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

ociated with various returns (and losses). For example, suppose you have the following information about one of your investments: With a probability of 0.7, the investment will return 60 cents for every dollar you invest, and with a probability of 0.3, the investment will lose 20 cents for every dollar you invest. The expected rate of return for this investment is calculated the way we calculate the expected value of a game: Multiply the probability of each outcome by the amount you earn (or by minus the amount if you lose) and add up these numbers.

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

In a right triangle, the acute angles measure x + 15 and 2x degrees. What is the measure of the smallest angle of the triangle?
satela [25.4K]

Answer : C. 40

In a right triangle, the acute angles measure x + 15 and 2x degrees

We know right angle is 90 degree.

In right angle triangle , one angle is 90 and other two angles are x+15  and 2x

WE know sum of angles in a triangle = 180

90 + x+15 + 2x = 180 (combine like terms)

105 + 3x = 180

Subtract 105 on both sides

3x = 75 (Divide by 3 on both sides)

x= 25

In right angle triangle , one angle is 90 and other two angles are x+15  and 2x

Replace x with 25

So angles of the right triangle are 40, 50 , 90 degrees

Smallest angle of the triangle= 40

Are Functions 1 and 2 the same? Explain. Function 1: y = 3(x + 5) Function 2: y equals three times x, plus 5.
Molodets [167]

Answer:

No, the functions are not the same.

Step-by-step explanation:

For function one you have to distribute the three to the x and the five which would give you a function of 3x+15.

This will result in different y-intercepts function one's why being 15 and function's two y-intercept being 5. Though the will have the same slope they are two different functions.

Quadrilateral LMNO has diagonals that intersect at point P. If LP=NP, MP = y + 25, and OP = 5y + 29, find the length of MO such
cupoosta [38]
I saw the image of this problem.

For the quadrilateral to be parallelogram, MP = PO

MP = y + 25
PO = 5y + 29

y + 25 = 5y + 29
y - 5y = 29 - 25
-4y = 4
y = 4/-4
y = -1

MO = MP + OP
MO = y + 25 + 5y + 29
MO = -1 + 25 + 5(-1) + 29
MO = -1 + 25 - 5 + 29
MO = -6 + 54
MO = 48  Choice B.

a new rectangular park is planned.it will be 3/4 kilometer long and have an area of 3/8 square kilometers. how many kilometers w
kakasveta [241]

<em>The word usage in last sentence of the question is not well presented. However, I can understand that you intend to solve for the width of the park</em>

Answer:

Width = 2\ km

Step-by-step explanation:

Given

Length = \frac{3}{8}km

Area = \frac{3}{4}km^2

Required

Determine the Width

For a rectangle:

Area = Length * Width

Substitute for Area and Length

\frac{3}{4} = \frac{3}{8} * Width

Multiply both sides by \frac{8}{3}

\frac{8}{3} * \frac{3}{4} = \frac{3}{8} * \frac{8}{3}* Width

\frac{8}{3} * \frac{3}{4} =  Width

\frac{24}{12} = Width

2 = Width

Width = 2\ km
