In a sample of students, 12 out of 24 students in a class wanted a sandwich for lunch. Using the data from the sample, predict how many students would want sandwiches for lunch in a school of 400. A 200
B 250
C 300
D 100

200

Step-by-step explanation:

good luck :)

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
