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.

In finance the notion of expected value is used to analyze investments for which the investor has an estimate of the chances ass
blagie [28]

Answer:

Step-by-step explanation:

The expected return is given as

Expected Return = SUM (Return i x Probability i). i=1,2,3.....

First investment

Probability of 0.7, it returns 60cents per dollars

Second investment

Probably of 0.3, it loses 20cents per dollar.

Expected return=(0.7×60)-(0.3×20)

Excepted return= 42-6

Excepted return=36cents

To dollars, 1cents is 0.01dollars

Then, 36cents = 0.36dollars

Expected return=$0.36

The base of a triangle is 2ft The height of the triangle is 15 in what is the area of the triangle in square inches
Yakvenalex [24]

Answer:

Area of a triangle = A = 180in^{2}

Step-by-step explanation:

Given Data:  

height of a triangle = h = 15 in

base of a triangle = b = 2 feet  = 2*12 =24 in

To Find Out:  

Area of a triangle = A = ?  

Formula:  

Area of a triangle = A =  \frac{1}{2} (b*h)

Solution:  

Area of a triangle = A =  \frac{1}{2} (b*h)

Area of a triangle  = A =  \frac{1}{2} (24*15)

Area of a triangle  = A =  \frac{1}{2} (360)

Area of a triangle = A = 180in^{2}
