• 9. Jenny took x number of items out of
the dryer. She folded 10 items and put
them in one pile. Then she folded the
remaining items and divided them evenly
into p piles. Which expression represents
the number of items in each pile after the
first one?

What is the greatest common factor of 8 and 36

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?

How to do this , and can some one explain
