Step-by-step explanation:

slope =3/2

that is the answer

Answer:

y+2/3=9/7(x-0)

Step-by-step explanation:

1. Find the slope

 \(\frac{-6-3}{-2-5} = \frac{-9}{-7} = \frac{9}{7}\)

2. Since they are parallel the slopes are the same

3. Insert slope and y-intercept into slope intercept form y-y=m(x-x)

 y-(-2/3)=9/7(x-(0))

4. Since I am too lazy to look for another point I will use the intercept point (0,-2/3)

5. Simplify

y+2/3=9/7(x-0)

The encryption method that combines a random value with the plain text to produce the cipher text is: One-time pad.

The one-time pad encryption technique is a form of symmetric encryption where a random key, known as the one-time pad, is combined with the plain text using a bitwise XOR operation. The one-time pad should be at least as long as the plain text and should never be reused.

In this method, each character of the plain text is combined with a corresponding character from the one-time pad, resulting in the cipher text. The one-time pad acts as a random key stream, making the encryption extremely secure if implemented correctly.

Steganography is a different technique that involves hiding information within other seemingly innocuous data, such as images or audio files, without necessarily encrypting it.

Transposition is a method of encryption where the characters of the plain text are rearranged or shuffled without changing the actual characters themselves.

Elliptic Curve is not an encryption method but rather a mathematical framework used in public-key cryptography systems, such as Elliptic Curve Cryptography (ECC), which provide secure communication channels but do not involve combining random values with the plain text to produce the cipher text.

Therefore, the correct answer is: One-time pad.

y = (1/3)x + 2

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b, where y and x are variables, m is the slope of the line, that is the ratio of the change in vertical distance to horizontal distance while b is the y intercept of the graph.

From the graph, we can see that the y intercept (where the graph touches the y axis) is 2. Hence b = 2

Also, the slope (m) = change in y / change in x = 1 / 3

The equation of the line is:

y = (1/3)x + 2

Answer:y = (1/3)x + 2

The probability that both Michelle and Garth will drive a red bumper car is 1/22.

The bumper car ride at the state fair has 3 red cars, 4 green cars, and 5 blue cars. Michelle is first in line for the ride and is assigned a car at random. Garth is next in line and is randomly assigned a car. We have to find the probability that both Michelle and Garth will drive a red bumper car.

Probability of Michelle driving a red car = 3/12 or 1/4Probability of Garth driving a red car after Michelle has been assigned a red car is = 2/11 Let A be the event of Michelle driving a red car and B be the event of Garth driving a red car. Then, we have to find P(A and B). P(A and B) = P(A) * P(B after A)⇒ P(A and B) = 1/4 * 2/11⇒ P(A and B) = 1/22 Therefore, the probability that both Michelle and Garth will drive a red bumper car is 1/22.

Answer:

A)a rectangle 5 inches by 6 inches to get the results

Answer:

Sure! Let’s solve this equation step by step.

(7000).03 + (x).05=830

First, we can simplify the left side of the equation:

210 + 0.05x = 830

Next, we can subtract 210 from both sides:

0.05x = 620

Finally, we can divide both sides by 0.05 to solve for x:

x = 12400

So the solution to the equation (7000).03 + (x).05=830 is x = 12400.

If a = 6 - \(\sqrt{35} \), find the value of a² + \( \frac{1}{a²} \)

a = 6 - \(\sqrt{35} \) (Given)

Now, first of all we have to find the value of \( \frac{1}{a} \).

So, \( \frac{1}{a} \) = \( \frac{1}{6 \: - \: \sqrt{35}} \)

\( \frac{1}{a} \) = \( \frac{6 \: + \sqrt{35}}{(6 \: - \: \sqrt{35})(6 \: + \: \sqrt{35})} \)

\( \frac{1}{a} \) = \( \frac{6 \: + \sqrt{35}}{(6)² \: - \: (\sqrt{35})²} \)

\( \frac{1}{a} \) = \( \frac{6 \: + \sqrt{35}}{36 \: - \: 35} \) \( (\because \sqrt{35} \: × \: \sqrt{35} \: = \: 35) \)

\( \frac{1}{a} \) = \( \frac{6 \: + \: \sqrt{35}}{1} \)

\( \frac{1}{a} \) = 6 + \(\sqrt{35} \)

Now, we have to find the value of a² + \( \frac{1}{a²} \)

So, a² + \( \frac{1}{a²} \) = \( (a \: + \frac{1}{a})² \) - 2.a.\( \frac{1}{a} \)

a² + \( \frac{1}{a²} \) = \( (6 \: - \sqrt{35} \: + \: 6 \: + \sqrt{35})² \) - 2

a² + \( \frac{1}{a²} \) = (12)² - 2

a² + \( \frac{1}{a²} \) = 144 - 2

a² + \( \frac{1}{a²} \) = 142

The value of a² + \( \frac{1}{a²} \) is 142. [Answer]

Answer:

2.5(x)/10 = 50/200

Step-by-step explanation:

hope that helps :)

So 50/200=0.25

therefore, x has to be divided by 10 and be equal to that number, so 2.5/10=0.25 but let's do it with steps

1) Simplify or combine like terms (in this case we need to simplify 50/200 which is 0.25)

2) To isolate x, do the opposite operation on BOTH SIDES.

x/10 ×10 cancels out the 10

x=0.25×10

x=2.5

Answer:

Neither

Step-by-step explanation:

-12x + 3y = 3

y = 4x + 1

y = mx + b

The second equation given is set up in the correct form already (y = 4x + 1)

We have to convert the first equation into the same format

-12x + 3y = 3

Isolate the y

3y = 3 + 12x

Divide the 3 from the y and the other side

y = 1 + 4x

y = 4x + 1

This is the same as the first equation

They can only be parallel if their slope (m or 4 in this case) is the same and their y-intercepts (b or 1 in this case) are different. Since the equations are the exact same and do not fit the y-intercept criteria for parallel, they cannot be parallel. If they were perpendicular, their lines must cross. This means they have to contain reciprocals or opposite slopes. Our slope here for both of them is 4 or 4/1. Since neither are the opposite (which would be 1/4), it is not perpendicular. Therefore, the answer is neither

Step-by-step explanation:

The probability of winning at least one award is 1 - 0.2373 = 0.7627 or 76.27%.

If the probability of winning an MTV music award after being nominated is 25%, the probability of not winning is 75%. Thus, the probability of not winning any of the five awards is (0.75)^5 = 0.2373.

As for how many awards Ariana Grande should expect to win, we can use the expected value formula: E(x) = n * p, where n is the number of trials (in this case, 5) and p is the probability of success (0.25). Therefore, E(x) = 5 * 0.25 = 1.25. So, Ariana Grande can expect to win about 1 award.

Finally, to calculate the standard deviation associated with this probability, we can use the formula: σ = sqrt(n * p * (1-p)). Plugging in the values, we get σ = sqrt(5 * 0.25 * 0.75) = 0.866. Therefore, the standard deviation associated with this probability is approximately 0.866.

the area of trapezoid efgh is given by the expression 3 * 12^2 / (x + 12) cm^2.

Let's denote the length of ab as x. Since line dc is twice the height of trapezoid abcd and four times the length of ab, its length is 2 * 6 = 12 cm. Additionally, line dc is also the sum of the lengths of ef and gh. Thus, we have ef + gh = 12 cm.

Since trapezoid abcd is proportional to trapezoid efgh, the ratio of their areas is equal to the square of the ratio of their corresponding side lengths. Therefore, (Area of efgh) / (Area of abcd) = (ef + gh)^2 / (ab + cd)^2.

Plugging in the values, we have (Area of efgh) / (Area of abcd) = (12)^2 / (x + 12)^2.

Given that the height of abcd is 6 cm, its area is (1/2) * (ab + cd) * 6 = (1/2) * (x + 12) * 6 = 3(x + 12) cm^2.

Multiplying both sides of the proportionality equation by the area of abcd, we get (Area of efgh) = (Area of abcd) * [(ef + gh)^2 / (ab + cd)^2].

Substituting the values, we find (Area of efgh) = 3(x + 12) * [(12)^2 / (x + 12)^2].

Simplifying further, we get (Area of efgh) = 3 * 12^2 / (x + 12).

Therefore, the area of trapezoid efgh is given by the expression 3 * 12^2 / (x + 12) cm^2.

The sum of the given two positive integers is 9.

According to the question,

We have the following information:

The product of two positive integers is 18. the positive difference of these two integers is 3.

Now, let's take the first positive integer (larger one) to be x and the second positive integer to be y.

xy = 18 ...(1)

x-y = 3

x = 3+y

Putting this value in equation 1:

(3+y)y = 18

\(y^{2} +3y-18 = 0\)

\(y^{2}\)+6y-3y-18 = 0

y(y+6)-3(y+6) = 0

(y+6) (y-3) = 0

y-3 = 0 and y+6 = 0

y = 3 or y = -6

Now, the number is positive so it will be 3.

Putting this value in equation 1:

xy = 18

3x = 18

Dividing by 3 on both sides of the equation:

x= 18/3

x = 6

Sum of integers = 3+6

Sum of integers = 9

The context that could not be modeled by a linear function is: a town's population shrinks at a rate of 7.9% every year.

A linear function represents a relationship where the change in one variable is directly proportional to the change in another variable. In the given contexts:

However, the context of a town's population shrinking at a rate of 7.9% every year cannot be modeled by a linear function. The population change in this scenario is not constant but rather decreases by a percentage each year. The population decline would follow an exponential or logarithmic function, as the rate of decrease is proportional to the existing population size.

Out of the given contexts, the town's population shrinking at a rate of 7.9% every year cannot be accurately modeled by a linear function. Linear functions are suitable for situations with constant rates of change, while exponential or logarithmic functions are better suited for representing population changes that involve percentages or growth/decay rates.
