The required probability for the three dices to be rolled for the given condition is equal to ,

probability 0.579 when X=0,

probability 0.347 when X =1

probability 0.069 for X = 2

probability 0.005 when X = 3.

The random variable X represents the number of times the number '2' is rolled when three dices are rolled.

X represents the values from 0 (when no '2' is rolled) to 3 (when all three dices show '2'.

Probabilities for each case, use the binomial probability formula, we, have,

P(X = a) =ⁿCₐ × pᵃ × (1-p)ⁿ⁻ᵃ

n = Number of trials (in this case, n = 3)

a = Number of successes (here, 'a' ranges from 0 to 3).

p = Probability of success (rolling a '2' on a single die)

p = 1/6

Required probabilities for each possibility is,

P(X = 0) = (³C₀) × (1/6)^0 × (5/6)^3

             = 125/216

             ≈ 0.579

P(X = 1) = ((³C₁) × (1/6)¹ × (5/6)²  

            = 75/216

            ≈ 0.347

P(X = 2) = ³C₂× (1/6)²× (5/6)¹  

             = 15/216

             ≈ 0.069

P(X = 3) = (³C₃) × (1/6)³× (5/6)⁰

             = 1/216

A linear system with 3 equations and 4 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form can be solved.

A mathematical representation of a system based on the application of a linear operator is known as a "linear system" in systems theory. Ordinarily, compared to nonlinear systems, linear systems display much simpler features and properties. The automatic control theory, signal processing, and telecommunications all heavily rely on linear systems as a mathematical abstraction or idealisation.

Linear systems, for instance, are frequently used to model the propagation medium for wireless communication systems. An operator, H, that converts an input, x(t), into an output, y(t), a kind of black box description, can be used to describe a general deterministic system.

The superposition principle, or alternatively both the additivity and homogeneity properties, must be satisfied by a system to be considered linear, and only then.

(a) The function f(x) = 1/(x - 4) is invertible. (b) The function g(x) = 2x² - 7x + 100 is not invertible. (c) The function h(x) = 7x + 11 is invertible.

To determine if a function is invertible, we need to check if it satisfies the horizontal line test. If every horizontal line intersects the graph of the function at most once, then the function is invertible.

(a) For f(x) = 1/(x - 4), the function is invertible since every horizontal line intersects the graph at most once, except at the vertical asymptote x = 4.

(b) For g(x) = 2x² - 7x + 100, the function is not invertible. It is a quadratic function, and quadratic functions are not invertible because they fail the horizontal line test. There are multiple x-values that correspond to the same y-value, resulting in non-unique inverse values.

(c) For h(x) = 7x + 11, the function is invertible. It represents a linear function, and linear functions pass the horizontal line test since every horizontal line intersects the graph at most once.

True. In the Cobb-Douglas production function, the variables K and L represent the inputs of capital and labor. The exponents β1 and β2 represent the output elasticities with respect to the respective inputs.

The Cobb-Douglas production function is a widely used mathematical representation of production relationships in economics. It assumes a multiplicative relationship between the inputs and the output. In this function, K represents the quantity of capital and L represents the quantity of labor employed in the production process. The exponents β1 and β2 capture the responsiveness of output to changes in the capital and labor inputs, respectively. These exponents are typically positive and reflect the marginal productivity of each input. By adjusting the values of β1 and β2, the production function can represent different levels of substitutability or complementarity between capital and labor. Overall, the Cobb-Douglas function provides a flexible framework to analyze the production process and understand the contributions of capital and labor to output formation.

The Cartesian equation for the particle's path is y = (1/3)(x - 1)^2, representing a parabolic curve. The particle moves in the positive x-direction as t increases.

To find the Cartesian equation, we eliminate the parameter t by isolating t in one of the equations and substituting it into the other equation:

From x = 3t + 1, we can solve for t as t = (x - 1)/3.

Substituting this value of t into y = 9t^2, we get y = 9[(x - 1)/3]^2.

Simplifying the equation, we have y = (3/9)(x - 1)^2, which simplifies further to y = (1/3)(x - 1)^2.

The Cartesian equation for the particle's path is y = (1/3)(x - 1)^2. This equation represents a parabolic curve.

To graph the Cartesian equation, plot the points on the graph where x and y satisfy the equation. The graph will show a parabolic curve. Since the parameter t ranges from negative infinity to positive infinity, the particle's path extends infinitely in both directions.

The direction of motion can be determined by analyzing the coefficient of t in the parametric equation for x. In this case, the coefficient is 3, indicating that as t increases, the particle moves in the positive x-direction.

The plane's genuine speed (ground speed) is around 771.2 km/hr, and its bearing is somewhat toward the east of north.

We must take into account the effect of the wind in order to determine the actual velocity (ground speed) and direction of the airplane.

Given:

The plane's airspeed is 800 km/hr, and the wind speed is 60 km/hr. The wind is blowing in the northwest. First, let's divide the wind into its northward and westward components. Since the breeze is blowing from the northwest, it has both toward the north and toward the west parts.

Trigonometry can be used to calculate the components of the wind. Since the northwest course is 45 degrees among north and west, we can track down the parts as follows:

Wind speed * sin(45°) = 60 km/hr * sin(45°) = 60 km/hr * 2 / 2 = 30 km/hr Wind speed * cos(45°) = 60 km/hr * cos(45°) = 60 km/hr * 2 / 2 = 30 km/hr Now, let's take into account the effects of the wind when calculating the actual velocity (ground speed) and direction of the airplane.

Since the plane requirements to head due north, it should neutralize the toward the west part of the breeze to keep up with its toward the north course.

Genuine speed (ground speed) = Velocity of the plane - Toward the west part of the breeze

= 800 km/hr - 30√2 km/hr

≈ 771.2 km/hr (adjusted to one decimal spot)

The heading of the plane will be somewhat toward the east of north, as it makes up for the toward the west wind part.

Thusly, the plane's genuine speed (ground speed) is around 771.2 km/hr, and its bearing is somewhat toward the east of north.

Answer:

Q2)

We have food for 400 people, and it will last for 23 days.

Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:

23 days = K/400 people.

Then we get:

(23 days)*(400 people) = K = 9200 days*people.

Now if we increase the number of people by 60, we get.

people = 460

Then the number of days that this will last is:

D = (9200 days*people)/460 people = 20 days.

The food will last for 20 days.

Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:

40 = k*200

With this, we can find the value of k

40/200 = k = 0.2

Then the proportional relationship is:

y = 0.2*x

a) We need to replace x by 15.

y = 0.2*15 = 3

y = 3

b) We need to replace y by 8.

8 = 0.2*x

8/0.2 = x = 40

x = 40

Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.

Then we get:

8 = k/30

Then the value of k is:

8*30 = k = 240

then the relationship is:

y = 240/x

a) we need to replace x by 4

y = 240/4 = 60

y = 60

b) we need to replace y by 360

360 = 240/x

360*x = 240

x = 240/360 = 0.666...

x = 0.666...

The difference quotient for the given function is 9 -2/h.

The difference quotient for the given function can be calculated as:

[f(x+h) - f(x)]/h

= [(3(x+h)² - 2(x+h) + 5) - (3x² - 2x + 5)]/h

= (3x² + 6xh + 3h² - 2x - 2h + 5 - 3x² + 2x - 5)/h

= (6xh + 3h² - 2h)/h

= (6x + 3h -2)/h

Simplifying the expression further, we get:

(6x + 3h -2)/h = 6 + 3h/h -2/h

= 6 + 3 -2/h

If the length of a rectangle is nine inches more than its width and its area is 442 square inches, the width of the rectangle is 17 inches and its length is 26 inches.

Let's denote the width of the rectangle as "w" and its length as "l". From the problem statement, we know that:

l = w + 9 (since the length is nine inches more than the width)

The area of the rectangle is given by the formula:

A = l * w

Substituting in the expression for "l" in terms of "w", we get:

A = (w+9) * w

Simplifying, we get a quadratic equation:

w^2 + 9w - 442 = 0

We can solve this equation by factoring or using the quadratic formula. Factoring gives:

(w+26)(w-17) = 0

Therefore, the possible values for "w" are -26 and 17. However, since the width of the rectangle cannot be negative, we can eliminate -26 as a possible value. Thus, the width of the rectangle is 17 inches.

Using the expression for "l" in terms of "w", we can find the length:

l = w + 9 = 17 + 9 = 26 inches

The frontal plane is considered to lie flat on the paper, and the other views are drawn relative to it.

A Multiview drawing is one that depicts two or more perspectives of a three-dimensional object in two dimensions.

In multiview drawings, the usual practice is to consider the frontal plane as lying flat in the paper. The frontal plane is the plane that divides the object into front and back portions, and it is perpendicular to both the horizontal and profile planes.

In a multiview drawing, the object is shown from multiple viewpoints or "views", with each view showing the object as it appears when viewed from a different direction. The frontal view shows the object as it appears when viewed from the front, while the horizontal and profile views show the object as it appears when viewed from above and from the side, respectively.

To create a multiview drawing, the views are arranged so that the frontal view is shown on the bottom of the page, with the horizontal view above it and the profile view to the side. This arrangement is based on the assumption that the object is sitting on a horizontal surface, with the front of the object facing the viewer. By convention, the frontal plane is considered to lie flat on the paper, and the other views are drawn relative to it.

The maximum quantity that can be reached in a quadratic model can be determined by finding the vertex of the quadratic function. In this case, with coefficients of 117t and -22.9906t^2, the maximum quantity can be calculated.

To find the maximum quantity in a quadratic model, we need to locate the vertex of the quadratic function. The vertex is the point where the quadratic curve reaches its maximum or minimum value. In a quadratic equation of the form ax^2 + bx + c, the x-coordinate of the vertex can be found using the formula x = -b / (2a). In this case, the coefficients of the quadratic model are 117t and -22.9906t^2. Since there is no constant term, we can disregard it in this calculation. By substituting the values into the formula, we find that the x-coordinate of the vertex is -117 / (2 * -22.9906) = 2.5415.

To determine the maximum quantity, we need to substitute this value back into the quadratic equation. However, since the problem statement does not provide the complete quadratic equation or the context for the variable t, we cannot calculate the exact maximum quantity. Therefore, the specific value of the maximum quantity cannot be determined without additional information.
