Suppose that the average and standard deviation of the shelf life in years for certain kinds of batteries are 14.79 and 2.67, respectively. Calculate an interval that is symmetric around the mean such that it contains approximately 68% of battery shelf lives. Assume that the life has a normal distribution.1) (17.46, 12.12)2) (20.13, 9.45)3) (12.12, 17.46)4) (14.79, 2.67)5) (9.45, 20.13)

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
