When the outliers are removed, how does the mean change?

jok3333 [9.3K]

In statistics, an outlier is an observation point that is distant from other observations.

Given the points
15, 23, 24, 26, 27 and 35

Notice, that the points 15 and 35 are distance from the other points and hence are outliers.

The mean of the observations including the outliers is given by
$\frac{15+23+24+26+27+35}{6} = \frac{150}{6} =25$

The mean of the observations without the outliers is given by
$\frac{23+24+26+27}{4} = \frac{100}{4} =25$

Therefore, when the outliers are removed, the mean remains the same.

29. Martin has some dollar notes. 20% of the notes are $10 notes, 40% of

Katena32 [7]

Answer:

225 notes

Step-by-step explanation:

Let the number of notes is x.

20% of notes is:

0.2x

40% of the remainder is:

40% of 0.8x, so it is
0.8x*0.4 =
0.32x

Remaining notes are:

x - 0.2x - 0.32x =
0.48x

Total of the notes:

0.2x*10 + 0.32x*5 + 0.48x*2 = 1026
2x + 1.6x + 0.96x = 1026
4.56x = 1026
x = 1026/4.56
x = 225

What is the difference between multiplying monomials and adding/subtracting monomials?

mario62 [17]

EX. 3x+3x. You will leave the variable alone. You add the constants (3 and 3). The answer is 6. Because of that x, the answer is 6x.

EX. 3x times 3x. Again you will leave the x alone. You multiply the constants (3 and 3). The answer is 9. Because of the x, the answer is 9x.
