<p>OHHH yes i remember now.
And yes i’m 100% sure it’s .7
Can someone compile a list of known answers… :(</p>
<p>what did u guys get for the standard deviation question with the average grade and sample grade?</p>
<p>you could’ve just plugged and chugged for the ln one… if forgot what the question was though</p>
<p>I think I may get 770-790, should I cancel it?
I’m retaking it on June, and…</p>
<p>It was A for the standard deviation one. You had to calculate the z-score for each one.</p>
<p>for the hyperbola one did anyone use the cordinates given in the lines themselvs?</p>
<p>**** i put (0,0) …</p>
<p>I did.
I got -5,0 or something like that.</p>
<p>@studious, a was the one that was like 84 75 s = 3 right? something like that?</p>
<p>i had forgotten how to calculate z score…ugh</p>
<p>^I put -5,0 as well.</p>
<p>What did you guys get for that one that was f(x,-y) = ? I put that it equaled the same thing as the f(x,y)</p>
<p>@BART2385 same</p>
<p>cuz -y squared is same thing as y squared</p>
<p>hmmmmmm i dont remember -5,0…</p>
<p>^yup thats what i got</p>
<p>i didn’t put -5,0 cause i thought it was like a tangent line or something like that to the parabola</p>
<p>I got that f(x, -y)=f(x,y).</p>
<p>(-5,0) as well (it was where the lines intersected)</p>
<p>what did people get for the circle tangent to the x and y axis?</p>
<p>Yeah, the z-score was 3. (84-75)/3 = 3. And that was the highest. </p>
<p>The hyperbola center was (-5,0). </p>
<p>This is great! I haven’t gotten one wrong yet. Did anyone get the X and Y migration one? I just skipped it because I thought it would take too much time.</p>
<p>@infamous, 3.14
anyone? standard deviation? what were the values?</p>
<p>EDIT: nevermind, thanks.</p>
<p>For all of you arguing over the range question, 6.5 didn’t work because the question stated that “t” had to be an integer.</p>
<p>does anyone remember any other questions that hasn’t been mentioned in this thread yet? i wanna see if i got them right</p>
<p>@swoony, no im not talking about the one that was like (x^2/16)+(y^2/25). This is the one that asked like “A circle touches both the x and y axes at one point. What is the center of the circle?”</p>
