<p>GalindatheGood</p>

<p>It was just a 1/x function.</p>

<p>The image is here <a href=“http://www.sagemath.org/calctut/pix-calctut/onesided05.png[/url]”>http://www.sagemath.org/calctut/pix-calctut/onesided05.png&lt;/a&gt;&lt;/p&gt;

<p>what was the 1 and 6p question about again?</p>

<p>and was it pairs of factors?</p>

123

<p>Thanks! </p>

<p>Do you guys remember the problem with the bar graph and the answer choices were 3.2, 4…and the y-axis had 100, 200, 300, 400 and they were asking for the arithmetic mean?</p>

<p>And there was also a question that said: How many people over the age of 85 (something, something)…I think I got 4 for that one…is that right???</p>

124

<p>anyone get 6 for one of the grid ins? I don’t remember the problem, just that I put down 6 :/</p>

125

<p>THere goes my 800! I got the 6p question wrong, the answer was def. 8! STUPID ERRORS !!!</p>

<p>@galinda
The answer was 3.2 the mean basically</p>

<p>I got four for the old person running problem too</p>

126

<p>I’m pretty sure it said just factors.</p>

<p>So that’s 3 wrong :(</p>

<p>Anyways compared to Jan:
Math as a whole was harder, there were some VERY easy questions but there were also a few very hard ones. Also there were a lot of problems where if you read one word wrong it threw everything off, so that was tricky.</p>

<p>Writing was generally the same in my opinion, essay was better (for me)</p>

<p>CR - vocab was harder than Jan but the passages were easier</p>

127

<p>lalala321 I’m pretty sure it was asking for FACTORS, not pairs of factors. And I got 8 for that one.</p>

<p>p=5
6p = 30</p>

<p>1,2,3,5,6,10,15,30</p>

128

<p>@GalindatheGood I got 3.2 for the first thing, and 4 for the second</p>

129

<p>I think this will be the curve</p>

<p>-1 = 780 in math
-3= 800 in reading
-1 w/ 10 essay = 800 in writing</p>

130

<p>I got 8 for the factors… omg I will be so upset if it said “pairs”</p>

131

<p>Pretty for it was something like this:
P is a (positive) prime integer, where factors of P are only P and 1. How many factors does 6P have, including 1 and 6p? (I put down EIGHT.)
And…
Inverse proportion is k=xy, so rearranging it gives you y=k/x. If k is 1, y=1/x is the correct graph!</p>

<p>And what’s with the f(c) and g(c)? Was that experimental or some problem I forgot about?</p>

132

<p>Did you all get 60 degrees for one of the degrees questions?</p>

133

<p>@lan</p>

<p>The answer to f(c) was 100% 0. I checked 6 times</p>

<p>@galinda
Yes</p>

134

<p>25 was the answer to the area of the shaded portion question?</p>

135

<p>Ugh…I’m trying to remember other problems! So far I know that I got 25 correct and 1 wrong…now I just have to remember the other 28 problems!</p>

<p>Ooooh!!! What was the answer to the Q(t) = 1/2^60/t or something?</p>

136

<p>@GalindatheGood
2 I think.</p>

137

<p>@Galinda </p>

<p>2 I think</p>

138

<p>It was Q(t)=p(1/2)^t/10</p>

<p>Answer was 2.</p>

139

<p>Thanks @zzzzzz1027 :)</p>

<p>OH! And do you guys remember the one with a line on a graph touching a circle, and the question says there is a tangent to the circle and they ask for the area?</p>

140

<p>^4 for that one</p>
