6. The customer service department of Verizon has determined that the average
customer service call is 9.2 minutes, with a standard deviation of 2.4 minutes. Assume that the call
times are normally distributed.
a) Find the probability that a call will be less than 8 minutes.
a) Find the probability that a call will be more than 7 minutes.
b) Find the probability that a call will be between 8 and 15 minutes.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

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
