Joan draws a bar chart to show the temperatures at midday
on March 1st in five cities.
Joan has made four mistakes
in her diagram.
Write down any three of them.

Three mistakes in the bar chart drawn by Joan are:

The bar graph of Paris, Munich and Oslo is not properly drawn.

The temperature in y axis does not start with 0

In Munich, the bar graph for x axis is taken more than 1 unit.

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
