<p>You didn’t read the question it said what percent was the iqr/range not the iqr</p>
<p>so the iqr is 50 percent and the range is 100 percent of the data
so 50/100 = 50%</p>
<p>The prime number one is 8. I did 2x2x2x3 and 3x3x3x2. Both results have 8 factors.</p>
<p>The range is the highest minus the lowest which was like 29-7 or 22ish. My iqr was the higher minus the lower quartile range which wasn’tnear near half of the
Range. I can t explain everything atm cuz im on my phone</p>
<p>I used 5x5x7 for the prime number one so then I got 1 5 7 35 25 175 so it was 6</p>
<p>then it would of been 5 x 5 x 5 x 7</p>
<p>Actually, I got 33% for iqr</p>
<p>what were the answer choices for the iqr question? i think i may have put 31 or something…</p>
<p>Guys, the question asked for the factors that are distinctive. So the answer is actually 4</p>
<p>I got something like that, weiyou</p>
<p>Sorry, didn’t get a chance to reply (not that it matters anyways now). I used Barron’s to prep for my first attempt. My highest Barron’s score was a 720 or something like that (definitely 700+); I got a 750 on the real thing. I also got 800 on the official CB one before my previous attempt.</p>

<p>Just took the exam. It was easier than the December one, but that may be because Dr. Chung’s difficulty over-prepared me. I’m confident I did better than my previous 750; I think I skipped 5-7 and, assuming I didn’t miss any, I’m fairly confident that I got at least 770. </p>
<p>The prime number one is 8. Like I said, 24 and 54 are examples and they both have 8 factors. The question asked for 3 same prime numbers and one distinct as factors of the number like 2 2 2 3 or 3 3 3 2</p>
<p>The test was really easy imo btw what was the law of cosines, the card with 1/2 probability, and fire alarm probability?</p>
<p>Uh. No, you’re wrong. They asked for different positive factors. And 24 wouldn’t work. 2 is an iffy prime number. I used 7,7,7, and 11 and it’s 4 factors. </p>
<p>That question should be thrown out. </p>
<p>7 7 7 11 = 3773</p>
<p>Factors are 1 7 11 49 77 343 539 3773 which is 8. Maybe im misunderstanding something but I still think its 8?</p>
<p>for the law of cosines i got that u needed all the sides, and for the fire alarm i got like 0.92 or something</p>
<p>Actually, you’re right. Damnit. </p>
<p>fire alarm it was .997 because u have to add both of them and subtract the product of the two</p>
<p>I skipped all the probability questions. </p>
<p>weiyourenma is correct.</p>
<p>I got one answer just as time was called; didn’t get a chance to bubble in :(</p>
<p>For the fire alarm, i got .883. Dont you need to multiply them?</p>
<p>How many probability questions were there?</p>
