Last month, the soccer team held a bake sale to raise money for new uniforms. They did not raise enough money, so they organized a car wash. The table below shows the number of cars washed and the total amount of money raised by the soccer team, including the amount raised from the bake sale. Fill in the empty values in the table (| | = the empty spaces, its hard to put it in a table format using only text)

Number of Cars Washed Total Amount Raised

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?

Add: (6x^2-5x+3) + (3x^3+7x-8) a. 9x^2+12x-5 b. 9x^2+2x+11 c. 9x^2+2x-5 d. 9x^2-2x+5

If jobs arrive every 15 seconds on average, what is the probability of waiting more than 30 seconds?
