An oven heating element turns on when the internal temperature falls to 20 degrees below the set temperature and turns off when the temperature reaches 5 degrees above the set temperature. you preheat the oven to 405 degrees before putting a cake in and baking it for an hour at 405. write an inequality in terms of the temperature, t, that describes the temperature range of the oven while the cake is baking.

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?
