Consider data below 20,40,50,50,60,80,80,80 Each value increases by 10

Is the statement true or false

mean increase by 10

Median and mode increase by 10

20,40,50,50,60,80,80,80

For this case we see that the mean is given by:

And replacing we got:

The original median is:

And the mode:

And for this case if our new dataset is this one:

20,40,50,50,60,80,80,160

The new mean would be:

And the median would be:

And we have two values for the mode 50 and 80.

So then the statement is FALSE since we see that if we increase the mean by 10 and the median is the same and not changes and the same for the mode.

Step-by-step explanation:

For this case we have the following dataset :

20,40,50,50,60,80,80,80

For this case we see that the mean is given by:

And replacing we got:

The original median is:

And the mode:

And for this case if our new dataset is this one:

20,40,50,50,60,80,80,160

The new mean would be:

And the median would be:

And we have two values for the mode 50 and 80.

So then the statement is FALSE since we see that if we increase the mean by 10 and the median is the same and not changes and the same for the mode.

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

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
