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.

d) 48

step-by-step explanation:

16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,288,304,320,336

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

there is no graph so i cant sorry
