Estimate the size of a crowd standing along a one-half mite section of a parade route that is 5 feet deep on one side of the street and 10 feet deep other side of the street

Assume that each person occupies 2.5square feet

When are two distinct non vertical lines parallel

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?

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.
