a survey was taken of children between the ages of 3 and 7. let a be the event that the person has 2 siblings, and let b be the event that the person does not have a pet.

which statement is true about whether a and b are independent events?

a) a and b are independent events because p(a∣b) = p(a) = 0.18.
b) a and b are independent events because p(a∣b) = p(a) = 0.4.
c) a and b are not independent events because p(a∣b) = 0.4 and p(a) = 0.18.
d) a and b are not independent events because p(a∣b) = 0.18 and p(a) = 0.4.

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,
