I have the equation, sales price = 16.0 + 1.90 home size, and want a 95% prediction interval for when home size is 18.
I just need the equation with what I need to solve it! I have all the error and variance numbers to use! Thanks!

Here is the data:
latitude (degrees N), x axis: 6, 18, 23, 30, 35, 42, 45, 52, 56, 56
april mean high temperature (degrees F), y axis: 89, 84, 97, 83, 63, 68, 45, 56, 47, 47
The equation I found was y=-1x+103.
WAIT, is it 0 for the latitude? Or temperature..?
I need to be able to reference the equation of the trend line obtained on a graph in Microsoft Excel 2007.
I know I can just type the equation but my instructor would like the whole process to be automatic. Just change the values and everything should change with it. Including data which relies...

I know what it means when it says 4 ohms to 8 ohms by 4. Thats "a 4 or 8 ohm speaker, PER channel." But then there is this...4 ohms to 8 ohms x 2 + 2 ohms by 1. What does the last equation mean?

Is it not as simple as I thought? We're studying poynomial functions in precalc... do I not have enough math experience to be able to know this already?
How do you write (and transform) the equation for a bell curve? (I'm talking about that thing that looks like 1/4 of a sine wave, but not...
...((x-a)/(x+a))^x =e? I can't get this to work out, i'm thinking it needs to be done using logarithms to simplify it and then l'hoptial's to compute the limit, and then solve for a, but this could be wrong. Any Help would be much appreciated. Thanks
use your prediction equation to? predict the number of comic books sold when the price is $4.50.
Price( 2.00, 2.60, 2.75, 3.00, 3.50)
Number sold ( 16, 13, 12, 10, 7)

i have to make a prediction equation for a series of data (times for the olympic 400m) and then make a prediction about what the winning time will be for 2024. i chose two ordered pairs: (3, 51.08) (10, 49.11). the x-values (3 and 10) stand for the third year and the tenth year. the y-values...
My TI-84 Plus Silver Edition calculator won't graph more than one equation on "Y="?
I don't know what happened but my graphing calculator won't let me graph more than one line at a time. If I enter another line on my next "Y=", it won't show up but it the previous graph will show. I tried...
Okay so for a research project I have scores of tests i carried out on people. I want to represent the scores with a bell curve and I want to be exact by graphing an actual equation rather than just guessing what it would look like.
So could anybody give me the equation for a bell curve and what...
