<p>it asked for which had a std dev of 0. i put the graph with only 1 bar</p>
<p>as for probability, there was the one about drawing out 3 marbles or something in order.
i put (1/3)<em>(1/2)</em>(1/1) = 1/6</p>
<p>1/6 for probability
and standard dev was A which was the one with only 80</p>
<p>the answer for standard deviation was choice A where there was only one bar on the graph (every score was 80, sd=0)</p>
<p>For the probability one I got 1/6.</p>
<p>Standard deviation is a measure of how far, on average, a point deviates from the mean. If all the points are the same, the standard deviation is 0. So the graph with only one bar had the standard deviation of 0</p>
<p>it was f(x/2) = sqrt( 1 - f(x) ) / 2
and they said if f(a) = 0 then what was a/4
i think you just plug in 0 and solve for x/2 and then divide by 2? not sure, i think i put something along those lines too</p>
<p>the conjugate thing on graph was A…the one with G F or something
and 19 for the log n/ log 2 problem
4 years - the 5.7 million and 1.5% increase</p>
<p>One of the questions towards the end was three different variables multiplied together, with exponents 2,5, and 7 (I think)… I ran out of time so I guessed, anyone remember the answer?</p>
<p>Probability was 1/6</p>
<p>Standard Deviation was A), the one with one bar.</p>
<p>yeah the one about 3 distinct primes. How does one do that?</p>
<p>Oh and what was the answer for the question asking which table had y as a function of x? :|</p>
<p>I chose A for standard devience</p>
<p>What about one towards the end, 3 sin * = 3 cos sin * or something along those lines?</p>
<p>what was the period for the f(x)= 3sin(pi x) + 2cos(2pi x)?</p>
<p>it was p^3q^6s^9 or something along those lines
i actually plugged in primes and double checked xP</p>
<p>period was 2</p>
<p>what was the period for the f(x)= 3sin(pi x) + 2cos(2pi x)?
^
I said 2, not sure if that’s right though.</p>
<p>I got 3 for the period.</p>
<p>i graphed the period question and got 2</p>
<p>I confirm period of 2.
As for the tables, i put I and II because the third one had the same value for y. (1/2 i think). And that voids rules for being a function methinks.</p>
<p>it was a*sec</p>
