um at least 2

#2 to #1 - wolfiet [OP](09/26/2015) [-]

He doesn't even know the answer, he spent 40 minutes making that and still doesn't know the answer

#4 to #2 - dezzka (09/26/2015) [-]

yea it's definitely at least 2

#3 to #2 - wolfiet [OP](09/26/2015) [-]

That specific problem, not the whole test

#6 to #3 - musicmic (09/27/2015) [-]

well to be fair he left the circles both have unknown variable that makes it so they cant be solved and the l hole has no variables as well or lines the same size as those nor is the length and height of that rectangle show. in a situation where most of the question is full of unknowns it can't be solved unless if had some rules to go with it like the lines are proportional and you could use the length of one of the sides and a ruler to calculate the distances but that could also require a unit conversion if an untraditional unit is used as apposed to milimeters... sorry if i sound like a buzz kill but im majoring in engineering and have been mathing the **** out of everything. (calculus makes me angry)

-1

#11 to #6 - wolfiet [OP](09/27/2015) [-]

That's an older picture, I'll try to get him to send me the updated one that has the variables and such, alright?

#12 to #11 - musicmic (09/27/2015) [-]

That's cool I might look at it but probably won't do the problem. My guess on a shaded area would be between 60 to 70% just buy the relative sizes of the shapes.

#7 to #6 - wolfiet [OP](09/27/2015) [-]

No problem, I'm glad someone managed to give me a straightforward answer, I've been wrapping my brain around this

#20 - notwalkingwaffles ONLINE (09/27/2015) [-]

A1=area of brown. A2 = area of white. P1= probability of point being in A1.

P1=A1/(A1+A2)

#18 - milnerdk (09/27/2015) [-]

The answer is Elleventy two and five quarters

#16 - bloorajah ONLINE (09/27/2015) [-]

just had an organic chem exam last week, literally nobody in the class finished in the allotted time. Class average ended up being 61%. which is apparently typical.

#17 to #16 - wolfiet [OP](09/27/2015) [-]

Christ, why would they let that one through if almost nobody can get a good grade on it?

#15 - gypsydude (09/27/2015) [-]

Just say 46.82% so you sound smart

#13 - elseano (09/27/2015) [-]

Please correct me if i'm wrong, but the first one is impossible to calculate. Not enough information- you would need to know the various radii of the circle and the length of the sides. as for the second one, I'm pretty sure there's only two tangents that line up.

#14 to #13 - wolfiet [OP](09/27/2015) [-]

Yeah, that was more like the Outline for his test - he's trying to get the picture of the completed one

#19 to #13 - anon (09/27/2015) [-]

The first one is supposed to be the application of monte carlo algorithm. It supposed that the drawing is properly scaled

#8 - niggastolemyname (09/27/2015) [-]

So, are the two questions together supposed to be dickbutt?

#9 to #8 - wolfiet [OP](09/27/2015) [-]

No, but that would be ******* hilarious

I'll try to get him to create a graphing equation that ends up being dickbutt and post it for you next time they have to do this, if you'd like
