<p>These questions are from the blue book 2. They are from Test 5 Section 8 and are questions 6,15, and 16.</p>
<p>For question 6, I read the explanation on CB and i understand why the answer is B, but if i were to see this question again i would not be able to solve it because i do not really understand the y=g(x) and g(k)=1 part. Can someone clarify how to interpret the function?</p>
<p>For 15 and 16, I just do not understand at all.</p>
<p>Post the questions and I’ll answer them for you, I can’t be motivated to go and look at them myself :)</p>
<p>their graphs and pictures :\ sorry</p>
<p>bump please…</p>
<p>can you post the question here,is it long</p>
<p>they consist of graphs, and pictures</p>
<p>bump… i understand 6 and 16 now. Can anyone just explain 15 for me?</p>
<p>If you can’t post the graph, just post the question. If you do that, maybe we can answer it w/o the graph/pic.</p>
<p>Prob.15 requires understanding of scatter plot. Have you learned from school? if not, take a look from google. It’s easy to understand.
you see 12 dots on the graph. They represent the 12 hamsters.
For example, two hamsters practiced once, used 40 s and 45 s. two other hamsters practiced twice, used 42 and 48 seconds. two others practiced three times, used 40 and 45 s. etc.
If you understand this, you can see b, c, d, e are all wrong.</p>
<p>For example, why is b wrong - b/c it would mean practice once (p = 1) use one second (t(p) = p = 1).</p>
<p>cool!..</p>
<p>this is an intereting problem even though it’s easy if you understand the scatterplot. it shows the hamsters who practiced five timesshow no improvement compared to those who practiced once. haha, what’s the point of practicing?! luckily (hopefully) we’re not like the hamsters. lol</p>
<p>lol, I wonder how our hamster thinks about this research, if he could “think”, i.e.</p>
<p>i did learn the scatterplt but i do not see why bcde are obviously wrong. If you plug in some coordinates into some of the answer choices, they can be right. For example, 1 practice and 45 sec fits into choice e. but thats not the answer. on the other hand, some of the choices do not fit into choice e but other functions</p>
<p>choice b: t(p) = p, which means, for example, if p = 1, than t(1) = 1. obviously wrong.
choice c: t(p) = 44p, for example, t(2) = 88, (practice twice) obviously wrong.
choice d: t(p) = t/44, for example, t(1) = 1/44, (one practice) wrong.
choice e: t(p) = p+44, that means more practice gives longer time. which is not demonstrated by the data.
Only A is the best estimate. </p>
<p>The point of this research shows, as luv2sk8 realized, the practice time does not make the hamsters remember things and get out faster. </p>
<p>If it was human, probably it’d be something like this:</p>
<p>t(p) = 44/p, or t(p) = 44 - p, which would mean: more practice, shorter time to get out.</p>
<p>but then for letter a, similar to the ones you just showed, it is 1=45 if you use one of the first dots…tahts waht i dont understnad.</p>
<p>No. for choice a, you get, no matter what p is (no matter how many times it practices,) time is a constant - never changes. It’s always 44 seconds.</p>
<p>but doesn the seconds change on the graph…for example, for number of practices 5, there are three dots. 40,45, and about 47 secs.</p>
<p>the question says "which of the following function BEST models… " It’s not an exact answer, but the best model among the five choices. THe other four don’t make sense at all. agree?</p>
<p>mm i think so… thank you</p>
