A group of 7 students was asked, “How many hours did you watch television last week?” Here are their responses.

9, 4, 14, 13, 12, 17, 13

Find the mean number of hours for these students. If necessary, round your answer to the nearest tenth.

11.7

Step-by-step explanation:

To find the mean, you need to add up all the responses and then divide by the number of responses there are. So we would do 9 + 4 + 14 + 13 + 12 + 17 + 13. You get 82 when adding all of this up and because there are 7 responses we would divide. 82 ÷ 7 = 11.7142857. Since you are rounding to the tenth, you  get 11.7

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

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
