<p>SInce y=5, it is not true that (0 < y <4), so by the contrapositive, it is NOT true that (x < 3), so the answer is that x is > or = to 3.</p>
<p>Anyone remember getting D for 24?</p>
<p>did you guys get mean<mode<median?</p>
<p>is 3 wrong 2 skip still 800?</p>
<p>No it’s mode=125, median=126, and mean=127 so mode<median<mean</p>
<p>@cherryblossom:
I did
(abs(b)-abs(ab))/(a-1)=(-b-a(-b))/(a-1) (since abs(a)=a and abs(b)=-b), then … = -b(1-a)/(a-1)=-b(-1)=b</p>
<p>@mickey I scrolled back in my calculator history and the set was 125,125,126,128,131… So mode: 125 median: 126 mean: 127…
therefore
mode<median<mean</p>
<p>what about imaginary root?</p>
<p>if it has x+ yi , then equation will also have -x-yi ?</p>
<p>@ashiej7 & @battlebrick:</p>
<p>What question had 155 as the answer?</p>
<p>Ti 89 titanium on this test just destroys half the questions haha</p>
<p>@doctoribach
no it would be x-yi</p>
<p>@doctoribach:</p>
<p>No, it will have x-yi. The answer was 2-3i.</p>
<p>@melzid i dont know the number but it was the one where n=1.05n(n-1) and you had to find n(10)</p>
<p>@g17xc:
can you remember the actual mean, median, mode question?</p>
<p>How do you scroll back in your calculator history besides 2nd enter</p>
<p>@steve I have mine set to list the past 99 things I did so I can just scroll up… Mine’s a ti89 titanium though.</p>
<p>@whatkneww</p>
<p>yes thats a raw of 44 you need 43 for an 800</p>
<p>so 3 wrong 2 skip- 800? or 790?</p>
<p>Any idea how to do it on the older TI Calculators?</p>
<p>@haters:
The recursive sequence was actually a sub n=1.05(a sub n-1) and you were given that a sub 100 was 12,500. It’s basically a geometric sequence with ratio 1.05 and 100th term 12,500. The 10th term would be 12,500/(1.05)^(100-10)=154.84.</p>
<p>Wait, is that the question people were saying 155 was the answer to?</p>
