  1) Why mention Mr. Robert (or Mr. Roberts)? He's not familiar to us.
  
  2) How can we expect to know whether there is more than one number that goes
  with a student?
  
  3) You asked for help, but then you asked for the answer. You don't understand
  the difference between those two questions, do you?
  
  4) Why would you be stubbornly/persistently lazy not to give an attempt
  and/or ask a pertinent question so that any of us would know where you're
  stuck.
  
  5) Oh, and please do not come back in a later post and state that you
  figured it out (as you have done so many times in the past).

How do you know that i didn't try... why don't u get off my back! i just stated the question, which had Mr Roberts in it. And at this point i want someone to tell me the answer and/or show me how to do the problem. And i told you where i was stuck, i had figured out the whole problem, except how to get how many students in class. i said that in my question. I told you the question, so i don't know how u would know if there is more than 1 number for 1 person, and i don't get that, why would there be? you don't make sense, and unless you wanna help, don't post in this thread.
p.s. i worked on the problem for quite a while before i posted here.

look, i posted that i figured it out, cuz sometimes my dad can help me, and we do it together and i get the answer, and i didn't want someone to spend forever on the problem to help me, when they didn't have to. I was just trying to be nice. there might be others here with a different opinion u got a problem with all of the above, cuz i don't see anything wrong with being nice.

You are being rude. It is polite to be polite to your employees, but the people here are not even your employees. They provide help for free subject to certain expectations of your behavior, one of which is a certain degree of respect and courtesy for people who are trying to help you.

It is expected that you will provide either an accurate summary of the problem or the problem itself. Otherwise we are guessing at what the problem is. If you are seriously confused by the problem, it is highly probable that you will be unable to provide an accurate summary. What is the problem exactly?

It is expected that you will show either work or at least explain what ideas you have thought about. I believe you that you have thought for quite a while about this problem and have produced a stem and leaf plot, but you do not show it so how do we know how to interpret it. Because we do not know the problem, how would we know whether it is the correct plot?

You have posted here now many times. We can expect that you know and will do what is expected of you in return for help.

Edit: I understand why you explain that you no longer need our help. That is indeed thoughtful. It would be even more thoughtful if you explained the answer you got to help other students who may be wondering about the same or a similar problem.

sigh, sorry, when im frustrated i get very irritable.

OK Let's start over. What is the problem?

By the way, it is not uncommon to find that when you take the time to write the problem out and to explain your work, you will suddenly see the solution or where you went wrong. In that case, a brief explanation that may help other students would be nice.

lilybeth,

the title of the thread mentions a stem-and-leaf plot.

Was there a stem-and-leaf plot where you read these numbers off of, such as the following?


\(\displaystyle 6 \ \ \ 1 \ 7 \ 8\)

\(\displaystyle 7 \ \ \ 3 \ 7 \ 8 \ 8 \)

\(\displaystyle 8 \ \ \ 0 \ 1 \ 1 \ 1 \ 6\)

\(\displaystyle 9 \ \ \ 1 \ 2 \ 2 \ 5 \ 9 \)

\(\displaystyle 10 \ \ \ 0 \ 0 \)



Or, was part of the exercise to construct a stem-and-leaf plot for the data in your list?


- - - - - - - - - - - - - - - - -


Also, I do not understand why you wouldn't add up (or see to add up) the number of entries
in the list to get the number of students.

At this point, I don't know if the answer to your question has some trickiness to it.

i just told u the numbers to the stem-and-leaf plot because i already figured that part of the problem, the stem-and-leaf plot looked like this: ^^^ (jeff)



Stems Leaves
6 179
7 3788
8 01116
9 12259
10 00

^^^^^^^^^^^^ sorry, that's my best attempt at typing a stem-and-leaf plot.

anyway, 6,5 (s,l) = 65
so how many students are in Mr. Roberts's class? 16, 19, 21, or 24?
can someone tell me how to pick up from there? thanks.

Count the number of leaves. That's how many students there are. I got 19.

 

[lillybeth]

Thanks srmichael! I got 19 also, and that was the correct answer. .
THANKS!!!!
