<p>I think that one was manipulating language, because that’s all she talked about there…</p>
<p>This one was probably supposed to be easy maybe I read it wrong or perhaps im just dumb…</p>
<p>n+n=nk k+k=nk what is n+k</p>
<p>i put manipulating language at first, but if you look at it in the context of just the lines mentioned, it is elaborating on the previous statement about genetics ppl and botanist controlling plants. Selfish reasons isn’t really mentioned in the text.</p>
<p>I put 2 for both n and k because it never said they had to be distinct.So answer is 4?</p>
<p>This was easier than any practice test I have taken. I think the math curve will be harsh.</p>
<p>choyfin: 19 also works (that’s what I put :D)</p>
<p>@eric2dea, I wasn’t sure either but I put 4?</p>
<p>@eric2dea ahh i was staring at that question for the longest time. i feel like there was some trick to it. i got 4…</p>
<p>@levinel can you explain the subsets one–i’ve never even heard of subsets before lol</p>
<p>That’s what confused me as well…but how can n and k logically be the same number? It was not a typographical error I hope…</p>
<p>OMG I had the same questions for you all! Is it 4!!! I hope…but then there would be other exceptable answers as well. </p>
<p>This question:
n and k are both positive numbers
n + n = nk
K + k = nk
what is n+k?</p>
<p>n + n = nk
2n = nk
n = k</p>
<p>Because n = k,</p>
<p>n + n = n*n
2n = n^2</p>
<p>So n = 2, which means k = 2, which means n + k = 4, right?</p>
<p>Surely… .
I believe set A consisted of all numbers that were multiplies of 4.
Set B consisted of all factors of 100.</p>
<p>The question asked which subset (set of numbers that pertain to the sets A and B) is in B but not in A.
It was E (4,25,50,100) because they are all factors of 100 but not all are multiples of 4 (i.e. 25 and 50).</p>
<p>Hope that helps!</p>
<p>yeah it’s 4</p>
<p>n + n = kn, k is 2 (like x+x=2x)
k + k = nk, same thing</p>
<p>2+2=4</p>
<p>so did other ppl put controlling nature for the bees one?</p>
<p>Agh, I was so caught up by the subsets one I just started plugging numbers into my calculator for the month question and blindly accepted 20% as an answer without really thinking about it so I could go back to the subsets, maybe I had a typo 
The subsets one made no sense to me at all. AT ALL. I put the 4, 25, 50, 100 though. But I also put 19 for the one fill in, and 4 for the n’s and k’s.</p>
<p>@levinel thanks, can’t believe i got such an easy problem wrong lol…</p>
<p>by the way, what are the chances of getting 1 wrong and still getting an 800?</p>
<p>What was the answer to the question about stamps. I ran out of time and guessed C.</p>
<p>@fidelgato i also put controlling nature</p>
<p>do you guys remember the problem about how each student has either [2 pens and 1 pencil] or [1 pen and 2 pencils]</p>
<p>If the average number of pens per child in the class is 1.4, whats the average number of pencils per child? </p>
<p>I just guessed and picked A- 1.4 </p>
<p>:( can someone explain it?</p>
<p>what was the answer to the question that asked which expression has the highest maximum value? there were Xs and parentheses and ^2s in it</p>
<p>Both the averages have to add up to 3. So 3-1.4=1.6 Simple as that.</p>
<p>And i said choice A for the highest maximum value question but it was basically a guess.</p>
