Step-by-step explanation:

Answer:

$3,745

Step-by-step explanation:

First, you have to calculate the price after the discount is applied:

Price of the car: $25,000

Discount: 18%

$25,000*18%= $4,500

$25,000-$4,500= $20,500

Second, you have to calculate the total amount she has to pay including the 7% tax:

$25,000*7%= $1,750

$25,000+$1,750= $26,750

Third, as the statement indicates that Ms. Eve had to put  14% of what she had to pay as down payment, you have to calculate the 14% of $26,750:

$26,750*14%= $3,745

According to this, Ms. Eve has to pay $3,745 for the down payment.

Answer:

Angle of elevation from the duck is \(59.7^{o}\)

Step-by-step explanation:

This description can be represented by the three sides of a triangle and the given angle. Let the angle required be represented by θ. Thus applying the appropriate trigonometric function, we have;

Tan θ = \(\frac{opposite}{adjacent}\)

So that,

Tan θ = \(\frac{12}{7}\)

          = 1.7143

θ = \(Tan^{-1}\) 1.7143

  = 59.7438

θ = \(59.7^{o}\)

The angle of elevation from the duck is determined as \(59.7^{o}\).

Answer:

Multiply -3 by 2.

Multiply x by 2.

Combine like terms.

Subtract 6 from both sides.

Use the quadratic formula to solve for x.

Step-by-step explanation:

Given:

-x (-3 + x )2 = 6

-x (-3 + x )2 = 6

-x (-6 + 2x) = 6

-6x + 2x^2 = 6

2x^2 - 6x - 6 = 6 - 6

2x^2 - 6x - 6 = 0

Multiply -3 by 2.

Multiply x by 2.

Combine like terms.

Subtract 6 from both sides.

Use the quadratic formula to solve for x.

Since 3n² + 6n is both O(n² log n) and Ω(n² log n), we can conclude that it is indeed Θ(n² log n).

To prove that 3n² + 6n is in Θ(n² log n), we need to show both the upper and lower bounds.

First, we will prove the upper bound by showing that 3n² + 6n is O(n² log n). This means we need to find constants c and n₀ such that 3n²+ 6n ≤ c(n² log n) for all n ≥ n₀.

Let's simplify the expression 3n² + 6n:

3n² + 6n ≤ 3n² + 6n² (for n ≥ 1, since n is always positive)

            = 9n²

Now, we can set c = 9 and n₀ = 1. For all n ≥ 1:

3n² + 6n ≤ 9n² (which is the same as c(n²))

           ≤ 9n² log n

Therefore, we have shown that 3n² + 6n is O(n² log n), satisfying the upper bound.

Next, we will prove the lower bound by showing that 3n² + 6n is Ω(n² log n). This means we need to find constants c and n₀ such that 3n²+ 6n ≥ c(n² log n) for all n ≥ n₀.

Let's simplify the expression 3n² + 6n:

3n² + 6n ≥ 3n² (for n ≥ 1, since n is always positive)

            = 3n² log n

Now, we can set c = 3 and n₀ = 1. For all n ≥ 1:

3n² + 6n ≥ 3n² log n (which is the same as c(n² log n))

Therefore, we have shown that 3n² + 6n is Ω(n² log n), satisfying the lower bound.

13/8, 13 to 8, 13:8

Step-by-step explanation:

if they won 50 more than they lost and won a total of 130 games, this means they lost 80 games (130-50=80). we can then write this as 130:80, which simplifies to 13:8

Answer:

The answers are 13/8, 13 to 8, 13:8.

Step-by-step explanation:

Since Frederico's team won 50 more games than they lost, and the won 130 games, then you would subtract the two numbers to find their losses:

130 - 50 = 80

The ratio of there wins to losses is 130 to 80.

Then you need to simplify this answer, which would make the ratio 13 to 8.

Three ways to write this are 13/8, 13 to 8, 13:8.

The area of a circle is 158.3 sq. m.

Consider we need to find the area of the given circle.

The radius of a circle is 7.1 m.

The area of a circle is the place occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the circumference of a circle is called the area of the circle.

The area of the circle is:

\(A = \pi r^{2}\) , where r is the circle's radius.

Putting r = 7.1 , π = 3.14, we get

\(A = 3.14 *(7.1)^{2}\)

A = 158.2874

A ≈ 158.3

So, the area of a circle is 158.3 sq. m.

Answer: The scale factor of this dilation is 4/6, or 2/3.

Step-by-step explanation:

The scale factor of a dilation is the ratio of the distances of the corresponding points after the dilation to the distances of the corresponding points before the dilation.

In this case, the distance between A and A' is 4 units (6-2=4). The distance between A and the origin (0,0) is 6 units.

Therefore, the scale factor of this dilation is 4/6, or 2/3.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

The process of evaluating a function is typically straightforward when we have the function in the form of a formula. For instance, it is possible to evaluate the function f(x)=53x2 by first squaring the input number, multiplying by 3, and then subtracting the result from 5.

The algebraic expression should often take one of the following forms: addition, subtraction, multiplication, or division. Bring the variable to the left and the remaining values to the right to determine the value of x.

To determine the outcome, simplify the values. The abscissa is the x value of the point (x, y). It shows how far a point is from the origin or from the x-axis' horizontal axis.

Answer:

Answer:

t/n = 5

Step-by-step explanation:

Now:

Let t = Tom's age now.

Let s = sum of children's ages now.

n years ago:

Tom's age = t - n

Each of the three children was n years younger, so the sum of their ages n years ago is s - 3n

t = s

t - n = 2(s - 3n)

t = s

t - n = 2(t - 3n)

t = s

t - n = 2t - 6n

t = s

-t = -5n

-t/n = -5

t/n = 5

Declaring instance variables as B. private is known as data hiding or information hiding.

In object-oriented programming, the visibility or accessibility of variables and methods is controlled by access modifiers. By declaring instance variables as private,

we restrict their access to within the class itself. This means that the variables cannot be accessed or modified directly from outside the class, including from other classes or objects.

Data hiding, or information hiding, is an important concept in object-oriented programming. It helps encpsulate the internal implementation details of a class, providing a level of abstraction and protecting the data from unintended modification or access.

By declaring instance variables as private, we enforce encapsulation and ensure that the variables can only be accessed and manipulated through public methods or interfaces defined by the class.

Using private instance variables promotes better software design, as it allows for better control over the state of an object and reduces dependencies on its internal structure.

It also provides a way to protect sensitive or critical data within an object, enhancing security and preventing unauthorized access.

The process described above satisfies the Markov property because the future state of the system only depends on the current state, and not on any previous states. The transition probability matrix is P =\(\left[\begin{array}{cccc}0&1&0&0\\1/2&0&1/2&0\\0&1/2&0&1/2\\0&0&1&0\end{array}\right]\)  

In other words, given the current state, the probability distribution of the next state depends only on the current state and not on any previous history.

Let Xn denote the state of the system after the nth step, where Xn = i means that the first urn contains i white balls and 3-i black balls. Since each step involves drawing one ball from each urn and switching them, the number of white balls in the first urn can only change by one after each step. Thus, the only possible transitions are:

If Xn = 0, then the next state Xn+1 can only be 1, with probability 1, since there is only one white ball in the first urn.

If Xn = 1, then the next state Xn+1 can be either 0 or 2, each with probability 1/2, since there are two white balls in the first urn and each ball is equally likely to be drawn.

If Xn = 2, then the next state Xn+1 can be either 1 or 3, each with probability 1/2, since there are two black balls in the first urn and each ball is equally likely to be drawn.

If Xn = 3, then the next state Xn+1 can only be 2, with probability 1, since there is only one black ball in the first urn.

Therefore, the transition probability matrix is:

P =\(\left[\begin{array}{cccc}0&1&0&0\\1/2&0&1/2&0\\0&1/2&0&1/2\\0&0&1&0\end{array}\right]\)  

where Pij is the probability of transitioning from state i to state j. For example, P12 = 1/2 means that the probability of transitioning from state 1 (one white ball in the first urn) to state 2 (two white balls in the first urn) is 1/2.

Correct Question :

Three white balls and three black balls are distributed in two urns in such a way that each contain three balls. We say that the system is in state i, i=0,1,2,3, if the first urn contains i white balls. At each step, we draw one ball from each urn and place the ball drawn from the first urn into the second, and conversely with the ball from the second urn. Let Xn denote the state of the system after the nth step. Explain why Xn = 0, 1, 2, ......... is a Markov chain and calculate its transition probability matrix.
