As calculated from the data (1/6)² is the probability of getting 5 of same number on all the dice.

b.)If we will limit the number of winners then we will be able to provide them with large prizes and that also by taking moderate rate from everyone.

Actually, the likelihood of winning is closer to one-third (25/72).

Carnival game organizers want you to believe, like I did, that a game is fair so that you will participate.

The likelihood that you would win a game was just about 1/3, so you probably wouldn't squander your money.

Therefore,

The likelihood of getting five of the same number on all six dice is (1/6)².

Probabilities are mathematical representations of the likelihood that an event will occur or that a statement is true.

Probability can also be expressed using a tree diagram.

Answer:

Since Adil takes 25 seconds to complete the race, and Tom takes 24 seconds, Tom wins the race.

Step-by-step explanation:

To determine who wins the race, we need to first convert the given information into comparable units. The speed of Adil is given in kilometers per hour, while the time taken by Tom to complete the race is given in seconds. We can convert Adil's speed to meters per second by dividing by 3.6:

28.8 km/hr = 28.8 km/hr * (1 hour / 3600 seconds) * (1000 meters / 1 km)

         = 8 meters/second

We can then use this value to find the time it takes Adil to complete the race:

time = distance / speed

   = 200 meters / 8 meters/second

   = 25 seconds

Since Adil takes 25 seconds to complete the race, and Tom takes 24 seconds, Tom wins the race.

382^2 mod

Step-by-step explanation:

To determine the shared secret key, we need to use the formula (g^a mod p)^b mod p = (g^b mod p)^a mod p, where g is the generator, p is the prime, a is our secret number, and b is the value sent by Aisha. Plugging in the values, we get (7^227 mod 437)^308 mod 437 = (7^308 mod 437)^227 mod 437.

To solve for the shared secret key, we first need to calculate (7^308 mod 437). This can be done by raising 7 to the 308th power and then taking the remainder when divided by 437. We can do this by repeatedly squaring 7 and taking the remainder each time. This results in the following sequence:

7^2 mod 437 = 49

7^4 mod 437 = 161

7^8 mod 437 = 267

7^16 mod 437 = 9

7^32 mod 437 = 49

7^64 mod 437 = 161

7^128 mod 437 = 267

7^256 mod 437 = 9

7^512 mod 437 = 49

Since 512 is greater than 308, we can stop here and use the value 49 as the result of 7^308 mod 437. We can now plug this value into the formula to calculate the shared secret key: (49^227 mod 437)^308 mod 437 = (49^308 mod 437)^227 mod 437.

To solve for the shared secret key, we need to find the value of 49^308 mod 437. This can be done using the same method as before, by repeatedly squaring 49 and taking the remainder each time. This results in the following sequence:

49^2 mod 437 = 67

49^4 mod 437 = 382

49^8 mod 437 = 221

49^16 mod 437 = 67

49^32 mod 437 = 382

49^64 mod 437 = 221

49^128 mod 437 = 67

49^256 mod 437 = 382

Since 256 is greater than 308, we can stop here and use the value 382 as the result of 49^308 mod 437. We can now plug this value into the formula to calculate the shared secret key: 382^227 mod 437 = 382^227 mod 437.

To find the shared secret key, we need to calculate 382^227 mod 437. This can be done using the same method as before, by repeatedly squaring 382 and taking the remainder each time. This results in the following sequence:

Therefore the solution to the given matrix problem is  

a)det(B) = det(A) = 3  ,det(B) = 3*det(A) = 9  and c)det(B) = -det(A) = -3

A matrix is a rectangular array or table that contains numbers, symbols, or expressions that are arranged in rows and columns to represent a mathematical object or a characteristic of such an entity.

Here,

The following will be demonstrated using determinant properties:

A)Det(B) = 3

B) Det(B) = 9

C) det(B) = -3

Assuming A is a 4x4 matrix, we can see that:

det(A) = 3.

a) In this case, we are adding one row to another row by performing a transformation to the data in A. These operations don't alter the matrix's determinant, therefore in this instance:

det(B) = 3 = det(A)

b) If K is used to multiply a row of A to produce B, then:

B = det(K*det) (A).

In this situation, we have:

det(A) = 3*det(B) = 9

c) If we switch two rows around once (this is an odd permutation), the determinant's sign changes:

Step-by-step explanation:

1) rewrite the mixed numbers into improper fractions. We do this by multiplying the denominator by the whole number, and then adding the numerator. The numerator stays the same:

[tex]3 \frac{3}{4} = \frac{(4 \times 3) + 3}{4} = \frac{15}{4} [/tex]

[tex]2 \ \frac{2}{7} = \frac{(7 \times 2) + 2}{7} = \frac{16}{7} [/tex]

So the length of the cloth = 15/4 meters

width of the cloth = 16/7 meters

2) Calculate the area of the cloth:

area = length × width

[tex]area \: = \: \frac{15}{4} \times \frac{16}{7} = \frac{240}{28} = \frac{60}{7} (simplest form)[/tex]

area = 60/7 m²

3) The cloth costs $14 per square meter, so the total cost of the cloth is:

the area of the cloth × cost of cloth per square meter

[tex]cost \: = \: \frac{60}{7} \times 14 = \frac{840}{7} = 120[/tex]

the cost is $120

True, the graphical solution method of linear programming employs the corner point method to find the optimal solution.

The most straightforward method of problem optimization is linear programming. We can turn a real-world issue into a mathematical model using this approach. Linear programming can be used to handle a wide range of issues in many different fields, although it is typically applied to issues where the goal is to maximize profit, cut costs, or use resources as sparingly as possible.

Explanation:

The corner point method of graphical linear programming involves plotting the linear equations representing the constraints of the problem onto a graph and then finding the points of intersection of the equations. These points of intersection are called the corner points, and the optimal solution will be located at the corner point that produces the greatest value.

Answer:

Read carefully below

Step-by-step explanation:

We can use spherical coordinates to represent the points on the sphere. These coordinates are typically denoted as (r, θ, φ), where r is the radius of the sphere, θ is the polar angle, and φ is the azimuthal angle.

In order to find a parametric representation of the part of the sphere that lies inside the given cones, we can use the following approach:

First, we need to find the intersection of the sphere and the cone. This is the set of points that satisfy the equations of both the sphere and the cone.

Then, we can use spherical coordinates to represent these points on the sphere.

Finally, we can use these spherical coordinates as parameters in a parametric equation of the form x = x(r, θ, φ), y = y(r, θ, φ), z = z(r, θ, φ) to represent the points on the part of the sphere that lies inside the cone.

Let's use this approach to find a parametric representation of the part of the sphere that lies inside the cone z = 3(x^2 + y^2) in the first case.

To find the intersection of the sphere and the cone, we need to solve the following system of equations:

x^2 + y^2 + z^2 = 16 (equation of the sphere)

z = 3(x^2 + y^2) (equation of the cone)

Substituting the second equation into the first equation, we get:

x^2 + y^2 + 9(x^4 + y^4) = 16

This equation represents an ellipse in the xy-plane. We can use the parametric equations of an ellipse to represent the points on this ellipse:

x = a * cos(t)

y = b * sin(t)

where a and b are the semi-major and semi-minor axes of the ellipse, respectively, and t is a parameter that varies from 0 to 2π.

We can now use spherical coordinates to represent the points on the part of the sphere that lies inside the cone. We can let r be the radius of the sphere (r = 4), θ be the polar angle (0 ≤ θ ≤ π), and φ be the azimuthal angle (0 ≤ φ ≤ 2π).

The parametric equations of the sphere in spherical coordinates are:

x = r * sin(θ) * cos(φ)

y = r * sin(θ) * sin(φ)

z = r * cos(θ)

Substituting the equations for x and y from the ellipse into the equations for x and y from the sphere, we get:

x = 4 * sin(θ) * cos(φ) = a * cos(t)

y = 4 * sin(θ) * sin(φ) = b * sin(t)

z = 4 * cos(θ) = 3(x^2 + y^2) = 3(a^2 * cos^2(t) + b^2 * sin^2(t))

We can solve for a and b in terms of r and θ:

a = 4 * sin(θ)

b = 4 * sin(θ)

Therefore, the parametric equations for the part of the sphere that lies inside the cone z
