Find the output, y, when the input x is -7.

Y = -6

Step-by-step explanation:

So the x is -7. So go down the line to the left until you get to -7, which is between -6 and -8. Then go down to where the line is. It hits the line at (-7, -6) so y = -6

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
