In roulette, you may bet whether the number that comes up is odd (or even). (Remember that 0 and 00 do not count as either odd or even and there are numbers 1-36.) The wager pays even money, that is, if you win, you get whatever you bet, and if you lose, you lose that same amount. What is your expected value for this bet? (Round your answer to one decimal place.)

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

1. perpendicular

2. parallel

3. perpendicular
