Answer 1

hiya!

Answer 2

hi

Answer 3

u have a question?

Answer 4

can you help me? Im stuck on a math problem for school...

Answer 5

post the question here, and i hope its not due tmorrow plz, i gotta go to bed too lol

Answer 6

Manufactures are installing fewer smaller rims in favor of larger rims. One advantage of bigger rims is that they are better for braking. The following table lists the increase in 16 inch rim sales as a percentage of new vehicle sales for selected years from 1996 to 2002.
Sales of 16 inch rims
Year 1996, 1998, 2000, 2002
Percentage 28, 36, 43, 51
1)Plot the data in a scatter plot
2)Calculate the slope between consecutive points in the table. Intercept each slope.
3) Find the equation of a line that models the data. (Hint: you may want to use the point- slope form, y-y1=m(x-x1))
4)Does your line model the data exactly? Could a line model these data exactly? explain
5)Use your equation to write a function P that models these data.
6) Evaluate P (1999) and intercept your results.

Answer 7

I dont need the whole problem. I only need # 5.
I cant figure out what function P means...

Answer 8

u know how ur line is y-y1=m(x-x1), just solve it for y and that will be ur function P

Answer 9

That's it

Answer 10

Thats what Im stuck on

Answer 11

post the equation that u got

Answer 12

how do I know what to put in for y and y1 and stuff?

Answer 13

run the linear regression

Answer 14

Well, Im not really sure what I got. I plotted the info on a graph. Then I determined the intercepts somehow, but I dont know if they are right. Im sorry, Im so stupid with this stuff.

Answer 15

can i just post the answers?

Answer 16

between 28-36 i got 2/4 or 1/2

Answer 17

Thts fine. Its a team assignment, so I only need number 5. I just cant figure out how to get there.

Answer 18

i have been working on this one problem for 4 hours now...

Answer 19

hello? Are you still here? Anyone? Please..

Answer 20

i am

Answer 21

workin on it

Answer 22

oh, Im sorry. Thank you so much for your help. I am so frustrated and tired.

Answer 23

so am i, okay ill just use:
x = 1996
x1 = 2000
y = 28
y1 = 43

Answer 24

okay...

Answer 25

M = (28-43)/(1996-2000)

Answer 26

M = -15/-4 = 15/4

Answer 27

y - 43 = (15/4)*(x - 2000)

Answer 28

y = 15x/4 - 7500+43

Answer 29

y = 15x/4 - 7457

Answer 30

P(x) = 15x/4 - 7457
P(1999) = 39.25 (plug in 1999 instead of x)
