Homework Statement The problem asks to solve for x log(x)=-4x+5 (the log has base 10 - not natural log) Homework Equations The Attempt at a Solution log(x)=-4x+5 10^-4x+5=x log(10^-4x+5)=log(x) -4x+5*log(10)=log(x) -4x+5=log(x) seems at first to be a simple enough...

Hi, I m unsure whether or not this should perhaps be in the homework forum, however one might say this is more of a technical issue. I recently conducted an experiment for a report I intend to write up promptly, and I wanted to find the best fitting curve for these values. I tested how different...

of course! thanks so much after all that i miss that 1 detail haha that's 2 problems you've helped me with, thank you to everyone else that has attempted to help me as well much appreciated everyone! physics forums is brilliant, hope i can someday help others like you have helped me :)

it seemed reasonable to do 40-(37-x)=(37-x)/2 if the yellow is 40-(37-x) and the union of the two sets is 37-x if divide that by two then i should have a functioning equation, right? however that just solves x as being 10.333...

but in order to figure out the yellow i need the intersection don't I? 40-(37-x) must be more appropriate then if i am to use that it adds up to 40

This means that the yellow is 2x and the red is 17-x and then i assume i use simultaneous equations to solve it, do tell me if I'm on the right track, but please no answer^^

but how did you derive the equation a'∩b'=(1/2)(40-(a+b+a∩b))? I would understand if the 1/2 wasn't there, but if the 1/2 isn't there then the whole method doesn't work

so a∩b=3?

I have been considering your suggestions all day in fact but i have not been able to produce the result, sorry if it seems like i have not, i do not want to be given the answer i assure you

where did these come from?

I only end up with equations with a'∩b' included =(

it's no problem, hope your probability works out well :) Though i will have to burden you some more, i do not see how knowing that a+a∩b=20 and b+b∩b=17 helps me just seems like I'm always missing this 1 key bit of information, it is simultaneous equations i am meant to be using correct?

what is this S, how did you form this equation?

but you can't exactly assume that set A contains the elements 1,2...20 and set B contains the elements 1,2...17, can you?

Ughh, i just cannot seem to connect the dots, I am meant to be doing this using simultaneous equations correct? Please don't leave me on my own now need this solved by monday =(
