The number (in millions) of employees working in educational services in a particular country was 14.4 in 2005 and 18.8 in 2014. letx=5 correspond to the year 2005, and estimate the number of employees in 2011. assume that the data can be modeled by a straight line and that the trend continues indefinitely. use two data points to find such a line and then estimate the requested quantity let y represent the number of employees. the linear equation that best models the number of employees (in millions) is (simplify your answer. use integers or decimals for any numbers in the equation. round to the nearest hundredth as needed.)

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?
