The relation R is shown below as a list of ordered
pairs.
R = {(1,4), (1, 3), (-1,3), (2, 15) }
Which ordered pairs prevent this relation from
being a function?
o (1,4) and (1, 3), because they have the same
X-value
(1, 3) and (-1, 3), because they have the
same y-value

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

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
