Answer:55
Step-by-step explanation: since there are basically two medians for the third quadrant, you add them and then divided by 2. 50 and 60 equal 110. 110 divided by two is 55. 55 is your third quadrant
So in a division equation you would take the dividend then divide it by the divisor (which in this case would be the 2) then after you divided you would get your quotient
Since the variance of a Poisson distribution with rate parameter

is

, we know that

. So,
5 lbs. = 80 oz.
80 - 12 = 68 oz.
68 / 4 = 17 bags
