Answer:

? = 92°

Step-by-step explanation:

the chord- chord angle ? is half the sum of the measures of the arcs intercepted by the angle and its vertical angle, that is

? = \(\frac{1}{2}\) (LM + AK) = \(\frac{1}{2}\) (120 + 64)° = \(\frac{1}{2}\) × 184° = 92°

The equation of the line perpendicular to y = 5x + 4, passing through the point (1, -2), is y = (-1/5)x - 9/5.

To find an equation in slope-intercept form that passes through the point (1, -2) and is perpendicular to the given equation y = 5x + 4, we need to determine the slope of the perpendicular line.

The given equation y = 5x + 4 is already in slope-intercept form (y = mx + b), where m represents the slope. In this case, the slope of the given line is 5.

To find the slope of a line perpendicular to this, we use the fact that the product of the slopes of two perpendicular lines is -1. So, the slope of the perpendicular line can be found by taking the negative reciprocal of the slope of the given line.

The negative reciprocal of 5 is -1/5.

Now that we have the slope (-1/5) and a point (1, -2), we can use the point-slope form of the equation:

y - y1 = m(x - x1)

Substituting the values:

y - (-2) = (-1/5)(x - 1)

Simplifying:

y + 2 = (-1/5)(x - 1)

To convert the equation into slope-intercept form (y = mx + b), we need to simplify it further:

y + 2 = (-1/5)x + 1/5

Subtracting 2 from both sides:

y = (-1/5)x + 1/5 - 2

Combining the constants:

y = (-1/5)x - 9/5

Therefore, the equation of the line perpendicular to y = 5x + 4, passing through the point (1, -2), is y = (-1/5)x - 9/5.

The correct answer is (j - k)(x) = 10 + x.

To find the difference in the amount of money between Joel's and Kevin's accounts, we subtract the value of Kevin's account (k(x)) from Joel's account (j(x)).

(j - k)(x) = (25 + 3x) - (15 + 2x)

            = 25 - 15 + 3x - 2x

The mean number of workers with a college degree is 40.8, and the standard deviation is 5.37.

The probability that the number of workers with a college degree is at least 35 is 0.976, or 97.6%.

Given Sample size (n) is 120 workers

Proportion of workers who are college graduates (p): 34% or 0.34

a) Mean and Standard Deviation:

The mean (μ) of a binomial distribution is given by μ = np, and the standard deviation (σ) is given by σ =√np(1 - p).

Substituting the values:

μ = 120 ×0.34 = 40.8

σ = √120 × 0.34 × (1 - 0.34)) = 5.37

To find the probability that the number of workers with a college degree is at least 35

we need to calculate the cumulative probability of the binomial distribution from 35 to the maximum possible value, which is 120 in this case.

Using a binomial probability calculator or a statistical software, we can find this probability.

Assuming a binomial distribution with parameters n = 120 and p = 0.34, the probability can be calculated as follows:

P(X ≥ 35) = 1 - P(X < 35)

The probability that the number of workers with a college degree is at least 35 is 0.976, or 97.6%.

Answer:

Option A is the correct answer.

Step by step explanation :

It's given that Stacy is 3 years younger than twice her sister's age.

Let's consider her sister's age to be 'x'

So Stacy's age = 2x - 3

Since Stacy's age is 13, we get

13 = 2x - 3

Or 2x - 3 = 13

Answer:

The correct answer is x=3 trust me. Im good at math got 1st place on 1v1 equations in my school hope this helped.

Step-by-step explanation:

Answer:

\(\boxed {\tt x=3}\)

Step-by-step explanation:

We want to solve for x, therefore we must isolate the variable.

We are given the equation:

\(\frac{2x}{3} +1=3\)

1 is being added to 2x/3. The inverse of addition is subtraction. Subtract 1 from both sides of the equation.

\(\frac{2x}{3}+1-1=3-1\)

\(\frac{2x}{3} =2\)

2x is being divided by 3. The inverse of division is multiplication. Multiply both sides by 3.

\(3*\frac{2x}{3} =2*3\)

\(2x=2*3\)

\(2x=6\)

x is being multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.

\(\frac{2x}{2} =\frac{6}{2}\)

\(x=\frac{6}{2}\)

\(x=3\)

The solution to the equation is x=3.

Irene has 49 Books, and Alejandro has 24 books.

Let's assume that Irene has x books, and Alejandro has y books. According to the given information, we can form the following equations:

1. Irene has twice as many books as Alejandro plus 1:

  x = 2y + 1

2. The total number of books between Irene and Alejandro is 73:

  x + y = 73

We can now solve this system of equations to find the values of x and y.

Substituting the value of x from equation (1) into equation (2), we have:

(2y + 1) + y = 73

3y + 1 = 73

3y = 72

y = 24

Now, we can substitute the value of y into equation (1) to find x:

x = 2(24) + 1

x = 49

Therefore, Irene has 49 books, and Alejandro has 24 books.

To verify our solution, we can check if the sum of their books equals 73:

49 + 24 = 7

So, our solution is correct.

In conclusion, Irene has 49 books, and Alejandro has 24 books.

Where h is the number of hours and t is the number of transformers.

Since he worked for 36 hours and assembled 380 transformers:

Total earnings = 9.25 (36) + 8 (380/20)

Total earnings = 333+152 = $485

A={x EZ: (2x-2)} is a set notation that describes the set of all integers x that satisfy the condition (2x-2).

To find all the elements in this set, we can substitute in integers for x and check which ones satisfy the condition.

2x - 2 = 0

2x = 2

x = 1

So, the element in set A is {1}.

The set A contains only one element, which is x = 1, as it is the only integer value that satisfies the condition (2x-2) = 0.

It's also worth noting that a set can also be empty, in that case it would be written as a empty set and denoted by {}.

Samira will need 14.1 square meters of carpeting to cover the empty space in her bedroom.

Samira wants to carpet her bedroom, and she wants to know the amount of carpeting in square meters needed to cover the empty space in the room. The dimensions of the bed and closet are given in the table.

To determine the amount of carpet needed to cover the empty space in the bedroom, we must first calculate the area of the room. To do this, we will multiply the length and width of the room, excluding the bed and closet.

The width of the room is 3.6 m and the length is 5.2 m. The area of the room is therefore: Area of room = length × widthArea of room = 5.2 m × 3.6 mArea of room = 18.72 m²To determine the amount of carpet needed to cover the empty space in the bedroom, we must subtract the area of the bed and closet from the area of the room.

Area of bed = length × width Area of bed = 2 m × 1.5 mArea of bed = 3 m²Area of closet = length × width Area of closet = 1.8 m × 0.9 mArea of closet = 1.62 m²Total area of bed and closet = 3 m² + 1.62 m²Total area of bed and closet = 4.62 m²Area of empty space = area of room - total area of bed and closet Area of empty space = 18.72 m² - 4.62 m²Area of empty space = 14.1 m²

The shortest distance between the two points is √[(c + 5)² + (6 - d)²]

From the question, we have the following points that can be used in our computation:

G = (c, 6) and H = (-5, d)

The distance between the two points can be calculated using the following distance equation

distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Where

(x, y) = (c, 6) and (-5, d)

Substitute (x, y) = (c, 6) and (-5, d) in distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

distance = √[(c + 5)² + (6 - d)²]

Hence, the distance expression is √[(c + 5)² + (6 - d)²]

Step-by-step explanation:

Caludia needs to pay 2917.6128 as a payment of compound interest capital+interest.

What is compound interest?

compound interest is interest on principal + interest and this denotes to the addition of interest to the principal amount of a loan or deposit.

Capital(p) = $6400

Rate of interest(r) = 11%

Years(n) = 3

The general formula of compound interest is \(A= p(1+\frac{r}{100}})^n\).

Now

\(A= 6400(1+\frac{11}{100}})^3\\A=6400 \times \frac{111}{100} \times \frac{111}{100} \times \frac{111}{100}\\A= 8752.8384\)

The entire amount (Capital+interest) is equal to $8752.8384.

If we take 1 year as a period then Claudia needs to pay \(\frac{8752.8384}{3}\\=2917.6128\)

Therefore, Claudia needs to pay 2917.6128 as a payment of compound interest capital+interest.
