Question

@Hero @BangkokGarrett

The box-and-whisker plot shows the weights, in kilograms, of randomly selected packages in a mail truck. Which of the following conjectures does the plot support?

A. The median weight of the packages in the truck is about 50 kilograms.

B. Half of the packages in the truck weigh between 20 and 30 kilograms.

C. There are at least 100 packages in the truck.

D. About three-fourths of the packages in the truck weigh less than 50 kilograms.

Can u explain this? :)

Answer 1

@Hero and @BangkokGarrett

Answer 2

@Hero

Answer 3

Can you explain @Hero ? :)

Answer 4

Basically, all I know is, that vertical line in the box represents the median.

Answer 5

@Hero
The stem-and-leaf plot shows the number of items randomly selected customers in a grocery store bought during its first hour in business.
Which conjecture about the store’s first hour is not supported by the data?

A. The store had 15 or more paying customers.
B. Most customers bought more than 10 items
C. The most common number of items bought was 15.
D. The median number of items bought per customer was 23.

Answer 6

@Hero Do u know this one?

Answer 7

Actually yes. I'm familiar with stem and leaf plot.

Answer 8

Think about what the graph represents then compare that with the answer choices.

Answer 9

It says the Stem and Leaf plot represents the number of "items that random store customers bought in the first hour"

Answer 10

Knowing that, which answer choice doesn't seem to support what the graph represents?

Answer 11

@Hero I'm actually not sure. I'm REALLY bad at these kinda of graphs, I don't even know how to read one.

Answer 12

You don't even really need the graph. You just need to know what it represents. Do you know what the graph represents? Hint: I just said it.

Answer 13

B?

Answer 14

@Hero or is it D...

Answer 15

Put it this way, three of the choices are all talking about one thing, and then another choice is talking about something else that has nothing to do with what the original graph represents. Try to find the one that doesn't go along with the rest of them.

Answer 16

Remember, also what I said about stating an answer choice and then stating why you chose that particular choice.

Answer 17

A? It seems like the rest of them are talking about what they bough. But A is talking about how many customers came in. I think...

Answer 18

There you go. See, all it takes it just a little bit of "thinking" to figure some of these out.

Answer 19

Oh! Yay! :)

Answer 20

As for your question about the pond, I have an approach to it, but the explanation isn't 100% clear yet. By the time you post that question again, I'll have the explanation down.

Answer 21

@Hero I have another one, but it has percents with I'm very confused on.

The bar graph shows the percent of people who voted for each candidate for president of their book club. After a discrepancy is found, a second vote is taken. Which is the best conjecture for the number of votes Sidney receives in the revote if 40 book club members vote?
A. 9
B. 25
C. 15
D. 6

Answer 22

It's another proportion question.

Answer 23

This is the last question I will help you with. I apologize but I have to move on.

Answer 24

Basically, from the graph we can assume that 100 votes were taken and

Sidney received 15 votes
Todd Received 60 votes
Alice received 25 votes

Answer 25

So basically we can represent the number of votes sidney received over the total amount of votes taken as:

\[\frac{15}{100}\]

Answer 26

So if only 40 votes are taken the second time then, we solve this proportion to figure out how many votes Sidney received the second time:

\[\frac{15}{100} = \frac{x}{40}\]

Answer 27

So, A?
I'm sorry, I didn't know I was taking up so much of your time. 0_0 I can find someone else to help wit the rest of them, I'm sorry! :)

Answer 28

Woops I mean C?

Answer 29

Solve the proportion for x

Answer 30

You should have waited for me to finish posting the rest of the proportion before guessing.

Answer 31

Sorry... 6? D!!D!!

Answer 32

Can you help me with just one more? :) @Hero

Answer 33

Face Palm :P

Answer 34

But seriously, I'm getting tired. I have other things I need to be doing.

Answer 35

Oh, OK. 0_0 I'm sorry. I won't take up any more of your time.

Answer 36

But just to confirm, yes, 6 is the correct answer. Try to understand why.

Answer 37

Thanks for all your help!

Answer 38

You're welcome.
