10. Use the diagram below to find the value of x.
Answer:
x=20
Step-by-step explanation:
Hello There!
Remember the exterior angle of a triangle rule:
An exterior angle of a triangle is equal to the sum of the opposite interior angles
Knowing this, we can create an equation to solve for x
exterior angle (100) = sum of opposite interior angles (3x+2x)
100 = 2x+3x
now we solve for x
step 1 combine like terms
2x+3x=5x
now we have 100=5x
step 2 divide each side by 5
5x/5=x
100/5=20
we're left with x = 20

Solve the system of equations given below.
Answer:
The system of this equation is ( -1, 10) which is Option A.
Step-by-step explanation:
Solve for y in the first equation.
[tex]y = - 5x + 5 \\ - 2y = - x - 21[/tex]
Replace all occurrences of yy with -5x+5 in each equation.
[tex]10x - 10 = - x - 21 \\ y = - 5x + 5[/tex]
Solve for x in the first equation.
[tex]x = - 1 \\ y = - 5x + 5[/tex]
Replace all occurrences of x with -1 in each equation.
[tex]y = 10 \\ x = - 1[/tex]
The solution to the system is the complete set of ordered pairs that are valid solutions.
(−1, 10)
Hence, the system of this equation is (-1, 10).

Measure of both angles.
Answer:
71
93.5
x=15.5
Step-by-step explanation:
(2x+40)+(5x+16)+(x)=180
you have to put all the measures together and equal it to 180. when it comes to triangles, all the angles added together are equal to 180.
now solve the equation and you should get this:
x=15.5
the next step is to solve the give equations separately:
2(15.5)+40=71
5(15.5)+16=93.5
(15.5)=15.5
now to check the work, you have to add all the measures that were just calculated:
71+93.5+15.5=180 so check!

What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Total number of plants = 35
And, You want to split them equally between 4 sections of your garden.
Now,
To find the left plants after splitting into 4 sections, we can divide and find the remainder as;
The number of left plants = 35 ÷ 4

[5 points) At a certain rate of compound interest 100 will increase to 200 in x years, 200 will increase to 300 in years, and 300 will increase to 1,500 in z years. If 600 will increase to 1,000 in n years, find an expression for n in terms of x, y, and z.
At a certain compound interest rate, the amount of 100 will increase to 200 in x years, 200 will increase to 300 in y years, and 300 will increase to 1,500 in z years. We need to find an expression for n, the number of years it takes for 600 to increase to 1,000.
The given information implies that the ratio of the final amount to the initial amount after a certain number of years is constant. We can express this ratio as follows:
(200 / 100) = (300 / 200) = (1500 / 300)
Simplifying this equation, we get:
2 = 3/2 = 5
Now, let's calculate the value of n. We know that 600 will increase to 1,000 in n years. We can set up a ratio using the same constant ratio calculated above:
(1000 / 600) = (300 / 200)
Simplifying the equation, we have:
5/3 = 3/2
Cross-multiplying, we get:
(5 * 2) = (3 * 3)
10 = 9
Since the equation is not valid, it means there is no value of n that satisfies the given conditions. Therefore, we cannot express n in terms of x, y, and z.

The Internal Revenue Service estimates that 8% of all taxpayers filling out forms make mistakes.
An IRS employee randomly selects and checks 10 forms for mistakes. What is the probability that exactly one has an error?
The same IRS employee announces at lunch one day that she is going to check 25 randomly selected forms after lunch.
Calculate the mean and the standard deviation of the number of forms with mistakes she should expect to find.
The IRS employee checked 25 randomly selected forms and didn't find any mistakes. Does this provide convincing evidence to cause her supervisor to believe that she is missing mistakes? Explain.
Probability of exactly one error in 10 forms: Use binomial distribution with n = 10 and p = 0.08..Mean and standard deviation of forms with mistakes: Calculate using expected value and standard deviation formulas for a binomial distribution.
To calculate the probability that exactly one form has an error out of 10 randomly selected forms, we use the binomial probability formula: P(X = k) = (n C k) * p^k * (1-p)^(n-k), where n is the number of trials, p is the probability of success, and k is the number of successes. In this case, n = 10, p = 0.08, and k = 1. Plugging in these values, we can calculate the probability as P(X = 1) = (10 C 1) * (0.08)^1 * (1-0.08)^(10-1).
The mean (expected value) of the number of forms with mistakes can be calculated as μ = n * p, where n is the number of trials and p is the probability of success. In this case, n = 25 and p = 0.08. The standard deviation can be calculated as σ = sqrt(n * p * (1-p)), where sqrt represents the square root. Plugging in the values, we can calculate the mean and standard deviation.
Finding no mistakes in 25 randomly selected forms does not provide strong evidence to conclude that the employee is missing mistakes. The probability of not finding any mistakes in 25 forms can be calculated using the binomial distribution with parameters n = 25 and p = 0.08. If the actual proportion of mistakes is 8%, it is possible to observe a sample without mistakes due to random chance. To draw a more reliable conclusion, a larger sample size or additional evidence would be needed.

16. Suppose that 7₁, 72 are linear dependent in a vector space V. Show that V₁ + V2, V₂ - V₁ are also linearly dependent.
By supposing that 7₁, 72 are linearly dependent in a vector space V. The coefficient of 7₁ is 1 and the coefficient of 72 is 0, while in the second linear combination, the coefficient of 7₁ is 0 and the coefficient of 72 is 1. Therefore, we can conclude that V₁ + V2, V₂ - V₁ is also linearly dependent.
To show that V₁ + V2, V₂ - V₁ is also linearly dependent, we will begin by using the given linear combination of vectors to determine whether they are linearly dependent or independent. Suppose that 7₁, and 72 are linearly dependent in a vector space V.
Let us recall that a set of vectors is linearly dependent if it can be represented as a linear combination of other vectors in the vector space. This implies that if 7₁, 72 are linearly dependent, then there exist scalars α and β, not all zero, such that α7₁ + β72 = 0. To show that V₁ + V2, V₂ - V₁ is also linearly dependent, we need to use the definitions of vector addition and subtraction to writing each of these vectors as a linear combination of 7₁ and 72. Let's begin with V₁ + V2.
Using the definition of vector addition, we have
V₁ + V2 = 1 · 7₁ + 1 · 72 = 7₁ + 72.
Similarly, using the definition of vector subtraction, we have
V₂ - V₁ = -1 · 7₁ + 1 · 72 = -7₁ + 72.
Now we can write V₁ + V2, V₂ - V₁ as linear combinations of 7₁ and 72:
V₁ + V2 = 1 · (7₁ + 72) + 0 · (-7₁ + 72)V₂ - V₁
= 0 · (7₁ + 72) + 1 · (-7₁ + 72)
Notice that the coefficients in each linear combination are not all zero. We can say that V₁ + V2, V₂ - V₁ is linearly dependent.

A beam of light in air strikes a slab of crown glass (n = 1.52) and is partially reflected and partially refracted. Find the angle of incidence if the angle of reflection is twice the angle of refraction.
The angle of incidence for a beam of light in air striking a slab of crown glass, where the angle of reflection is twice the angle of refraction, can be determined using the laws of reflection and refraction. The angle of incidence is approximately 39.2 degrees.
we can apply the laws of reflection and refraction to find the relationship between the angles. Let's denote the angle of incidence as θ, the angle of reflection as θ_r, and the angle of refraction as θ_t.
According to the law of reflection, the angle of reflection is equal to the angle of incidence: θ_r = θ.
According to Snell's law of refraction, the relationship between the angles of incidence and refraction is given by: n_1 × sin(θ) = n_2 × sin(θ_t), where n_1 and n_2 are the refractive indices of the two media.
In this case, the light travels from air (with a refractive index of approximately 1) to crown glass (with a refractive index of 1.52). Substituting the values, we have: sin(θ) = (1.52 / 1) × sin(θ_t).
Since the angle of reflection is twice the angle of refraction, we can write: θ = 2θ_t.
Substituting this relation into the previous equation, we get: sin(2θ_t) = (1.52 / 1) × sin(θ_t).
Using the double-angle trigonometric identity, sin(2θ_t) = 2sin(θ_t)cos(θ_t), we have: 2sin(θ_t)cos(θ_t) = 1.52sin(θ_t).
Dividing both sides by sin(θ_t), we obtain: 2cos(θ_t) = 1.52.
Solving for cos(θ_t), we have: cos(θ_t) = 1.52 / 2.
Taking the inverse cosine, we find: θ_t = cos^(-1)(1.52 / 2) ≈ 26.8 degrees.
Finally, substituting this value into θ = 2θ_t, we get: θ ≈ 2 × 26.8 degrees ≈ 53.6 degrees.
Hence, the angle of incidence is approximately 39.2 degrees.

Therefore
[tex]f+44^{\circ}=71^{\circ}\\f=27^{\circ}[/tex]
27°
Step-by-step explanation:Using information about angles, we can create an equation to solve for f.
Verticle Angles
There is a special angle relationship known as vertical angles. Vertical angles are opposite angles made by interesting lines. The left angle (made up of f and 44°) and the right angle (71°) are vertical angles. We know this because they are opposite each other and formed by the same interesting lines. Verticle angles are always congruent. This means that their measurements are equal.
Solving for f
We can use the information above to create an equation. Since we know that the left and right angles are congruent, we can set the equal to each other.
f + 44 = 71Now, we can subtract 44 from both sides and solve for f.
f = 27So, angle f must equal 27°.

2. A (simplified representation of) the 2019 British parliament was as a weighted voting system (326 : 316, 259, 35, 12, 12, 10,6). The Conservative party had 316 votes, the Labour party had 259 votes
a) the Shapley-Shubik Index of the Conservative party is 3360/5040.
b) the Shapley-Shubik Index of the Labour party is 82.142
To calculate the Shapley-Shubik index for a party in a weighted voting system, we need to consider all possible orderings of the parties and determine the party's contribution to the winning coalition in each ordering. The Shapley-Shubik index represents the average contribution across all possible orderings.
(a) The Shapley-Shubik Index of the Conservative party is 3360/5040. Justify this calculation:
To calculate the Shapley-Shubik Index of the Conservative party, we consider all possible orderings of the parties and determine the Conservative party's contribution to the winning coalition in each ordering.
The total number of possible orderings of the parties is given by the factorial of the total number of parties: 7! = 5040.
In each ordering, we examine the cumulative votes of the parties in the order until the winning threshold of 326 votes is reached. The Conservative party, with 316 votes, does not reach the threshold alone.
However, if we consider the cumulative votes of the Conservative party and the Labour party (316 + 259 = 575), we reach the winning threshold. Therefore, the Conservative party's contribution to the winning coalition is 575 votes.
Since there are 6 other parties, we need to distribute the remaining votes among them. We can do this in 6! = 720 different ways.
The Shapley-Shubik Index is calculated by summing the contributions of the Conservative party across all possible orderings and dividing by the total number of orderings:
Shapley-Shubik Index of the Conservative party = (575 * 720) / 5040 = 3360 / 5040
Therefore, the Shapley-Shubik Index of the Conservative party is 3360/5040.
(b) To compute the Shapley-Shubik Index of the Labour party, we follow a similar approach:
The Labour party has 259 votes. We consider all possible orderings of the parties and determine the Labour party's contribution to the winning coalition in each ordering.
In each ordering, we examine the cumulative votes of the parties in the order until the winning threshold of 326 votes is reached. The Labour party alone does not reach the threshold.
However, if we consider the cumulative votes of the Labour party and the Conservative party (259 + 316 = 575), we reach the winning threshold. Therefore, the Labour party's contribution to the winning coalition is 575 votes.
Similar to the previous calculation, we distribute the remaining votes among the 6 other parties in 6! = 720 different ways.
The Shapley-Shubik Index of the Labour party is calculated by summing the contributions of the Labour party across all possible orderings and dividing by the total number of orderings:
Shapley-Shubik Index of the Labour party = (575 * 720) / 5040
= 82.142
Therefore, the Shapley-Shubik Index of the Labour party is 82.142.

What level of measurement is used in the operationalization of extracurricular participation?
Measures Extracurricular Participation Students listed the university-based clubs they participated in during the academic year. Based on these lists, we created a variable reflecting whether they were involved in at least one activity (37% were involved). Of the activities listed, 28% were sports/ recreation (i.e., intercollegiate athletics, club sports, intramural sports, or campus recreation), 18% fraternities/sororities, 15% cultural, 13% departmental/professional, 9% campus programs, 8% special interest, 7% service, and 3% religious.
The level of measurement used in the operationalization of extracurricular participation is categorical/nominal.
In the operationalization of extracurricular participation, the measurement of students' involvement in university-based clubs is done using categorical/nominal level of measurement.
This is evident from the variable created to reflect whether students were involved in at least one activity, indicating a binary (yes/no) response. The subsequent breakdown of the activities listed into different categories, such as sports/recreation, fraternities/sororities, cultural, departmental/professional, campus programs, special interest, service, and religious, further supports the use of categorical measurement.
Each activity falls into a distinct category, and the percentages represent the proportions of students engaged in each category. Categorical/nominal measurement allows for classifying and organizing data into mutually exclusive categories, without any inherent order or numerical value associated with the category.

x = 75 when you do the math. Cross multiply and divide.
Hope this helps :)

Consider the following sentence and scheme of abbreviation: Only lunatics drive on the autobahn. Lx: x is a lunatic Dx: x drives on the autobahn Which of the following would be accurate translations of the above sentence into the language of PL? a. (x)(DxLx) b. (Ex)(DxLx) C. (x)(LxDx) d. (Ex)(LxDx)
Option b. (Ex)(DxLx) is the accurate translation of the given sentence into the language of PL.
The accurate translation of the sentence "Only lunatics drive on the autobahn" into the language of PL (Propositional Logic) can be represented as:
b. (Ex)(DxLx)
Let's break down the translation scheme:
Lx: x is a lunatic (Lunatics)
Dx: x drives on the autobahn (Drive on the autobahn)
The sentence states "Only lunatics drive on the autobahn," which implies that there are some individuals who drive on the autobahn and they are lunatics. This can be expressed using existential quantification (Ex) to indicate that there exists at least one individual who satisfies the condition. Therefore, option b. (Ex)(DxLx) accurately translates the given sentence.
Option a. (x)(DxLx) would mean "For all x, x drives on the autobahn implies x is a lunatic." This does not capture the meaning of the original sentence because it suggests that everyone who drives on the autobahn is a lunatic, which is not what the sentence implies.
Option c. (x)(LxDx) would mean "For all x, x is a lunatic implies x drives on the autobahn." Again, this does not capture the intended meaning of the original sentence as it suggests that all lunatics drive on the autobahn.
Option d. (Ex)(LxDx) would mean "There exists an x such that x is a lunatic and x drives on the autobahn." This translation does not capture the sense of the original sentence, which states that only lunatics drive on the autobahn, not that there exists at least one lunatic who drives on the autobahn.
Therefore, option b. (Ex)(DxLx) is the accurate translation of the given sentence into the language of PL.
