If the sample size is much smaller than the population size, say 20 times smaller, then random sampling with
replacement and random sampling without replacement are nearly equivalent.

if the probability is 1/12, 75 people will receive a $25 gift card

step-by-step explanation:

80

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
