to double-check,</p>

430

<p>hey if i missed 3 on math (so -4 overall with the .25 thing) what would that equate to about?</p>

431

<p>730!!! i guess so.</p>

432

<p>I got a -5 raw score (-3 questions, 1 omit) on the November 2007 test and got 720, to help with the curve idea</p>

433

<p>what wud about 7-8 omit and 2 wrong be ?</p>

434

<p>650-670 —</p>

435

<p>for “Triangle w/ variables U & T: (U*T)” what was the problem?</p>

<p>also does anyone know the specific numbers that were in the the correct table of the inverse function question?</p>

436

<p>^ 2 and 12, 4, and 6, a few others that I don’t remember…probably 8 and 3.</p>

437

<p>Geoffrey, i think for that inverse proportion one, xy=12, because i remember seeing 3 and 4 in the first row. Anyone remember anything about that question?</p>

438

<p>ya ii think it was either b or c dont remember wat i put but xy was always 12</p>

439

<p>any predictions for 2 omit and 2 wrong…pleeeaaasse</p>

440

<p>wait what was the hypotenuse 6sqrt5 problem again??</p>
