Dylan works out and burns 10 calories per minute swimming and 7 calories per minute biking. He wants to burn a minimum of 600 calories. Due to daylight limitations, the time Dylan spends swimming must be no less than twice the time he spends biking. Given that x is the number of minutes spent swimming and y is the number of minutes spent biking, determine which inequalities represent the constraints for this situation. x ≤ 2y 10x + 7y ≥ 600 2x < y 7x + 10y > 600 2x ≥ y 7x + 10y ≤ 600 10x + 7y > 600 x ≥ 2y Which combinations of minutes spent swimming and minutes spent biking satisfy this system of inequalities? Select all that apply. (44,25) (46,20) (37,19) (52,12)

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?
