Best ResponseYou've already chosen the best response.0I got that, but I thought it was 0.

Best ResponseYou've already chosen the best response.0Its supposed to be the y intercept of a graph I'm working on, and it intercepts y at 0,0

anonymous

Best ResponseYou've already chosen the best response.0not really. Here's what it looks like: http://img269.imageshack.us/i/grapheo.png/

Best ResponseYou've already chosen the best response.0the trendline intercepts the y axis at 0,0

anonymous

Best ResponseYou've already chosen the best response.0did you make that graph or is it part of the problem?

anonymous

Best ResponseYou've already chosen the best response.0The problem is I have an answer for the yintercept of the equation (4.3, which I don't want to know), when I need to know the yintercept of that graph, which I think is 0,0

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0no, that graph looks like it is going to intersect the y axis at about 4.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0you made that graph based on your equation, right?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0why don't you extend the line on the graph and see where it meets the y axis?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I did make it based on my equation, and i did extend the trendline.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0the trendline hits 0,0

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0if you made the graph based on your equation, then it will automatically intersect the y axis at 4.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0No, you must have made some mistake. if the line on the graph is the equation, then it has to intersect the y axis at 4.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0actually, it will hit the y axis at 3.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0because your x axis includes the teacher

anonymous

Best ResponseYou've already chosen the best response.0wait, what is your input? Is it the number of students ?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0how do you reckon I can fix this?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0number of students +1 teacher

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0its the number of the students plus 1 teacher, and the other value is the total cost of the movie tickets for that amount of students + 1 teacher.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so lets call that class size. so the x axis is the class size. and the y axis is the cost. what is 3.3?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I'm not sure anymore. Its linear: C$=11.5 x N+ 1 + 3.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0see, your input cannot be N+1. It is either the number of students alone or the number of students plus a teacher, who is always present.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0if you are taking your input as the total number of people who are going to the theater, then it should not matter if one of them is a teacher.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0but if you are taking the number of students alone as your input, then you have to do the N+1 business.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0wait I think i get it now, so N should be students +1 teacher

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.01 teacher is always present no matter what. Its only the number of students who change.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so, if the number of students is 0, the teacher still ends up going to the theater by himself and pays the adult ticket price. which is 11.5 +3.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0i think the 3.3 is additional charge for adult.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so your y intercept should be 14.8, where your x axis is the number of students alone(not including the teacher)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0i think you're right abuot the 3.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so then total cost is y = 11.5(N+1)+3. that is, 11.5 dollars for each ticket for all the students and teacher, plus 3.3 for the adult charge.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so plot your graph with x axis as the number of students alone.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0then your y intercept will be if no students come for the class movie trip, that is, the adult teacher alone goes. so he will be charged 11.5 dollars, which is the charge for everyone +3.3 dollars for being adult.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0please let me know if I have clarified your doubt. If there is no feedback, I cannot know whether to continue explaining or not.

Best ResponseYou've already chosen the best response.0how can i put that in a two column table

anonymous

Best ResponseYou've already chosen the best response.0Thanks for your help btw, I appreciate it.

anonymous

Best ResponseYou've already chosen the best response.0input (# of students N)  output (Cost) 0  14.8 1  14.8+11.5 ...... and so on

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0n of students (+1 teacher)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0N is a variable, right? the teacher is always present. so he is constant. Only the number of students changes.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I gave you the equation too: y = (N+1)11.5 +3.3 y = 11.5N +14.8

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yeah i know the 1 teacher is always present, always constant, and the number of students changes

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0right, so what is the confusion?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0What title i have for that column

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Total Number of Students + 1 teacher

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0and below that, '1' because theres 0 students, but 1 teacher

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0X axis is the number of students. x axis is the independent variable. y depends on x, so y axis is the dependent variable. the titles of x axis and y axis should be # of students and Cost, respectively.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0note that there is no xintercept for this equation.

anonymous

Best ResponseYou've already chosen the best response.0ill change that now...stay here though I reckon ive got more questions

anonymous

Best ResponseYou've already chosen the best response.0Quick question, what is$11.50 after a 10% price rise? and $14.80

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0cent = century = 100. percent = per cent. per = for every. percent = for every 100. so if your share of profits is 10percent of total profit, it means you get 10 dollars for every 100 dollars the company makes. so you make 10/100 of what the company makes.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So if your company makes 200 dollars profit, and your share is 20 % of the profit, you make 20/100 of 200 = 20 dollars.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0$12.30? Is that the 10% price increase?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0sorry, that should have been 40.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0$11.50 + 1.15= $12.65 ?????

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0wait my mistake, $12.65

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0similarly find 10% increase in 14.8

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I went 10x11.50 and then the % button

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0then added that to 11.50

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0understand what percent means and you wont have any confusion even if you have to do it without a calculator. see above.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0So I go 10 for every 100, divide 14.80 by 10. I remember that, just jump the decimal backwards to divide by how many zeros.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0okay so 10 % increase in 14.8 is 14.8+1.48

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Number of Students (+1 teacher)  Cost 1  14.80

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0my maths teacher wanted me to add the +1 to the amount of students+1 teacher column

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Then your variable is not number of students. your variable is class size.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0in that case, it does not have a y intercept.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0this is heaps frustrating for me. its due tonight in the next few hours. and I dont understand much about maths, I'm really poor at it

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0okay, for y intercept ti exist, the class size has to be zero. But the way you have defined your independent variable as (amount of students+1), your variable cannot be zero even if amount of students is 0. Do it my way. It is correct.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Please explain what your way (again!)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0y = 11.5N +14.8 plot that graph. x axis is number of students. y axis is cost.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0or you can do it your way, if you shift the origin from 0,0 to 1,0

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so its Cost=11.5 times Number of students plus 1 teacher's price

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ok, so thats the formula down.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yes, if you do it your math teacher's way, then it doesn't make any sense. The cost would be 3.3 even if no one, including the teacher went.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0How about the table? I'll show you what it looks like now: http://img839.imageshack.us/i/tableup.png/

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0ive been asked to use different numbers of the students, it doesnt have to be 1,2,3,4,5,6 etc.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yes, but if noone goes in your teacher's method, the yintercept is 3.3. So that means that the class pays 3.3 and no one goes, not even the teacher. In my way, if no one goes, it means only the students don't go. The teacher still goes no matter what. My way makes more sense than your math teacher's way.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0Yeah fair point. So what do you suggest I do with the table?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0your table should read class size( teacher NOT included) and use the formula y = (N+1)11.5 +3.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0so for N = 0 , y = 14.8 N=1 y = 26.3 and so on.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I'm using 'Class size (teacher included in price)'

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I guess, though I am not totally comfortable with that. You can argue with your teacher that his/her way does not make sense. you might get bonus points for that.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0its correct, but it shouldn't read that. because it is a variable that you are defining as class size. It has no other attributes.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0hang on, you changed it from y = 11.5N +14.8 to y = (N+1)11.5 +3.3

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0dude, both are the same equation. Think about it before you post this silly stuff.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0its just proper semantics, that's all. y = (n+1)11.5 + 3.3 conveys the proper meaning of the equation.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0i'll stick with y = 11.5N +14.8, we're not using brackets/parenthesis currently in class

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0i added a trendline, and displayed the equation on the chart but it says: y = 11.13x + 11.194 R² = 0.9993

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0i know whats wrong, the class number still had the teacher added.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0now its: y = 11.5x + 14.8 R² = 1 a perfect r2 value!

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0what is R2 ? You can't expect people to know what you are talking about. you seem to be using some sort of software.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0is that good or bad that r2 is 1?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I thought you'd know that! R squared value. I don't know much about it, but I remember that if its 1 its perfect, if its below, its not great.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I probably know it. But i may have called is Z squared. What is R?

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0The yintercept (for the graph) is (0, 14.8)

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0The question says explain why it is this value

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0I say its because its linear, and it has a perfect r2 value, but I dont think thats right

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0it is that value because thats the price of the ticket for an adult. Duh!

anonymous
