<p>yea i put 2 for that one…</p>

82

<p>

I can confirm that it said “contains”</p>

<p>

That one set of linear equation ones.</p>

83

<p>jhjun: yea i immediately looked at that and crossed it out…</p>

84

<p>any way i look at it, only 1 question missed so far…i think 6 omit = 800 right?</p>

85

<p>what did you guys put for the question that asked, for wat value of x can f(x) = 0?..it gave like f(2)=-3, f(3)=6</p>

86

<p>i omitted that question also. Had no idea, i calculated 2.67 or something like that but it wasnt a answer choice.</p>

87

<p>Oh yeah that one… i said 0…?</p>

88

<p>

It was f(2) = -3, f(4) = 6, so f(3) has the potential to be zero since it the change from -3 to 6 has to make it cross the x axis somewhere in the interval (2, 4).</p>

<p>

Didn’t have to be a linear equation.</p>

89

<p>catcat18: yea that’s what i guessed too…</p>

90

<p>oooooh semaphore i get it. darn</p>

91

<p>damnit…2 missed</p>

92

<p>Probability was 7/15 right?</p>

93

<p>hkim: yes it was</p>

94

<p>hkim yep 7/15</p>

95

<p>What was the probability question?</p>

96

<p>Does anyone remember the first question of the test?</p>

97

<p>what about the 3space perpendicular one?</p>

98

<p>i said infinite</p>

99

<p>Probability of picking a mutliple of 3 and 5 between 1 and 30.</p>

<p>chance of pciking i said 1 :/</p>
