The number of keys required to fully implement a symmetric algorithm with 10 participants is: 45 (Option C)

Symmetric encryption or Algorithm is a kind of encryption that uses a single key (a secret key) to encrypt and decode electronic data.

The key must be exchanged between the organizations communicating using symmetric encryption so that it may be utilized in the decryption process.

The formula that determines the number of keys necessary for a symmetric algorithm is given as;

(n*(n-1))/2,

which is 45 in this situation, when n = 10.

That is

(10 * (10-1))/2

= 45.

Answer:

Step-by-step explanation:

An eleven-foot long board must be cut into three pieces so that one piece is 1-foot shorter than half the length of the longest piece and the other piece is 3 feet shorter than the longest piece. How long is the shortest piece?

board 1 = 0.5L - 1

board 2 = L - 3

board 3 = L

so:

(0.5L - 1) + (L - 3) + L = 11'

0.5L - 1 + L - 3 + L = 11'

combine L on left side:

2.5L - 4 = 11

add4 from both sides:

2.5L - 4 + 4 = 11 + 4

2.5L = 15

divide both sides by 2.5:

2.5L/2.5 = 15/2.5

L = 6

Formula for boards are, substitute in L = 6:

board 1 = 0.5L - 1

= 0.5(6) - 1

= 3 - 1

= 2'

board 2 = L - 3

= 6 - 3

3'

board 3 = L

= 6

shortest board is board 1 at 2'

The manufacturer needs to adjust the equipment to meet the standard with the margin of error of 2.34.

The calculated number known as the margin of error is added to and removed from the mean value to get the resulting confidence interval. The confidence interval expands as the margin of error does.

Calculate the 95% confidence interval's margin of error based on the aforementioned data.

α = 0.05

n = 20

s = 5

The following is the formula to determine the margin of error:

E = T(n-1) ×s/√n

The t-distribution table is used to determine the value of tn-1 at 19 degrees of freedom.

Replace the values in the formula above.

E = 2.093 ×5/√20

Thus, its margin of error is 2.34 as a result.

The size of the square that should be cut out of each corner to get a box with a maximum volume is 3 inches x 3 inches.

To calculate this, we need to first find the equation for the volume of the box in terms of the length of the square cut out from each corner. Let x be the length of the square cut out from each corner. Then the length of the base of the box is (63-2x) inches and the width of the base is (15-2x) inches. The height of the box is x inches.

The volume of the box is therefore given by:

V(x) = x(63-2x)(15-2x)

We need to find the value of x that maximizes the volume V(x). To do this, we take the derivative of V(x) with respect to x and set it equal to zero:

dV/dx = 6x² - 156x + 945 = 0

Solving this quadratic equation gives us:

x = 3 inches (ignoring the negative root)

Therefore, the size of the square that should be cut out of each corner to get a box with a maximum volume is 3 inches x 3 inches.

A computer manipulates data, doing arithmetic or logical operations on it. Computers are electronic devices that can input, store, process, and output data. They are capable of performing complex operations and calculations at a very high speed and accuracy.

The manipulation of data is a core function of a computer and is achieved through the use of specialized hardware and software. The central processing unit (CPU) of a computer is responsible for executing instructions and manipulating data. It consists of arithmetic logic units (ALUs) that perform arithmetic operations such as addition, subtraction, multiplication, and division, and logical operations such as AND, OR, NOT, and XOR. The CPU also contains registers, which are small, fast storage locations used to hold data temporarily during processing. Computer software, such as operating systems and applications, provide a means for users to manipulate data through a user interface. The software sends instructions to the CPU to perform various operations on the data, and then outputs the result to the user. Common software applications that manipulate data include spreadsheets, word processors, and database management systems. Overall, the ability to manipulate data is a crucial aspect of computing. It enables users to perform tasks such as data analysis, modeling, and simulation, which are essential in various fields such as science, engineering, and finance.

We can be 95% confident that the true population mean TV viewing time is between 3.812 and 4.388 hours.

To calculate the 95% confidence interval, we use the formula:

CI = x' ± Zα/2 * (σ/√n)

Where:

x' = sample mean

Zα/2 = the Z-score associated with the desired confidence level (in this case, 95%, so Zα/2 = 1.96)

σ = population standard deviation

n = sample size

Substituting the given values, we get:

CI = 4.1 ± 1.96 * (1.3/√78)

Calculating the standard error (SE) first:

SE = σ/√n

SE = 1.3/√78

SE ≈ 0.147

Then we substitute the SE value in the CI formula:

CI = 4.1 ± 1.96 * 0.147

CI = 4.1 ± 0.288

The equation that best models the situation is 2mmm + 5 = 333, where mmm represents the minutes spent digging a hole for a single rosebush.

Anna spent 333 hours in her garden planting 666 rosebushes. We can divide this into minutes by multiplying 333 by 60, which gives us 19980 minutes.

Since Anna spent twice as long digging the hole for each plant as she did refilling it, she spent an equal amount of time digging the hole for each rosebush and refilling it.

Therefore, if we let mmm represent the minutes spent digging the hole for a single rosebush, we can create an equation for the time spent digging the holes for all 666 rosebushes, which is 2mmm × 666.

We can then add the time spent refilling the holes, which is 5 minutes per rosebush, or 5 × 666.

This gives us our final equation of 2mmm × 666 + 5 × 666 = 19980.

We can then solve for mmm by dividing both sides by 1332, which gives us 2mmm + 5 = 333.

The value of angle S is 53°

Exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of two remote interior angles.

With this theorem we can say that

7x+2 = 4x+13+19

collecting like terms

7x -4x = 13+19-2

3x = 30

divide both sides by 3

x = 30/3

x = 10

Since x = 10

angle S = 4x+13

angle S = 4(10) +13
