The answer to your question is 424
Answer:
And the deviation would be:
Step-by-step explanation:
For this case we have the following distribution given:
X 0 1 2 3 4 5 6
P(X) 0.3 0.25 0.2 0.12 0.07 0.04 0.02
For this case we need to find first the expected value given by:
And replacing we got:
Now we can find the second moment given by:
And replacing we got:
And the variance would be given by:
And the deviation would be:
Answer:
24 boxes of books
Step-by-step explanation:
maximum capicity - weight of delivery person
1670lb - 180lb = 1490lb
Then divide this by the weight of one box to find out how many total boxes can be taken at once
1490lb ÷ 60lb = 24.8333...
round to 24 as you cannot take 0.8 of a box.
Hope this helped
