Waiting times (in minutes) of customers at a bank where all customers enter a single waiting line and a bank where customers wait in in three different teller windows are listed below. Find the coefficient of variation for each of the two sets of data, then compare the variation
Bank A (single line): 6.4 6.7 6.8 6.8 71 72 7.4 77 77 78 0
Bank B (individual 42 53 5.9 62 66 77 78 8.5 9 2 9.7
The coefficient of variation for the waiting times at Bank A is %
(Round to one decimal place as needed.)

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

i believe the correct answer is b.
