The five values for a data set are: minimum = 0 lower quartile = 2 median = 3.5 upper quartile = 5 maximum = 10 A box-and-whisker plot. The number line goes from 0 to 11. The whiskers range from 1 to 10, and the box ranges from 2 to 5. A line divides the box at 3.5.

Click on the graphic until you find the right quotient. (36xa - 30xb) ÷ (-6x2)

Find a number such that if you add 8 and divide the result by 4 you will get the same answer as if you subtracted 3 from the original number and divided by 2

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?
