Hi. i also need with this question as well.

B

Step-by-step explanation:

The diagram shows four points through which the line of proportional relationship should pass. One of these points has coordinates (8,28).

The line representing proportional relationship is always straight line passing through the origin and has the equation

where k is the coefficient of proportionality.

Substitute coordinates of known point into the equation:

so the coefficient of proportionality is equal to

idk

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
