Ricardo has 3 rolls of tape. Each roll has 8 and 1 third feet of tape. It takes 2 and 2 thirds feet of tape to close a box completely. What is the total number of boxes that Ricardo can completely close using these 3 rolls of tape?

9 boxes

Step-by-step explanation: multiplying the 8 and one third by the number of tape rolls gets you 25, then divide that by 2 2/3 to get an answer of 9.375, and because you cant colse the box with the extra .375, you have to round down, getting you to your answer of 9.  

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
