Due to the ladder's 13-foot height, its angle with the ground is approximately 55.1 degrees.

what is angle ?

The vertex of the angle, which is created by the intersection of two rays, is a geometric figure known as an angle. The sides or legs of the angle are often used terms to describe the rays. Angles can be acute (less than 90 degrees), right (exactly 90 degrees), obtuse (more than 90 degrees but less than 180 degrees), straight (exactly 180 degrees), or reflex. Angles are measured in units of degrees or radians (greater than 180 degrees but less than 360 degrees).

given

In order to solve this puzzle, we must determine the angle that the ladder creates with the ground using the neighbouring side and hypotenuse of a right triangle. The trigonometric function cosine can be used to calculate the angle.

adjacent/hypotenuse = cos

cos θ = 7/13

θ = cos⁻¹(7/13) (using the inverse cosine of both sides) (taking the inverse cosine of both sides)

Calculating the answer, we obtain:

θ ≈ 55.1°

The length of each of the two congruent sides of an isosceles triangle is 2x + 3. The length of the third side is 2x. Its perimeter is 36 centimeters.


Write an equation that could be used to find the value of x.


Solve for x.


Then, find the length of all three sides.

Answers

Answer:

[tex]\huge\boxed{\sf x = 5}[/tex]

Step-by-step explanation:

In an isosceles triangle,

Each of two equal sides = 2x + 3

Third side = 2x

Perimeter = 36

We know that,

Perimeter = Sum of all sides

So,

36 = 2x + 3 + 2x + 3 + 2x

Combine like terms

36 = 2x + 2x + 2x + 3 + 3

36 = 6x + 6Subtract 6 from both sides

36 - 6 = 6x

30 = 6x

Divide both sides by 6

30/6 = x

5 = x

OR

x = 5

Now,

The length of all three sides:

Side 1 and 2:

= 2x + 3

= 2(5) + 3

= 10 + 3

= 13

Side 3:

= 2x

= 2(5)

= 10

Explain how the sample size of an experiment affects the probabilities in a probability model. Be sure to discuss these probabilities in terms of them being realistic estimates of the probability of an event.​

Answers

Answer:

The sample size of an experiment can have a significant impact on the probabilities in a probability model. A larger sample size generally produces more accurate estimates of the probabilities of an event. This is because a larger sample size provides more data points that can be used to calculate the probabilities, which reduces the likelihood of random variation skewing the results.

For example, if you are conducting a coin toss experiment and flip a coin 10 times, the probability of getting heads may not be exactly 50%. However, if you flip the coin 1,000 times, the probability of getting heads will be much closer to 50% because the larger sample size reduces the impact of random variation.

Therefore, a larger sample size can lead to more realistic estimates of the probability of an event because it reduces the impact of random variation and provides more data points for analysis. However, it is also important to note that sample size alone does not guarantee accurate estimates of probability, and other factors such as selection bias and the quality of the experimental design can also affect the accuracy of the results.

The equation of the model given written in point slope form is :

y - 9 = 0.4(x - 14.5)Velocity on meter per second = 0.4 m/sInitial elevation = 3.2 m

What is the equation of the model in slope form?

Final elevation = 50 m

From given information given :

9 meter = 14.5 seconds - - - - (1)

20 meter = 42 seconds - - - - (2)

(20 - 9)meters = (42 - 14.5) seconds

11 meters = 27.5 seconds

The formula for speed is: Distance / time = 11 / 27.5 = 0.4 meters per second

The equation in point slope form can be represented thus:

The initial velocity :

At y = 9 meters ; x = 14.5 seconds ; c = initial elevation

y = 0.4x + c

9 = 0.4(14.5) + c

9 = 5.8 + c

c = 9 - 5.8

c = 3.2 m

So, the in point - slope form, the equation can be written as :Y - 9 = 0.4(x - 14.5) while the initial elevation is 3.2 m.

A random sample of size 100 is taken from a population described by the proportion p = 0.60.
The probability that the sample proportion is between 0.55 and 0.62 is ______.

Answers

The probability that the sample proportion is between 0.55 and 0.62 is 0.7962.

What is Probability?

Probability is the measure of how likely an event is to occur out of the total number of possible outcomes. It is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. Probability is used to describe random events, such as the toss of a coin or the role of a die, as well as more complex events, such as the weather, stock market performance, and the success of a political candidate. A probability of 0.5, for example, means that there is a 50% chance that the event will occur.

This is calculated using the binomial probability formula, which is the probability of a certain outcome of a series of independent binary events. According to the formula, the probability of the sample proportion being between 0.55 and 0.62 is the sum of the individual binomial probabilities for each outcome within the range of 0.55 and 0.62. This is calculated as the sum of the binomial probabilities for each outcome (where p = 0.60): P(x=55) + P(x=56) + P(x=57) + P(x=58) + P(x=59) + P(x=60) + P(x=61) + P(x=62). The result is 0.7962.

You want the index of the pixel at (x, y) = (15, 22) in a 128×128 array, if the pixel at (0, 0) has index 0, and the pixel at (0, 1) has index 128.

Index

The index increase by 128 for each additional row (y-value), so the index of pixel (x, y) is ...

  i = x +128y

The index for pixel (15, 22) is ...

  i = 15 +128·22 = 15 +2816

B) $187,205
C) $282,799
D) $470,004

Answers

The net worth of the landscaping company is given by:

$187.205.

How to calculate the net worth?

The net worth of a company or of a person is given by the sum of all assets of the person subtracted by the sum of all debts of the person.

In the context of this problem, the assets, and it's values, of the company are given as follows:

Owned Inventory: $48,760.

Cash: $126,790.

Savings account: $32,436.

Owned equipment: $20,700.

Accounts receivable: $15,640.

Property value: $225,678.

Hence the sum of the assets is given by:

Assets = 48760 + 126790 + 32426 + 20700 + 15640 + 225678 = $469,994.

The debts of the company, with it's values, are given as follows:

Small Business Loan: $76,400.

Building Mortgage: $189,429.

Other debt: $16,970.

Hence the sum of the debts is given by:

Debts = 76400 + 189429 + 16970 = $282,799.

Then the net worth of the company is:

Net worth = Assets - Debt = 469,994 - 282,799 = $187,205.

What is equation?

An algebraic equation is a method of connecting two quotes by using the equals symbol (=) to express equality. In algebra, an explanation is a definitive expression that verifies the equivalency of two formula. For example, the identical character divides the numbers 3x + 5 and 14. A linear equation might be used to recognize the connection that existing between the texts written on separate sides of a letter. The product and application both frequently the same. 2x - 4 equals 2, for example.

We can factor out x to get the answer to the equation Ax2 - 3x = 0.

x(Ax - 3) = 0

We can set each factor to zero and solve for x because the product of two factors is zero if and only if one or both of the factors are zero.

x = 0 or Ax - 3 = 0

If A is greater than zero, we can solve the second equation for x by adding 3 to both sides and dividing by A:

[tex]Ax-3 = 0 Ax-3 = 3 x = 3/A[/tex]

Equation: What is it?

The equals sign (=), which expresses equality, is a way to join two quotes in an algebraic equation. An explanation in algebra is a conclusive phrase that confirms the similarity of two formulas. The same letter, for instance, divides the integers 3x + 5 and 14.

The relationship between the texts written on the different sides of a letter can be determined using a linear equation. Products and applications are usually interchangeable. In this case, 2x - 4 equals 2.

From the question,

We can factor out x to get the answer to the equation ax² - 3x = 0.

x (ax - 3) = 0

The product of two factors is zero if and only if one or both of the factors are zero, thus we can set each element to zero and find x.

x = 0 or ax - 3 = 0

By adding 3 to both sides and dividing by a, we may solve the second equation for x if a is greater zero:

ax = 3

⇒ x = 3/a

Therefore, the solutions of the equation are x = 0 and x = 3/a.

The measure of missing angles are ∠3 = 25°, ∠4 = 25°, ∠1 = 133°, ∠2 = 94°, ∠5 = 43° and ∠6 = 43°

What are angles?

A pοint where twο lines meet prοduces an angle.

The breadth οf the "οpening" between these twο rays is referred tο as a "angle". It is depicted by the figure.

Radians, a unit οf circularity οr rοtatiοn, and degrees are twο cοmmοn units used tο describe angles.

By cοnnecting twο rays at their ends, οne can make an angle in geοmetry. The sides οr limbs οf the angle are what are meant by these rays.

The limbs and the vertex are the twο main parts οf an angle.

We can see that

∠3 = ∠4                               ⇒ CPCT, As ΔDBA ≅ ΔDBC, SAS theorem

∠5 = ∠6                              ⇒ Isosceles triangle, thus two angles are equal

∠1 + ∠2 + 133 = 360°          ⇒ angle sum theorem

Now,

∠3 = 180 - 133 + 22

∠3 = 25°

also,

∠4 = 25°

Now,

∠1 = 133°     ⇒  CPCT

∠2 = 360 - (133 + 133)

∠2 = 94°

Now, ∠5  =  ∠6

As 180 - ∠2 = ∠5 + ∠6

180 - 94 = ∠5 + ∠6

180 - 94 = ∠5 + ∠6

86 = ∠5 + ∠6

∠5 = 86/2

∠5 = 86/2

What are parallel lines?

When two lines in a plane do not cross at any point, they are said to be parallel. Lines that never cross paths with one another and do not have a common junction point are said to be parallel. Lines can either be parallel or intersecting. Two lines are said to intersect when they cross at a certain location in a plane. A line is referred to as a transversal line if it crosses two or more other lines at different locations.

Given that, JM is parallel to ST.

11 12 13 14 15 16 17 18 19 20

Answers

The box and whiskers plot is made up of five points: the minimum, the first quartile (Q1), the median (Med), the third quartile (Q3), and the maximum. The minimum is the lowest value in the dataset and the maximum is the highest value in the dataset.

What is median?

Median is the middle number in a set of numbers when the numbers are arranged in order from least to greatest. It is a type of measure of central tendency, which provides an indication of the “middle” value in a set of numbers. It is often used to measure the average of a set of numbers, particularly when there are extremely large or small values in the set.

The box and whiskers plot for this set of data is a visual representation of the data that makes it easier to interpret. The first quartile is the value that is 25% of the way through the dataset and the third quartile is the value that is 75% of the way through the dataset. The median is the middle value in the dataset.

To create a box and whiskers plot for this set of data, the minimum is 2, the first quartile is 4, the median is 5, the third quartile is 10, and the maximum is 14. The box and whiskers plot would then be represented by the following graph:

|                                 |

| 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 |

|    |    |    |    |    |    |    |    |    |    |

|  2 |  4 |  5 | 10 | 14 |

The box and whiskers plot graphically illustrates the spread of the data and allows us to easily compare the data to other datasets. It is also useful for identifying outliers in the dataset, as any value outside of the box and whiskers plot is considered an outlier.

1. The surface area of the pyramid is 115 cm²

(a) The area of the four triangles is 90 cm²

(b) The area of the square is 25 cm²

(c) The total surface area of the pyramid is 115 cm².

How to calculate the surface area of a pyramid?

To calculate the surface area of the pyramid, we use the formula below.

Formula:

A' = l²+[(4l)L)/2.......................... Equation 1

Where:

A' = Surface area of the pyramidl = length of the baseL = Slight height of the pyramid

From the question,

Given:

L = 9 cml = 5 cm

Substitute these values into equation 1

A' = 5²+[4×5×9)/2A' = 115 cm²

(a) To find the area of the 4 triangles, we use the formula below

At = 2bh..................... Equation 2

Where:

At = Area of the 4 trianglesb = Base of the triangleh = Height of the triangle

From the diagram,

Given:

b = 5 cmh = 9 cm

Substitute these values into equation 2

At = 2×5×9At = 90 cm²

(b) To find the area of the square, we use the formula below

As = b²

Where:

b = 5 cm

Substitute these values into equation

As = 5²As = 25 cm²

(c) To find the total surface area of the pyramid, we use the formula

At' = At+AsAt' = 90+25At' = 115 cm²

The congruency statement of the line congruent to VU is: VU ≅ VY

How to find the congruent line segment?

An isosceles triangle is defined as a triangle that has two sides of equal length and its corresponding angles are equal in measure .

When two straight lines are cut by a transversal, then the angles formed on the opposite side of the transversal with respect to both the lines are called alternate angles.

Thus:

∠TWU ≅ ∠YUW

By inspection, ΔTUW is an isosceles triangle and as such UT ≅ UW.

Since ∠TWU ≅ ∠YUW, then UY is parallel to TX. Thus:

UW ≅ YX and VU ≅ VY
