Jake asked students, "How many hours do you sleep each night?" Three students said 7, two students said 8, four students said 9, and 1 student said 10. Describe how he can display the data in a dot plot.

he would make a number line from 7 to 10. and then he would put three dots over 7, two dots over 8, four dots over 9, and one dot over 10.

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
