Racehorse a man buys a racehorse for $20,000 and en- ters it in two races. he plans to sell the horse afterward, hoping to make a profit. if the horse wins both races, its value will jump to $100,000. if it wins one of the races, it will be worth $50,000. if it loses both races, it will be worth only $10,000. the man believes there’s a 20% chance that the horse will win the first race and a 30% chance it will win the second one. assuming that the two races are independent events, find the man’s expected profit.

$10,600

Step-by-step explanation:

Worth raises to $100,000 by winning both races

Worth raises to $50,000 by winning one race

Worth decreases to $10,000 by loosing both

Probabilty of winning both races=

Probabilty of winning one race==0.38

Probabilty of loosing both races==0.56

Expected profit=

=$10,600

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

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,
