O The graph shows a proportional relationship because it is a line, and the difference between each point is the same.
The graph shows a proportional relationship because it is a line, and each x-value is a multiple of 2.
The graph does not show a proportional relationship because each point written as a ratio gives a different value.
O The graph does not show a proportional relationship because a line that increases by 1 in the y-value cannot have a
constant of proportionality.

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?

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.
