<p>you can basically do it as 5C1 * 10C2 on the calculator (using nCr). That is 5*2 which is 10.</p>
<p>ok, thanks gregunt. i was having trouble remembering it and thought that i may have missed it, which would have shifted all my answers.</p>
<p>which would have sucked so much.</p>
<p>if you omit 2, and maybe 1 wrong, u think its still possible to get a 730?</p>
<p>What’s the answer for the shirt one? I got either 9.5 or 19.5.</p>
<p>give us the context of the question?</p>
<p>Third shirt is $2 and first two shirts are original price. Can’t remember clearly.</p>
<p>if you omit 2, and maybe 1 wrong, u think its still possible to get a 730?</p>
<p>@skyhigh:</p>
<p>shirt question was experimental. I did not have it</p>
<p>Was rt3 the answer to something? I think it may have been a triangle one.</p>
<p>if you omit 2, and maybe 1 or 2 wrong, u think its still possible to get a 730?</p>
<p>Yes, it is possible. I got -4 and still got 730.</p>
<p>PLEASE TELL ME SQRT(3) WAS AN ANSWER…THIS IS KILLING ME.</p>
<p>sorry for the cap.</p>
<p>awsome thanks alot. u just made my day haha, thats what i need for a 1350</p>
<p>200sqrt(3) was the answer</p>
<p>No, not for that one.</p>
<p>It was another triangle one. It was in the earlier parts of a section. Not experimental.</p>
<p>200 sqrt(3) was indeed the answer for the triangular prism.
sqrt (3) was the answer for the triangles question.</p>
<p>Ok, thank God. Yes ^ that sounds exactly right.</p>
<p>I’ve been seeing some debate about whether a choice was (x+y)^2 or sqrt(x+y).</p>
<p>I could swear I saw that x+y is the square of z and they asked what z was. Did I read the question wrong?</p>
<p>for the question x, y, z are the three sides of the triangle, which cannot be the case? if i remembered correctly, i put x<z-y is not possible. did i get the choice right?</p>
<p>That’s correct. Since all three sides are positive you can write x+y<z, which is clearly impossible by the triangle inequality.</p>
