<p>Bugyloo@ Exactly!!!</p>

<p>What about the x-intercept in the parabola? Please I need to know.</p>

<p>Its (5,0) im sure…</p>

<p>@LittleBrother001 dude wasnt 88 already in the temperatures?</p>

<p>why 88? the question indeed asked for 7th unknown temperature.</p>

<p>{80, 83, 85, 90, 92, 93, x} and they said median is 88. so 7th unknown temperature is 88.</p>

<p>Exponent problem, I got 16</p>

<p>The k^10 question is 16</p>

<p>what was the question I dont remember it…</p>

<p>oh yeh 16 for the usa debt…</p>

<p>Does anyone know the answer to the question about workers?</p>

<p>What about the question where we had to calculate the area of the triangle (it was inscribed in a cylinder)?</p>

<p>7th day temp is 88 -__- i made it wrong , its tricky</p>

<p>Does anyone remember the answer of number 6 in the grid-in section? The one that asks about the average of the number of students enrolled from 2001 to 2005 in that certain place was how much greater than that of the other one?</p>

<p>@Kyoto2289
if i remember well its 0</p>

<p>It’s not 50?
Cuz the first place each year 100 new students are enrolled
And throughout 4 years , so the total will be 400
And the average 100
As for the second place, each year 50 new students are enrolled, throughout 4 years, =200
So the average is 50</p>

<p>I remember getting something like 16 *10^3 for the exponent problem</p>

<p>Its 5 years & i remember adding the number of students for each line they were the same.</p>

<p>I guess they were only 4 years
Starting from 2001
Until 2005</p>

<p>Oh and did you guys get 60 for the area of the triangle inside the cylinder?</p>

<p>5 points were on each line lol. 2001 2002 2003 2004 2005</p>

<p>Yes I got it 60</p>

<p>Icecubes123: yup 1/2 * 10 * 12 = 60</p>
