Compared to others, which one of the following is not robust to outliers? a) Mean b) Median c) Mode d) 50th percentile

Mathematics

Answer:

The mean.

Step-by-step explanation:

The mean is not robust.

The presence of an outlier greatly affects the value of a mean.

An example will illustrate this.

Find the mean of  the numbers   2  3  5  6  34.

34 is an outlier. The mean = (2+3+5+6+34) / 5 = 10.

Now   if we replace the outlier with a number closer to the others:

Say we have 2 3 5 6 8 :

The mean = (2+3+5+6+8) / 5 =  4.8 which is a much truer measure of centrality than 10.

Hey guys ( or gals ) I have no idea what to do please help me.
shepuryov [24]

Answer:

Irrational numbers cannot be written as a fraction, or the ratio of two whole numbers.

You would have to find a GCF (greatest common factor) and multiply it out of the radical.

ex.

\sqrt{6} = 2 x 2 x 2

when you have to multiplier numbers then you can combine two of them to take outside the radical, meaning 2x2x2

2\sqrt{2\\}

so \sqrt{6} would be closest to the positive 2 on the number line and 2 notches.

\sqrt{11}

is an irrational number, so it might fall into 3.3 if turned into a decimal.

If 588 digits were used to number the pages of a book how many pages are in this book.
iVinArrow [24]

Answer: 232 pages

Step-by-step explanation:

Total digits = 588

1 digit page number:

1 to 9 = 1 × 9 = 9

Number of pages = 9/1 = 9

2 - digit page number :

10 - 99 = 2 × 90 = 180

Number of pages = 180/2 = 90

3 - digit page number :

588 - (9 + 180) = 588 - 189 = 399

Number of pages with 3 - digits = 399/3 = 133

Therefore, the total number of pages the book has is :

(9 + 90 + 133) = 232 pages
