Math Makes Sense 5 Homework Book Essay On Voodoo In Haiti
And then made a stem-and-leaf plot to show the data. Understand we have 0, 1, 2 under leaf you have all of these digits here. And once again, what was useful about this, is you see how many players scored between 0 and 9 points, including 9 points. How does this relate to the number of points each student, or each player, actually scored? How many scored between 10 and 19 points, and then how many scored 20 points or over. But let's actually answer the question that they're asking us to answer. So here we just have to add up all of these numbers right over here. 8, 11, 11, 12, 13, 22, 29, 29, and then 29, 36, 40, and 42. The 4 in the number 5,634 is blank times blank than the 4 in the number 12,749. How many times less is the value of the second 7 than the value of the first 7? Well, we already know that the first number is 10 times larger than this number right over here.So let's think about what they're saying. So the second 7 right over here, that's in the ten thousands place. Fill in the following blanks to complete the relationships between 25,430 and 2,543. So literally, if you divide the smaller number into the larger one, you're going to get 10. So that was the first part of the question, and we are done.This is going to be equal to-- in the numerator, we just multiply the numerators. And in the denominator, we just multiply the denominator. And so the numerator is going to be 8, and the denominator is going to be 15. 8 and 15 don't have any factors common to each other, than 1, so this is what it is. Which I could do a little bit better job making those equal, or at least closer to looking equal.
But these are the actual scores for those seven players. And then only one score scored points to started with a 2, and it was actually 20 points. And then this player also had a 0 in his ones digit. So I'm going to actually write down all of this data in a way that maybe you're a little bit more used to understanding it. So there's, let's see, 1, 2, 3, 4, 5, 6, 7 players had 0 as the first digit. This player, I'm going to try to do all the colors, this player also had a 0 in his ones digit. And the way to interpret a stem-and-leaf plot is the leafs contain-- at least the way that this statistician used it-- the leaf contains the smallest digit, or the ones digit, in the number of points that each player scored. And usually the leaf will contain the rightmost digit, or the ones digit, and then the stem will contain all of the other digits. And then finally, you have this player that has the tens digit is a 2. So we're going to add up, I'll start with the largest, so 20 plus 18 plus 13 plus 11 plus 11-- 13, 11, 11-- plus 9 plus 7 plus 7 again plus 4 plus 2. We have two 11's, then a 9, then two 7's, then a 4 then a 2, and then these two characters didn't score anything. So 0 plus 8 is 8, plus 3 is 11, plus 1 is 12, plus 1 is 13, plus 9 is 22, plus 7 is 27, 34, 38, 40. Looks like I actually might have messed-- let me do that one more time. And what's useful about this is it gives kind of a distribution of where the players were.
