Please tell me the outlier of each set of numbers (3 sets only)!
yulyashka [42]

Hey there!

An outlier in a data set is a number that is WAY larger or WAY smaller than the others in the data set, or does not really fit in the specified "range". In the first one, 452 is way greater than everything else, so it would be the outlier.

In the second data set, 5 would be our outlier because it is much smaller than all the other numbers.

In the last data set, the numbers are pretty close together, but we need to find one that isn't inside the small range. 0.201 appears to be the outlier in this case.

Therefore, here are your answers :)

15: 452

16: 5

17: 0.201

I hope this helps!

OlgaM077 [116]

Answer:

48% of people do NOT like walking

Step-by-step explanation:

First, write it as a fraction 13/25 (People who like jogging)

We want to find out the number of people who DON'T like walking, so we subtract 25-13=12. Put 12/25.

Lastly, convert into a percentage. Percent is out of 100, so we need to make the fraction out of 100. To do this multiply the numerator and the denominator by 4. 48/100.

=

48%

Hope this helps,
