A option (c) marginal distribution summarizes the information from one variable ONLY, without considering ANY information from another variable.

A distribution is a mathematical function that shows the likelihood of different values occurring for a given variable.

Now, a marginal distribution summarizes the information from one variable ONLY, without considering ANY information from another variable. It shows the probability of each value occurring for that variable.

In mathematical terms, we can represent a marginal distribution as follows:

P(X = x) = ∑P(X = x, Y = y) for all possible values of y

Here, X is the variable we're interested in, and Y is the other variable that we're not considering. P(X = x) is the probability of X taking on the value x, and P(X = x, Y = y) is the joint probability of X taking on the value x and Y taking on the value y. The summation is taken over all possible values of y.

Therefore, option (c) is correct.

Answer:

12,370.34 square yards

Step-by-step explanation:

The shaded area between the two circles is known as an annulus.

This can be computed by the formula
A₂ - A₁

where
A₁ = area of the inner (smaller circle)
A₂ = area of the outer (larger circle)

We also have
A₁  = π · r₁²
A₂ = π · r₂²

where
r₁ = radius of inner circle
r₂ = radius of outer circle

So

Area of shaded region (area of annulus)
= π · r₂² - π · r₁²
= π (r₂² - r₁²)

We are given r₁ = 25.9 yds

Outer circle has a radius r₂  = inner circle radius + annulus width
r₂ = 25.9 + 42
r₂ = 67.9 yds

Area of the shaded region
= π (67.9² - 25.9²)

= π (4,610.41 - 670.81)

= π  x 3,939.6

=  12,370.344  square yards (using π = 3.14)
=  12,370.34 square yards (rounded to nearest hundredth)

The answer is: A. tan P= 3/4, tan Q=5/4

Trigonometric ratios are mathematical functions that relate the angles of a right triangle to the ratio of the lengths of its sides. There are three primary trigonometric ratios, known as sine, cosine, and tangent, and their reciprocal functions, known as cosecant, secant, and cotangent.

The primary trigonometric ratios are defined as follows:

Sine (sin): The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse of a right triangle.

sin θ = opposite/hypotenuse

Cosine (cos): The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse of a right triangle.

cos θ = adjacent/hypotenuse

Tangent (tan): The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side of a right triangle.

tan θ = opposite/adjacent

The reciprocal trigonometric ratios are defined as follows:

Cosecant (csc): The cosecant of an angle is the reciprocal of the sine of the angle.

csc θ = 1/sin θ

Secant (sec): The secant of an angle is the reciprocal of the cosine of the angle.

sec θ = 1/cos θ

Cotangent (cot): The cotangent of an angle is the reciprocal of the tangent of the angle.

cot θ = 1/tan θ

Trigonometric ratios are widely used in mathematics, science, and engineering to solve problems involving right triangles, as well as to model and analyze periodic phenomena such as sound waves, light waves, and electromagnetic waves.

Since angle R is a right angle, we can use the tangent ratio for angles P and Q as follows:

tan P = RP / RQ = 12 / 16 = 3 / 4

tan Q = PQ / RQ = 20 / 16 = 5 / 4

Answer:

392ft²

Step-by-step explanation:

We need to find out the area of the side walk .The area of the sidewalk will the difference of the areas of rectangles ABCD and EFGH .

The dimensions of rectangle EFGH is 35ft * 14ft

So it's area would be ,

A = l*b

A = 14ft * 35ft

A = 490ft²

Now the length of the rectangle EFGH will be,

l = 35ft + 2*3.5ft

l = 35ft + 7ft

l = 42ft

Again,its breadth will be,

b = 14ft + 2*3.5ft

b = 14ft + 7ft

b = 21ft

So it's area would be,

A = l * b

A = 42ft * 21ft

A = 882ft²

Therefore the area of the sidewalk will be,

ar(sidewalk) = ar(ABCD) - ar(EFGH)

ar(sidewalk) = 882ft² - 490ft2

ar(sidewalk) = 392ft²

and we are done!

The cross section of a cylinder is a circle. This is because a cylinder is formed by two circular bases connected by a curved surface. When the cylinder is sliced perpendicularly to its bases, the cross section will be a circle.

To prove this mathematically, let us consider a cylinder with radius r and height h. The volume of the cylinder is V = πr²h. If the cylinder is sliced perpendicularly to its bases, its cross section can be considered as a circle with radius r. The area of the circle is A = πr². Since the volume of the cylinder is equal to the area of the cross section multiplied by the height, we can say that V = A * h. This implies that A = V/h. Since we already know that V = πr²h, we can substitute the value of V in the above equation to get A = πr²h/h. Cancelling both h from the equation, we get A = πr². This means that the area of the cross section of the cylinder is equal to the area of a circle with radius r. Therefore, the shape of the cross section of the cylinder is a circle.
