George is an artist and wants to showcase his work in an exhibition.


George requires 30 hours to make a sculpture and 15 hours to make a painting. To display at the showcase he needs at least 5 sculptures and 6 paintings to be ready.


Let x represent the number of sculptures, and let y represent the number of paintings. If George has 300 hours left before the exhibition, which inequalities represent the constraints on the number of sculptures and paintings he can display?


1. x is less than or equal to 5
2. 30x+15y is less than or equal to 300
3. x is greater than or equal to 5
4. y is greater than or equal to 6
5. 15x+30y is greater than or equal to 300
6. y is less than or equal to 6

Answer:

x = 3 or x = -1/2

Step-by-step explanation:

Solve for x:

2 x^2 - 5 x - 3 = 0

The left hand side factors into a product with two terms:

(x - 3) (2 x + 1) = 0

Split into two equations:

x - 3 = 0 or 2 x + 1 = 0

Add 3 to both sides:

x = 3 or 2 x + 1 = 0

Subtract 1 from both sides:

x = 3 or 2 x = -1

Divide both sides by 2:

Answer: x = 3 or x = -1/2

Using the provided percentages, it is discovered that:

a) A randomly chosen dorm room has a 31% chance of having a TV but no refrigerator.

b) A randomly chosen dorm room has a 48% chance of having either a television or a refrigerator, but not both.

c) There is a 31% chance that a randomly chosen dorm room lacks both a refrigerator and a television.

Item a:

TVs were owned by 52% of people.

21% of them had a refrigerator as well.

52 - 21 = 31

A randomly chosen dorm room has a 31% chance of having a TV but no refrigerator.

Item b:

31% just have a TV.

Only 17% of people—38—have a refrigerator.

31 + 17 = 48

A randomly chosen dorm room has a 48% chance of having either a television or a refrigerator, but not both.

Item c:

The likelihood that at least one exists is:

P(A∪B) = P(A) + P(B) - P(A∩B)

Hence:

P(A∪B) = 0.52 + 0.38 - 21 = 0.69.

Answer:

The probability that a randomly selected dorm room has a TV but no refrigerator is 0.31

What is Probability?

Probability is a branch of mathematics that quantifies the likelihood of an event occurring or the likelihood of a statement being true. The probability of an event is a number between 0 and 1, with approximately 0 indicating the improbability of the event and 1 indicating certainty.

According to question

The probability that a randomly selected dorm room has a TV but no refrigerator

Solution :

Suppose

A = event of having refrigerators,

B = event of having a TV,

We have,

P(A) = 34% = 0.34,

P(B) = 51% = 0.51,

P(A∩B) = 21% = 0.21

Therefore:

Probability of a TV but no refrigerator = P(A∩B')

= P(A) - P(A∩B)

= 0.34 - 0.21

= 0.31

43920  is the lowest amount that a teacher needs to make and still be one of the top 7% earners with a mean of $38,000 and a standard deviation of $4,000

According to information provided to us, the pay for elementary school teachers in a certain nation is generally distributed, with a mean of $38,000 and a standard deviation of $4,000 per year.

To resolve the issue at hand, we shall make use of the normal distribution table. Finding the z-score corresponding to the top 7% or the 93% probability from the normal distribution table (0.93).

The normal distribution table provides us with the 1.48 z-score we need.

We will now solve for the sample score using the z-score formula as follows:

z = x - μ/σ

1.48 = x - 38,000/4000

1.48 × 4000 = x - 38,000

The hot air balloon travels 40 miles against the wind in the same amount of time that it travels 200 miles with the wind. Therefore, the rate of the hot air balloon against the wind is 40 miles/200 miles x 20 mph = 8 mph.

1. Calculate the ratio of the distance traveled against the wind compared to the distance traveled with the wind: 40 miles/200 miles = 0.2

2. Multiply the ratio by the speed of the wind: 0.2 x 20 mph = 4 mph

3. The speed of the hot air balloon against the wind is 8 mph.

The hot air balloon is able to travel at a speed of 20 mph when the wind is in its favor. However, when the wind is not in its favor, the hot air balloon must travel against the wind, drastically decreasing its speed. In the same amount of time, the hot air balloon was able to travel 40 miles against the wind while it was able to travel 200 miles with the wind. To calculate the speed of the hot air balloon against the wind, we can use the following formula: Speed = (Distance against the wind/Distance with the wind) x Speed of the wind. In this case, the ratio of the distance traveled against the wind compared to the distance traveled with the wind is 40 miles/200 miles = 0.2. When we multiply this ratio by the speed of the wind, which is 20 mph, we get 4 mph. Therefore, the rate of the hot air balloon against the wind is 8 mph.

Generally speaking, a S corporation is put up to reduce the tax obligations. It is Option (3).

A business form known as a S corporation is one that is allowed by the tax code to distribute its taxable income, credits, deductions, and losses to its shareholders directly. This provides it certain advantages over the more popular C corp. The S corp, an alternative to the limited liability company, is only available to small firms with 100 or fewer stockholders (LLC). S corporations and LLCs are both referred to as "pass-through entities" since they don't pay corporate taxes, instead, they pay their owners, who are then in charge of paying the necessary taxes.

One sort of legal corporate structure that is popular among small businesses is the S corporation, commonly referred to as a S corp or S corp or S subchapter. Another is a limited liability company (LLC). A corporation with 100 shareholders or fewer can profit from incorporation while still being taxed as a partnership thanks to the requirements of a S corp. S corporations and LLCs are both pass-through companies, which means they don't pay corporate taxes and provide their owners and principals with limited liability protection. LLCs, however, offer more flexibility.

In arithmetic, a function from a group X to a group Y assigns to every part of X precisely one part of Y. The set X is termed the domain of the function and therefore the set Y is termed the codomain of the function

Main body:

A parametric curve is a function expressed in components form, such that

x=f(t) , y=g(t). The length of a parametric curve on the interval a ≤ t ≤ b is given by the definite integral :

L =  [tex]\int\limits^a_b {\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt} )^2} } \, dt[/tex]

Let's begin by getting the first derivative of the components of the function with respect to the variable t.

x = e^t - t  

dx / dt = e^t−1

y = 4 e^t/2

dy /dt = 2 e^t/2

Substitute the derivatives into the following definite integral which computes the length of the parametric curve on the interval

[a,b]=[0,2].

L =[tex]\int\limits^a_b {\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt} )^2} } \, dt[/tex]

L=  [tex]\int\limits^2_0 {\sqrt{(e^{t}-1 )^2 + (2e^{t/2} } )^2} } \, dt[/tex]

L =[tex]\int\limits^2_0 {e^{t} -1} \, dt[/tex]

Evaluate the solution at the limits of integration to get the length.

L = (e² - 1 )- (e⁰ - 1)

Answer:

The Pacific Ocean is approximately 4.9 times larger than Lake Superior in terms of volume. This can be shown through the following mathematical argument:

First, divide the volume of the Pacific Ocean by the volume of Lake Superior to determine the size ratio:

6 x 10^8 cubic kilometers / 1.22 x 10^4 cubic kilometers = 4.9

This shows that the Pacific Ocean is approximately 4.9 times larger than Lake Superior.

To defend this solution, we can use the concept of ratio and proportion. We know that the ratio of the volumes of the two bodies of water is equal to the ratio of their respective sizes. Therefore, by finding the ratio of the volumes, we can determine the size ratio.

In this case, the ratio of the volumes is 6 x 10^8 cubic kilometers / 1.22 x 10^4 cubic kilometers, which simplifies to 4.9. This means that the Pacific Ocean is 4.9 times larger than Lake Superior in terms of volume.

This solution can be further supported by the fact that the Pacific Ocean is the largest ocean in the world, while Lake Superior is one of the Great Lakes and is much smaller in size.

The value of (1 + i)^5 is -2 * 2^1.5 * (1 + i). De Moivre's describes how the power of a complex number can be calculated using the properties of its modulus and argument.

De Moivre's theorem states that for any complex number z and any integer n, we have (z^n) = (r^n)(cos(nθ) + i * sin(nθ)), where r is the magnitude of z and θ is the angle that z makes with the positive real axis in the complex plane. Using this theorem, we can easily find the fifth power of 1+i as follows:

First, we need to express 1+i in polar form, which is given by z = r * cis(θ), where r is the magnitude of z and cis(θ) is the complex number with magnitude 1 and angle θ in the complex plane. In this case, we have z = 1+i = sqrt(2) * cis(π/4), where sqrt(2) is the magnitude of 1+i and cis(π/4) is the complex number with magnitude 1 and angle π/4 in the complex plane.

Next, we substitute this expression for z into the formula for (z^n) given by De Moivre's theorem, which gives us

(1 + i)^5 = √2^5 * (cos(5 * 45) + i * sin(5 * 45))

        = 2^2.5 * (cos(225) + i * sin(225))

(1 + i)^5 = 2^2.5 * (-cos(45) + i * -sin(45))

        = 2^2.5 * (-1 + i * -1)

        = -2 * 2^1.5 * (1 + i)
