can someone give me an example of what they mean about this problem. I have to come up with a real-world example where we can apply the concept learned within our chapter that the data could be linear which it talks about solving equations using the method of least squares within linear functions. then explain it but i have no idea how to set it up. I think it would be something of companies data.But i have no clue how...
can someone give me an example of how can one apply any concept (determining the slope and equation of a line, applying linear functions to mathematic applications, solving equations using the method of least squares) in order to decide if data are linear.Since this is not my area of expertise, I searched Google under the key words "slope equation line" to get these possible sources: http://www.wtamu.edu/academic/anns/mps/math/mathlab/int_algebra/int_alg_tut15_slope.htm http://www.purplemath.com/modules/slope.htm http://id.mind.net/~zona/mmts/functionInstitute/linearFunctions/lsif.html http://www.mathwords.com/p/point_slope_equation_of_a_line.htm http://en.wikipedia.org/wiki/Slope You can find the remaining information you desire, if you...
Can someone help me with this problem? I think I am missing a step somewhere and I cannot figure out where. Find the slope and y-intercept by writing the equation in slope intercept form and graph. 3x+y=-2 Would you consider the y a 1? Thanks
Could someone please explain to me how to work this type of problem. I have tried to figure it out and keep coming up with the wrong answer. Find the slope and y-intercept by writing the equation in slope intercept form then graph, -4x-3y=6 I am totally stuck on this one Please help. Thank You
can someone please correct this for me. i have to graph: y = 3/4x + 2 so the points i got for plotting is: (-4,-1),(0,2),(4,5) then i just connect the points to get the line.If they plot on a line the answer is correct. y= 3/4 x + 2 is a line, and all solutions have to be on that line.yes they are thank you
I have a question about residual plots and regression equations. The data is: X Y 1 6.1 2 5.5 3 9.8 4 10.6 5 14.2 6 21.5 7 29.9 8 37.2 9 50.6 10 64 11 77.6 What function fits this data the best, between Exponential, Linear, Quadratic, and Power. Also how do you make residual plots on a TI-83 Graphing Calculator? Thank you so much for your help in advance. This is crucial to my grade. First, graph it...
Could someone please answer these questions for me. It is for a grade and due on Tuesday, 4/24/07. The license fee for a car varies directly with the value of the car. The fee for a car that is valued at $19,500 is $292.50. a) What is the constant of proportionality? b) Write the equation that shows the license fee as a function of the value of the car. c) If you were to draw the graph of this function,...
can someone show me how to do this one i have plenty of them so can you show me step by step when someone gets a chance. Thank you. Solve the system by graphing x+y=3 x+y=-1What I would do is to put the equations in slope intercept form: y= -x + 3 y= -x -1 Then graph the lines, and see if they cross. If they intersect, that is the solution. In this case, both lines have the same slope,...
Hello! I am hoping that someone can provide me with an example for this question. I am supposed to write a confidence interval problem (not solve it) using this option-- "Think about a population mean that you may be interested in and propose a confidence interval problem for this parameter. Your data values should be approximately normal. For example, you may want to estimate the population mean number of times that adults go out for dinner each week. Your data...
Fitting a Line to Data The method of least squares is a standard approach to the approximate solution of overdeter- mined systems, i.e., sets of equations in which there are more equations than unknowns. The term "least squares" means that the overall solution minimizes the sum of the squares of the errors made in the results of every single equation. In this worksheet you will derive the general for- mula for the slope and y-intercept of a least squares line....
