What is a definition of lottery?

A lottery is a low-odds process or game of chance in which winners are chosen at random. Lotteries can be utilized in decision-making circumstances, such as the distribution of scarce medical care and the selection of sports teams.

With a set of numbers, the lottery game is played in finance. Either manually or automatically, the numbers are selected at random. The picked numbers are intended to win prizes. The prize money may be awarded to the winner as a flat sum or in installments. In general, prize winners prefer receiving a lump sum of money.

Managers at eller manufacturing are considering purchasing a new refrigerated delivery truck that will produce equal annual cash flows of $36,000 for 6 years. The truck’s net present value is $12,780, its cost is $144,000, its useful life is 6 years, and its annual depreciation expense (no salvage value) is $24,000. What is the discount rate used by eller to evaluate this project?.

Answers

It should be noted that the discount rate that was used by Eller to evaluate this project is 10%.

From the information given, the following can be depicted:

Annual cash inflows = $36,000 Period of cash inflows = 6 years Cash outlay (initial investment) = $144,000 Depreciation expense = $24,000 Estimated useful of trucks = 6 years Net present value = $12,780

It should be noted that the Present Value Annuity Factor at 10% for 6 years is given as 4.355

Therefore, the Present Value of Annuity cash inflows will be

= ($36,000 x 4.355) =  $156,780  

Less initial investment cash outlay =  $144,000

Net present value =  $12,780

Longitude and Population Density

Explanation:

Longitude

Longitude won't have much effect because it is just across the earth in E to W. (east to west). While, Latitude will affect the Earth because there is something called a Equator, which is USUALLY hot, and the Polar zones, which are mostly Cold.

Population Density

Population Density won't affect much because the amount of carbon dioxide a person produces is pretty less. But yeah, the factories make a lot of more Carbon Dioxide so that is why they will be producing more than the people. But people can't produce so much to warm up their environment.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics?.

Answers

Answer:

The first law describes how thermal energy is conserved but not the direction it moves.

 

Thermodynamics is demonstrated as the branch of physics that deals with the associations or relationships between heat and other energy forms like mechanical, chemical, and electrical).

As per the question, the first law discusses that heat is a kind or form of energy and thus, processes associated with thermodynamics are subject to energy conservation principle. Therefore, heat energy can neither be destroyed nor created but rather transferred to one place to another and converted to and from other energy forms.

Thus, the first law of thermodynamics is distinct from the second law as 'the former describes how thermal energy can be conserved to and from other forms of energy and not the direction in which it moves' while the second law focuses on entropy.

Sunlight changes the distribution of traits in a population because the environment can factor into the distribution of traits.

Sunlight emits light and heat, or solar energy, which allows life to exist on Earth. Sunlight is required for plant growth. Plants are required by animals, including humans, for food and the oxygen they produce.

Earth would freeze if the sun did not provide heat. The sun is necessary for human health and well-being. The health benefits of sunlight include vitamin D production, bone health support, blood pressure reduction, disease prevention, and mental health promotion.

Explanation:

During the 14th century, many parts of Europe and Asia were completely ravaged by an epidemic plague called The Black Death. It was a form of bubonic plague caused by rats infected by bacteria.

More than half of the population of Europe was killed due to his plague, which immediately creates a shortage of labor. Shortage of labor, including agricultural ones, immediately meant that the living ones would receive a higher wage, to the consternation of the landowners who pushes for legislation that would return the status quo to how it was prior to the Black Death. This enrages the peasants who worked for them; manifesting in several revolts from May to November 1380.

But if it was in indirect speech, it must be "asked".Secondly, you haven't given a comma after said. You must give so.Thirdly, the w of where should be in capital. Lastly, you have written the "?" after the double quotes. You should write it before the quotes. So the correct sentence will be:Mrs.Hendrics asked, "Where are the books?"

F(x, y) = e−x + y2, e−y + x2 , c consists of the arc of the curve y = cos(x) from − ???? 2 , 0 to ???? 2 , 0 and the line segment from ???? 2 , 0 to − ???? 2 , 0.

Answers

Given that y = cos(x) makes up part of the boundary of C, I suspect you mean the given points to be (-π/2, 0) and (π/2, 0).

I also assume the given vector field is

[tex]\vec F(x,y) = \left\langle e^{-x} + y^2, e^{-y} + x^2 \right\rangle[/tex]

Since [tex]\vec F[/tex] has no singularities on C or in its interior, Green's theorem applies:

[tex]\displaystyle \int_C \vec F(x,y) \cdot d\vec r = \iiint_D \frac{\partial(e^{-y}+x^2)}{\partial x} - \frac{\partial(e^{-x}+y^2)}{\partial y} \, dA = 2 \iiint_D (x + y) \, dA[/tex]

where D is the interior of C, the region

[tex]D = \left\{ (x, y) : -\dfrac\pi2 \le x \le \dfrac\pi2 \text{ and } 0 \le y \le \cos(x) \right\}[/tex]

The integral then reduces to

[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \int_0^{\cos(x)} (x + y) \, dy \, dx[/tex]

[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac12 \cos^2(x) \right) \, dx[/tex]

[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac{1 + \cos(2x)}4 \right) \, dx[/tex]

[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 4x\cos(x) + 1 + \cos(2x) \right) \, dx[/tex]

Since 4x cos(x) is an odd function over the symmetric interval [-π/2, π/2], its contribution to the integral is 0, and the remaining integral is trivial.

[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 1 + \cos(2x) \right) \, dx = \boxed{\frac\pi2} [/tex]

Yes, sound waves would travel slower at the North Pole than at the equator because the air is denser and is harder to pass through.

What are equators?

The Equator is the midline of the earth.  A vibration results in a sound. We refer to these motions as "sound waves." Sound waves require a specific medium to travel through. The three different types of media are solid, liquid, and gas.

Keep in mind that since a "solid medium" is denser than the other two, sound waves move through it more quickly. Because water is more densely packed with particles than gas is, sound waves travel faster in liquid than in gas (such as air).

Therefore, yes, because the air is heavier and more difficult to get through at the North Pole than it is at the Equator, sound waves would move more slowly there.
