How many leaves does a full 3 -ary tree with 100 vertices have?

You're asked how Maney leaves does a full three area tree with 100 verses have. So we recall that. And a full M Mary tree with an vergis is has Well, l is equal to m minus one times n plus one all over em leaves. So here, um, let's suppose that we have that are our treaty is a full three area tree with 100 verses. So then therefore mm would be equal to three and and would be equal to 100. Okay, so eso therefore, the tree would have to times 100 plus one all over three leaves. So therefore we have what we have 201 201 over three leaves. So but what is, um, leaves okay, but what is 200 or three? Um, that's 67. So therefore, a full three area tree with 100 verses would have 67 leaves right

So we have 49 pieces of data and we want to figure out the percentile rank of the number 800. Now, if you look on that table, we have five dead data values that are less than or equal to 800. So that means our percentile is going to be five out of 49 And we're gonna use a calculator to do that, five Divided by 49. So it is the 10th percentile ish. And now we have to find the percentile rank of 23. If you look on that information, You're going to find 45 data values that are Less than or equal to 2300. So that gives us 45 out of 49. Again, we use our calculator, 45 divided by 49 And that is the 92nd%ile ISH. So it's the 92nd%ile.

Okay for this problem were given little stemming stem and leaf display were asked a few questions about it. So one of the first things we talk about what's called the leaf unit question. They asked, what is the leaf unit? Uh, 0.1 zero. Mean So the biggest thing about stem and leaf graphs is that we're kind of the stem is usually showing the ones or the tens or something. But the leaf is the second digit. So, for example, here just go, right. The first one, the first one is 50. No, I seven. Okay, so I was gonna answer Question A down here is the leaf unit. Quinn 01 Okay, that means that it's hundreds so that the last digit is the hundreds place, because that's where that one is. The non zero number. Okay, I'm gonna fill this in as we go. So if you look down here, um, that's with them asking for hammer you How many data are shown? So there are 16 number showing. I was take a minute. Right? All these out. So 597 And so the six toe 60 there. We're that one time the whole purpose of the stem and leaf is to not have to rewrite things. Okay, I said that would be, um 5.97 is the 1st 16.1 is this is the second one and the third one. And fourth one's work we have to do is just count each of these other two, count out all 15. So take the time to dry all these. That I guess I will. But there, in your book. Okay. So six points there ones explains your 46.8 and then we have I'm just gonna count these as I goes, I 1234 So is our fifth value sixth value, seventh value fell. Unite value, 10th value. 11 12 13 14 15 16. So they're 16 data points or 16 values. And again, I said in my lab, but basically, just count these digits. And you know what the first first digits mean? Um, it was the first four data values. So this is the big one here. So, um, the first four it is Highlight those incredible here. So 1234 So those are the leaves of the first four. So the first four Because we know these air hundreds. Right? So this is 5.97 6.1 6.4 and 6.8 This isn't a little bit more how this looks a little more unusual. Usually, you see the stem and leaf graphs look more like this. Um, but the digits air kind of different here, so but because we know this is hundreds, we're gonna work backwards from there. So the next one party s what does it call him? The number down the left hand side of the figure. Okay, so after the left hand side, I'm gonna put him a screen. We see these numbers? Yeah, one or five. And you can see the other lines. 231 I said, what these are is a cumulative frequency. So what it's doing its counting up how many values there are since we go. So there's one value and there's four values, and then it keeps going along there. There's five more than you kind of can't out. How many there are in each of those cases. So, um, whether the cumulative frequency, I don't see that a lot, but that's what it did. All right, so that is the main part of the problem. So we've got our stem leaf again. Stems this case or two digits and leaves or single digits. But the most important one is probably this question right there. Just male to read off what it is. And sometimes you're asked questions about the meaning media mode, and you kind of interpret what it is and kind of see how they look, like, look like the numbers. You're kind of in a warder. All right, so I hope this helps.

This is problem # 17. We are given the following stem and leaf plot and are tasked with reconstructing the original set of data. Note that in this stem and leaf plot, the stem represents the ones and the leaf represents the tents. So we will begin by pairing each stem with one leaf, repeating for each leaf and then repeating for each stem. So we have 1.2. Remember to cost them out as you go 1416. We have 2.1 2.4 22 sevens At a 2.9. You can continue this for each of these pairs of data points and you will find your full set of data for all of these points.
