The length and the width of the fencing are 85 feet and 30 feet respectively.

The whole distance that a rectangle's borders, or its sides, the cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the total of its four sides.

Given:

Darrin is hanging 200 feet of Christmas garland on the three sides of fencing that encloses his rectangular front yard.

The length is five feet less than three times the width.

Let w be the width.

Then, 3w - 5 is the length.

So, the perimeter of the rectangular fence = 200 + w.

Now, 2(3w - 5 + w) = 200 + w

6w - 10 + 2w = 200 + w

7w = 210

w = 30

Then length = 85

Therefore, length = 85 feet and width = 30 feet.

On solving the provided question, we can say that the area of the rectangle  polygon is 474 ft².

A rectangle in Euclidean geometry is a parallelogram with four slight angle. It may alternatively be described as a hexagon that is basic rule, or one in which all of the angles are equal. A straight angle is another another option for the parallelogram. In a square, four of the vertices are the same length. A quadrilateral with a rectangle-shaped cross section has four 90 ° angle vertices + equal parallel sides. As a result, it is sometimes referred to as a "equirectangular rectangle". Due to such equal and parallel dimensions of its two sides, a rectangle is occasionally referred to as parallelogram.

The left rectangle has a height of 18 ft and a width of 21 ft, so its area is:

[tex]18 ft x 21 ft = 378[/tex] ft²

The right rectangle has a height of 12 ft and a width of 8 ft, so its area is:

[tex]12 ft x 8 ft = 96[/tex] ft²

Therefore, the total area of the polygon is:

378 ft² + 96 ft² = 474 ft²

So the area of the polygon is 474 ft².

The measure of both the angles is equal and it is of 105 degrees.

Vertical Angles:

The opposing angles created when two lines cross one another. They are always equal.

The vertex, not up or down, where they meet, is the term understood by the phrase "vertical."

In the given question,

m/1 = 3x+21

m/2 = 5x-35

it is also given that, both angles are vertical angles,

therefore,

m/1 = m/2

3x + 21 = 5x - 35

2x = 56

x = 28

Now, place the value of x in given angles,

m/1 = 3 (28) + 21

m/1 = 84 + 21

m/1 = 105

Similarly,

m/2 = 5 (28) - 35

m/2 = 140 - 35

m/2 = 105

Therefore, both the given angles are of 105 degrees.

Answer:-2 °F

Step-by-step explanation:

Este numero es mas frio porque es de menos valor y lo mas bajo que es el numero lo mas frio que se siente.

The second object is approximately 4.4 * 10^9 times bigger than the first object.

The division of the value of the second scientific notation from the first scientific notation is the precise and accurate way with which we can determine many many times bigger is the second object compared to the first object.

To do so, group coefficients together and exponents together to divide numbers in scientific notation. i.e.

= (3.7/8.5) * ((10^6)/(10^−4))

= 0.43529411 ×  ((10^6)/(10^−4))

Subtract the exponent from the denominator from the exponent of the numerator for the same base 0.43529411 ⋅ 10^(6 −4*−1)

= 0.43529411 × ((10^6+4)

= 0.43529411 × 10^10

To find the asymptotic complexity of a function, you need to analyze the behavior of the function as the size of the input grows. You need to determine the number of operations that are performed by the algorithm, and express this as a function of the size of the input.

Asymptotic complexity is a measure of the growth rate of the running time of an algorithm as the size of the input grows towards infinity. It is expressed using big O notation, which provides an upper bound on the growth rate of the running time.

The two equations for f(x) are not equal at x = 1 and f(x) is therefore discontinuous at this point

f(x) is discontinuous at x = 1 because when x = 1, the two separate equations for f(x) do not have the same output. For x < 1, [tex]f(x) = x^2 + 4[/tex], so when x = 1, [tex]f(1) = 1^2 + 4 = 5. For x > 1, f(x) = x + 4[/tex] , so when x = 1, f(1) = 1 + 4 = 5. The output of f(1) is different on each side of the discontinuity. This can be seen in the following calculation:

For x < 1,

[tex]f(x) = x^2 + 4f(1) = 1^2 + 4 = 5For x > 1,f(x) = x + 4f(1) = 1 + 4 = 5[/tex]

Since f(1) is 5 for x < 1 and f(1) is also 5 for x > 1, the two equations for f(x) are not equal at x = 1 and f(x) is therefore discontinuous at this point.

3 and 5 supplementary angles can prove that lines L and M are parallel. The solution has been obtained by using the properties of parallel lines.

What are parallel lines?

In a plane, lines that are parallel to one another do not meet or overlap at any point. They are always parallel and equally spaced apart. Parallel lines are non-intersecting lines. Infinity is another place where parallel lines are believed to meet.

We are given a set of parallel lines and various angles are marked on the lines.

Angles 3 and 4 can not prove that the lines are parallel because they lie on the same line.

Similarly, angles 7 and 8 can also not prove.

Answer:

P(AA) = 0.41

P(PM) = 0.38

P(AA and PM) = 0.05

As you are finding P(AA or PM), you can apply the formula:

P(A U B) = P(A) + P(B) - P( A ∩ B)

U = Union  P( A U B) = P (A or B)

∩ = And

From the formula, you can find out the answer:

P(AA or PM) = P(AA) + P(PM) - P(AA and PM)

(c) P(D or E) is equal to 0.32.

(d) D and E are not independent.

(e) D and E are not mutually exclusive.

The solution has been obtained using probability.

What is probability?

Probability is a mathematical concept used to determine the likelihood of an event. It merely allows us to calculate the probability or possibility that an event will occur. The range of probabilities lies between 0 and 1, where 1 signifies a certain event and 0 denotes an impossibility.

We are given the following:

No. of students that have taken a distance learning class = 8%

No. of students that are part-time students = 30%

No. of part-time students that have taken a distance learning class = 20%

Let D = event that a student takes a distance learning class and E = event that a student is a part-time student.

(a) Since, 20% of the part times students are taking distance learning classes (D and E) so,

P(D and E) = 0.3 * 0.2 = 0.06

(b) P (E | D) = P (D and E) / P (D)

P (E | D) = 0.06 / 0.08

P (E | D) = 0.75

(c) P (D or E) = 0.3 + 0.08 - 0.06 = 0.32

(d) For events to be independent, probability of D and E must be equal to P(D) x P(E).

But, P(D and E) ≠ P(D) x P(E)

So, D and E are not independent.

(e) Events are considered mutually exclusive if they do not occur at the same time.

But, D and E can occur at the same time.

So, D and E are not mutually exclusive.

Step-by-step explanation:

they are forming a right angle (90°).

A uniform random variable's density function is f(y) = 1 for y 1 and 0 otherwise. F(y) = 0 for y 0, F(y) = y for 0 y 1, and F(y) = 1 for y > 1 define the distribution function.

A uniform random variable's density function is f(y) = 1 for y 1 and 0 otherwise. Accordingly, the likelihood of any specific outcome of y is the same, and the likelihood of any range of outcomes is equal to the length of the range. F(y) = 0 for y 0, F(y) = y for 0 y 1, and F(y) = 1 for y > 1 define the distribution function. Accordingly, the length of the range multiplied by the likelihood of any specific occurrence yields the cumulative probability of any range of outcomes. Since the likelihood of any specific result in that range is 1 and the range's length is 0.5, for instance, the cumulative probability of 0 y 0.5 is 0.5. Since the likelihood of any given result within that range is still 1, but the range's length is 0.5, the cumulative probability of 0.5 y 1 is 0.75. The chance of any range of outcomes for y1 and y2 if they are independent random variables both having the uniform(0,1) distribution is just the sum of their respective cumulative probabilities.

Simultaneous equations, Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

Given, Cx = 2x-15 and CE=2x-8 these are the measurement of the distance Of points E and x from the point c

Distance between two points is the length of the line segment that connects the two points in a plane.
