Option a, adjacency matrix. An adjacency matrix is a two-dimensional array that represents a graph's edges, where the rows and columns correspond to the vertices of the graph. If there is an edge between two vertices, the corresponding element in the matrix is set to 1, otherwise it is set to 0. This implementation is useful for dense graphs, where the number of edges is close to the maximum possible number of edges.

An adjacency matrix is a simple and efficient way to represent graphs that have a large number of vertices and edges. It allows for fast lookups of the existence of an edge and is useful for various algorithms that require graph representation. However, it is not suitable for sparse graphs, where the number of edges is much smaller than the maximum possible number of edges. In such cases, an adjacency list would be more appropriate.

The common implementation of a graph that uses a two-dimensional array to represent the graph's edges is called an adjacency matrix.

To solve the equation 15 + 2x = 36, we can start by subtracting 15 from both sides of the equation to get 2x = 21. Then, we can divide both sides by 2 to get x = 10.5. Rounded to the nearest ten-thousandth, the solution is x = 10.5000.

Answer:

The center is at (3,1) and the radius is \(\sqrt{8}\)

Step-by-step explanation:

I am going to assume you meant to write

\((x-3)^2+(y-1)^2 = 8\)

Since if both variables were x it would not be a circle:

Then you can find the center and radius using the general formula of a circle:

\((x-h)^2 + (y-k)^2 = r^2\)

where the center is at (h,k) and r is the radius

Therefore:

The center is at (3,1) and the radius is \(\sqrt{8}\)

The first step is to organize the number, as follows:

The median is defined as the number which divides the group into two with the same number of terms. Because the number of terms is even, the median will be the mean of the two numbers in the middle, in the present case, 17 and 19.

From this, we conclude that the answer for the question a) is: 18.00

It was also possible to check that the number 108 is far bigger than any other. And for this reason, it is the outlier. If we remove it from the sample of data, we have the following sample:

Now, because the number of terms is odd, the one in the middle is the median. From this, we are able to conclude that the answer for question b) is: 17.00

The measure of  x and JR are 19 and 33  respectively

From the given parallelogram,

KM = 2KR

Given the following

Hence;

3x - 5  = 2(x+7)

3x - 5 = 2x + 14

3x - 2x = 14 + 5

x = 19

Similarly, JL = 2JR

JR = JL/2

JR = 4x-10/2

JR = 4(19)-10/2

JR = 66/2

JR = 33

Hence the measure of  x and JR are 19 and 33  respectively

Answer:

218.57

Step-by-step explanation:

Since it is an isoceles triangle, the sides are 32, 32, and 14.

Using Heron's Formula, which is Area = sqrt(s(s-a)(s-b)(s-c)) when s = a+b+c/2,  we can calculate the area.

(A+B+C)/2  = (32+32+14)/2=39.

A = sqrt(39(39-32)(39-32)(39-14) = sqrt(39(7)(7)(25)) =sqrt(47775)= 218.57.

Hope this helps have a great day :)

Answer:

Step-by-step explanation:

To find the explicit formula for the sequence 31, 27, 23, ..., we first need to find the common difference between consecutive terms.

We can see that each term is obtained by subtracting 4 from the previous term. Therefore, the common difference is -4.

Using the general formula for an arithmetic sequence:

an = a1 + (n - 1)d

where a1 is the first term, d is the common difference, and n is the index of the term we want to find.

In this sequence, a1 = 31 and d = -4. So, we have:

an = 31 + (n - 1)(-4)

Simplifying, we get:

an = 35 - 4n

Therefore, the explicit formula for the n-th term of the sequence 31, 27, 23, ... is an = 35 - 4n.

The probability that there will be at least 4 typos on page 301 is 0.847

To solve this problem, we need to make some assumptions. Let's assume that the number of typos on each page follows a Poisson distribution with a mean of 6 typos per page, and that the number of typos on one page is independent of the number of typos on any other page.

Under these assumptions, we can use the Poisson distribution to calculate the probability of observing a certain number of typos on a given page.

Let X be the number of typos on page 301. Then X follows a Poisson distribution with a mean of 6 typos per page. The probability of observing at least 4 typos on page 301 can be calculated as follows

P(X ≥ 4) = 1 - P(X < 4)

= 1 - P(X = 0) - P(X = 1) - P(X = 2) - P(X = 3)

Using the Poisson distribution formula, we can calculate the probabilities of each of these events

P(X = k) = (e^-λ × λ^k) / k!

where λ = 6 and k is the number of typos. Thus,

P(X = 0) = (e^-6 × 6^0) / 0! = e^-6 ≈ 0.0025

P(X = 1) = (e^-6 × 6^1) / 1! = 6e^-6 ≈ 0.015

P(X = 2) = (e^-6 × 6^2) / 2! = 18e^-6 ≈ 0.045

P(X = 3) = (e^-6 × 6^3) / 3! = 36e^-6 ≈ 0.091

Plugging these values into the equation above, we get

P(X ≥ 4) = 1 - (e^-6 + 6e^-6 + 18e^-6 + 36e^-6)

≈ 0.847

Step-by-step explanation:

The term that best matches the description provided is "object."

An object is a unit of data that represents an abstraction or a real-world entity, such as a person, place, or thing. In object-oriented programming, objects are instances of classes and contain attributes (data) and methods (functions) that define their behavior. Therefore, among the options given, "object" is the correct choice.

what is functions?

In mathematics and computer science, a function is a relationship between a set of inputs (called the domain) and a set of outputs (called the range) such that each input is associated with exactly one output. Functions are used to describe and model various phenomena and processes.

A function typically takes one or more input values, performs a specific operation or transformation on them, and produces an output value. The input values are often referred to as arguments or parameters, and the output value is the result of applying the function to the given inputs.

Answer:

(10,24)

Step-by-step explanation:

Well first we plug in y = 3x - 6 for y in y = 2x + 4

3x - 6 = 2x + 4

Then we combine like terms and seperate x.

x - 6 = 4

x = 10.

If x is 10 we plug that in

y = 3(10) - 6

y = 30 -6

y = 24

Answer:

Step-by-step explanation:

The coordinates went from (4,1) to (-4,-1). This means it went from (x,y) to (-x,-y)

The final result is 144 = 8 √2x with the domain being all the real values of x greater than or equal to zero.

The given expression is (8+)² 4* = V2* 2x 16 domain.

We need to simplify this expression.

Given expression is:

(8+)² 4* = V2* 2x 16 domain.    

= (8 + 4)²= 12²

= 144

We know that

V16 = 4

∴ V2 * 16 = 2 * 4

= 8

Thus, (8+)² 4* = V2* 2x 16 domain becomes,

144 = 8 √2x

The domain is all the real values of x greater than or equal to zero.

The reason behind taking x greater than or equal to zero is that square roots of negative numbers are imaginary numbers which are not considered in real analysis.
