>>714034475
It's not B.

>>714034709
FUCK, WHAT
the pattern i thought was that there had to be two lines of square circle triangle and they had to connect with one shape.

damn it. now i actually dont know what

>>714034709
see, that's the problem with this sort of puzzle
there's a pattern there, all cells have either an L or a T formed by lines with one each of square circle triangle

there's one particular pattern that the puzzle designer is looking for, but there are a variety of possible patterns and solutions

>>714028877
What I was trying to say in this post was that all of the lines are connected, so it is just 1 line so it would be impossible to draw separate lines without lifting the pencil from the page

>>714035304
This supposed pattern doesn't fit, though. There are several rows and columns that aren't marked in this solution. For example, all three horizontal lines in the middle figure has one square, circle and triangle.

Requirements by the statement of the rules are that you must connect the dots by drawing straight lines and not lifting the pencil from the paper, and that you must end up where you started.

Says nothing about no extra non-straight lines, or shit, beyond that no extra straight lines.

just fold the paper when you've finished drawing to get the pencil back to the starting point

True, common use of the word line is to mean sections of lines. As the literal definition of line is applicable mostly only in looking at geometries.

The answer is G next question please.

Also to explain it : Each symbol moves right one space per turn. Triangles turn to Squares, Squares to Os, and Os to triangles.

Correct, well done. I can add that when going from one horizontal line to the next, the entire figure is simply rotated 90 degrees clockwise.

>>714038186
thats just the same thing i did except i used the template and it doesnt look like ass

good try tho anon

>>714038229
Well, it is. The 90 degree change from one line to the next is just a neat detail that's irrelevant to the solution. The reason it's most intuitive to otherwise keep the original orientation is that the change follows the pattern of reading: It goes from left to right, then to the next line below, etc.

>>714037560
To specify, "each symbol moves right one space" means that it moves to the right until it reaches the end, the last object in a row moves to be the first element of the next row, until out of rows, upon which the final object moves to the first row's first element.

even if that was so you have to find the root of 4, which is just... 2

even so, that's the highest on the scale, the lowest would be 0.1 or 0? so the average distance would just be 1

You think the average of all distances between two random points inside of a unit square is 4...?

When there exists no such line inside of a unit square that is greater than sqrt(2) (which is about 1.41)

Round 5, then.

>>714040821
It's not a hard problem, the problem with it is that most people lack the tools to approach it. Knowing probability distributions and the calculus to integrate it is... a bit of a tall order.

Is it √2 / 2? √2 is the longest, and all other random lines must be less than it, with the middle being half of the max?

>>714040938
It does take a bit of cleverness to simplify the quadruple integral, though.

what?

>>714041381
Yeah, let's set up a non-tuple integral and solve it for fun! wooooo.

The formula is basically: for a given object of dimension n, solve the n^2 integral of the distance formula sqrt[(a1-b1)^2+(a2-b2)^2+...+(an-bn)^2] where a represents coordinates of first point (a1, a2, ..., an), and b represents coordinates of second point (b1, b2, ... , bn). With respect to every single element of those vectors, from 0 to 1.

>>714042476
That formula is obvious, the challenge is solving those integrals, which is far from trivial.

The answer is indeed 30. Using the Laws of Sines and Cosines is overkill though, as it can be solved purely through elementary methods, though it's quite tricky.

>>714047073
"quite tricky" nigga why though. law of sines is easy as all fuck to use. Law of cosines I sometimes forget, but can figure it out if i know i need it.

Could essentially create a matrix and solve it with missing variables, but i don't see how that's any easier honestly.

>>714047388
The solution that utilizes only elementary methods is much more elegant and simple (once you see it). It's just difficult to find that solution in the first place.

I guess elegance is in the eye of the beholder. Obviously this trick is nowhere near as useful as knowing the laws of Sines and Cosines; if it was, it would be a technique taught to everyone studying geometry. It's precisely its unexpectedness and esoteric nature that makes it elegant, though.
