In car racing competition, four car brands A, B, C, and D are competing with two cars each. Each of the cars from A, B, C have the same chance of winning, while each of D’s cars have twice the chance of winning. What is the probability of winning for the D brand?

P(D)=2/5

Step-by-step explanation:

We know that in car racing competition, four car brands A, B, C, and D are competing with two cars each. Each of the cars from A, B, C have the same chance of winning, while each of D’s cars have twice the chance of winning. We get

We conclude that the probability of winning for the D brand is

the answer is c just got it on ed

step-by-step explanation:

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,
