The diagram shows the back fences of three houses in a small neighborhood. The lengths of the fences are given. Pythagorean theorem: a2 + b2 = c2

A triangle has side lengths 12 meters, 5 meters, 13 meters.

Use the Pythagorean theorem to classify the triangle formed by the three fences. Which is true about the numbers 5, 12, and 13?
They are a Pythagorean triple that does not form a right triangle.
They are a Pythagorean triple that forms a right triangle.
They do not satisfy the Pythagorean theorem, but they do form a right triangle.
They do not satisfy the Pythagorean theorem, and they do not form a right triangle.

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
