Since the Johnstown Inclined Plane in Pennsylvania is known to be one of the world's longest and steepest hoists. The railway trains traverse 896.5 feet at an inclination of around 35.4 degrees, reaching a height of 1693.5 feet above sea level.

Because the slope's length is 896.54 feet and its inclination is 35.4 degrees, let h be the vertical rise of the incline. Based on trigonometric identities,

Sin 35.4 = h/896.54

h = 896.54 (Sin35.4)

h = 519.35 feet.

Thus, it is right to state that the vertical rise of the included plane is 519.35 ft.

One example of a nonempty subset u of R^2 such that u is closed under scalar multiplication, but u is not a subspace of R^2, is the set u = {(x, y) | x, y are rational numbers}.

This set is closed under scalar multiplication as if a and (x,y) are in u, a*(x,y) will also be in u because rational numbers are closed under multiplication.

A subset can be described with different properties, one of them is closure, a subset U is closed under an operation if the operation is applied to any two elements of U, and the result is also an element of U.

In mathematics, a subset is a set that is completely contained within another set. It is defined as a set U that is a part of a set S, such that every element of U is also an element of S. The notation used to indicate that U is a subset of S is U ⊆ S.

However, this set u is not a subspace of R^2 because it doesn't contain the zero vector (0,0) and it doesn't close under addition, as the sum of two rational numbers may not be a rational number.

Therefore, One example of a nonempty subset u of R^2 such that u is closed under scalar multiplication, but u is not a subspace of R^2, is the set u = {(x, y) | x, y are rational numbers}.

Comparing column a with column b we get that column b is greater than column a. Hence, option B is the correct answer to this question.

Column a: We can find the surface area of a cone by using the formula -

Surface area = π * r * (r + l)

where r is the radius of the base and l is the slant height of the cone.

Substituting r = 3 cm and l = 8 cm, we get,  

Surface area = π * 3 * (3 + 8) = π * 3 * 11 = 33π

Hence, Surface area = 33π  [tex]cm^2[/tex]

Column b: We can find the surface area of a cone by using the formula -

Surface area = π * r * (r + l)

where r is the radius of the base and l is the slant height of the cone.

Substituting r = 4 cm and l = 6 cm, we get,

Surface area = π * 4 * (4 + 6) = π * 4 * 10 = 40π

Hence, Surface area = 40π  [tex]cm^2[/tex]

Comparing we get that,

The surface area of the cone with a base radius of 3 cm and slant height of 8 cm < the surface area of the cone with a base radius of 4 cm and a slant height of 6 cm.

b) The sample is going to be representative.

What is sampling?

Sampling is a technique for choosing certain individuals or a small portion of the population in order to draw conclusions about the population as a whole and estimate its characteristics. Researchers frequently utilise various sampling techniques in market research so they do not have to study the full community in order to gather useful information.

In non-probability sampling, participants are chosen at random by the researcher. This type of sampling is not a set or predetermined selection procedure. This makes it challenging for every component of the population to have an equal chance of being included in a sample.

The sampling method used in non-probability sampling as the people selected are selected on a convenience basis.

A representative sample is a subset of a population that seeks to accurately reflect the characteristics of the larger group.

Since, the students are chosen randomly but from the same room of the same school they might represent the characteristics of all other students.

Therefore, the sample is representative.

a. It is more likely to randomly select square yards of material and finding an average of or more flaws.

b. Normal distribution assumes that the data is continuous and symmetric, but in this case, the number of flaws per square yard is a count data, and it is not symmetric. Therefore, a normal distribution cannot be used to calculate the probability of the first event in part (a).

c. To calculate the probability of the second event in part (a), we would need the mean and standard deviation of the number of flaws per square yard, as well as the specific threshold of "or more flaws" to calculate the area under the curve that is greater than or equal to that threshold. Without that information, I cannot provide an accurate probability calculation.

I determined that it was not possible to calculate the probability of the second event in part (a) without the specific mean and standard deviation of the number of flaws per square yard and the specific threshold of "or more flaws." This is because in order to calculate the probability of an event, you need to know the underlying distribution of the data and the specific cut-off point for the event in question.

In the other part of the question, I stated that it is more likely to randomly select square yards of material and finding an average of or more flaws than it is to randomly select a square yard of material and finding 2 or more flaws.

I came to this conclusion without any calculations because in general, when you are looking for a specific number of flaws (in this case, 2 or more flaws) in a single square yard, it is typically less likely than finding an average of that number of flaws when you look at multiple square yards. This is because the number of flaws per square yard can vary, so even if the average is 2 or more flaws per square yard, it is still possible to find square yards with fewer than 2 flaws.

Using Pythagorean theorem, AD = 9 units and AC = 25 units.

ΔABC is a right triangle.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

Using Pythagorean theorem:

AB² = AD² + BD²

AD = √(AB² - BD²)

AD = √(15² - 12²)

AD = 9 units

AC = AD + CD

AC = 9 + 16 = 25 units

For ΔABC:

The hypotenuse is AC = 25.

Using  Pythagorean theorem to confirm if ΔABC a right triangle. That is:

AC² = BC² + AB²

25² = 20² + 15²

625 = 625

Since the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. Therefore, ΔABC is a right triangle.

Basic division is an arithmetic operation that involves two numbers. It is used to find out how many times one number can be divided into another. It is sometimes referred to as division or division by a divisor.

Division is the inverse operation of multiplication. This means that division is the opposite of multiplication. When a number is multiplied by another number, the result is the product of the two numbers. When a number is divided by another number, the result is the quotient of the two numbers.

The process of division involves finding the number of times that one number can be divided into another. Division is performed by dividing the dividend (the number being divided) by the divisor (the number that divides the dividend). The result of the division is the quotient.

Division can be done using a variety of methods. Long division is a traditional method of division, often taught to students in elementary school. It involves breaking down each number into individual digits and then dividing them one at a time.

Another type of division is short division, which is a simpler and faster method of division that can be done in one step. Short division can be used when the divisor is a single-digit number.

Using microscopic slivers or stripes of the region, a definite integral is a formal estimate of the area beneath a function. Integrals can reflect a region's (signed) area, the total value of a function that changes over time, or the amount of a particular thing given its density.

By performing a definite integral between the two locations, one may determine the area under a curve between two points. Integrate y = f(x) between the limits of a and b to determine the area under the curve y = f(x) between x = a and x = b. Areas below the x-axis will have a negative result, while those above the x-axis will have a positive result.

Correct option is C, The height of triangular prism is not 6 units, it is 15 units.

A triangle base, a translated copy, and three faces that join the appropriate sides make up a triangular prism, a three-sided prism. There are no rectangular sides in an oblique right triangle; it is only a right triangle. A right triangle is a uniform triangular prism, which has square sides and equilateral bases.

In essence, it is a polyhedron with three parallel sides, three surface normals in the same plane, and three surface normals (which is not necessarily parallel to the base planes). These three faces make it a parallelogram. Every cross-section that follows the base faces yields the same triangle.

For the given triangular prism,

The perimeter of base = Side + Side + Side = 13+11+8 = 32 units

The area of base = 1/2 × Base × Height = 1/2 × 11 × 6 = 33 units²
