<p>oh for the geometric sequence problem, the first one is 3 right?
LOL i didn't understand the ratio of 2 part...
it just meant
48-->24-->12-->6-->3
right? -_____-</p>

82

<p>Yeah, it was 3.</p>

83

<p>"as for the last one
it was |x+3|<5
i put down x is less than 5 away from -3, or whatever that one was; B?
is that right? my dad agrees with me lol"</p>

<p>No. I am almost positive that that is not right. I graphed it and did not get that</p>

84

<p>Oops. i also misread the question and put three (for the gloves)
damn, are you guys SURE its four?</p>

85

<p>R R G G B B (Or whatever the colors were)</p>

<p>pull a R
pull a G
pull a B
the fourth one will give you a match</p>

86

<p>No, about the answer. I thought it asked you how many you needed to pull out before you were sure that the next one was matching. </p>

<p>Either flyaway and i did it wrong, or you did it wrong. O_O
Or the directions. AH THE DIRECTIONS.</p>

87

<p>well think about it
|x+3|<5
that means -8<x<2 right
so then x has to be less than 5 off from -3
oh well</p>

88

<p>Either way, i don't quite remember the directions and i'm sure you don't remember it exactly so we'll just look at the score :)</p>

<p>I just want an 800...lol.</p>

89

<p>don't worry too much about it.
the people here (most likely) didn't get all of them right.
we all put our answers because we thought they were right; and some of them are probably wrong. </p>

<p>All we can do now is wait for the results.</p>

90

<p>Agree or disagree?
Math level 2
1) the f(100) pattern problem: value is 1?
2) the isoscleless triangle, I think is 84.1 or something around there?
3) the absolute value problem was it A? distance between x and 3 is less than 5(?)
4) the probability that the sum is greater than 5 with inclusive intergers 1 to 10 and with replacement? (0.5)</p>

91

<p>^
1. agree
2. agree
3. disagree. its definately B, according to my math teacher; |x+3|<5 means distance from -3 is less than 5
4. no its 0.9</p>

<p>kissthesky:
Either flyaway and i did it wrong, or you did it wrong. O_O
Or the directions. AH THE DIRECTIONS.</p>

<p>im pretty sure we did it wrong. my friend also got 4. but then again, he couldv gotten it wrong too -_-
darnit, i wish i rememebred the directions</p>

92

<p>Also what score should I expect with a raw score of 35?</p>

93

<p>^princeton book says 720</p>

<p>i think im going to sit here until i can make up my mind to cancel or not hahahahha xD</p>

94

<ol>
<li>don't remember. </li>
<li>? dont remember</li>
<li>Agree. I got A. </li>
<li>I don't remember.</li>
</ol>

<p>:)</p>

95

<p>ok, flyaway. Your right, I misunderstood the problem. B is right. I got .9, too</p>

96

<p>flyaway what question you referring to about '4'?</p>

97

<ol>
<li>agree</li>
<li>i dont remember this problem at all</li>
<li>i put B, but after reading the other posts.. i'm not so sure anymore =( </li>
<li>i put 0.9</li>
</ol>

98

<p>4=# of draws pairs of mittens or socks or watever with RGB</p>

99

<p>that one question asking if the 2 sets had the same mean, range, and standard deviation.. </p>

<p>can someone explain the answer to me? thanks. </p>

<p>i think the numbers were 0, 2, 4, 6, 8 for one set, and 3, 5, 7, 9, 11 for another.</p>

<p>i think i got confused about the definitions of range and standard deviation.. =/</p>

100

<p>Yeah, it was .9 b/c there are only 10 ways for the sum to be less than/= 5. 10/100= .1</p>

<p>1-.1=.9</p>
