Answer:

Let's assume the width of the door is x inches. Then, according to the problem, the length of the door is 48 inches longer than the width, which means the length is x+48 inches.

The area of the door is given as 3024 square inches, so we can set up an equation:

Area = width x length

3024 = x(x+48)

Simplifying the equation, we get:

x^2 + 48x - 3024 = 0

Now we can solve for x using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

where a = 1, b = 48, and c = -3024

x = (-48 ± √(48^2 - 4(1)(-3024))) / 2(1)

x = (-48 ± √(2304 + 12096)) / 2

x = (-48 ± √14400) / 2

We take the positive root since the width of a door cannot be negative:

x = (-48 + 120) / 2

x = 36

Therefore, the width of the door is 36 inches.

In perimeter, The cost to frame Joy's math certificate in a fancy frame is $138.00.

The dimensions of Joy's math certificate are 10 inches tall and 13 inches wide.

Joy wants to frame it in a fancy frame that costs $3.00 per inch.

To determine the total cost of framing the certificate, we need to find its perimeter and then multiply that by the cost per inch.

The perimeter of the certificate is:

Perimeter = 2 × (height + width)

Substituting the given values, we get:

Perimeter = 2 × (10 + 13)Perimeter = 46 inches

Therefore, the total cost of framing Joy's math certificate is:

Total cost = Perimeter × Cost per inch

Total cost = 46 × 3.00Total cost = $138.00

The base 16 is the same as 4*4.

From there, the rule \((a*b)^c = a^c*b^c\) is used to get \((4*4)^{1/2} = 4^{1/2}*4^{1/2}\)

Afterward, the exponents are added getting 1/2+1/2 = 2/2 = 1. The rule is \(a^b*a^c = a^{b+c}\) which only works if the bases are both the same.

The point estimator for the proportion of registered voters expressed concern about a loosening of restrictions is 0.58. The margin of error for this poll is 3.6%.

The point estimator for the proportion of registered voters expressing concern about a loosening of restrictions is:

58/100 = 0.58 or 58%

To determine the margin of error for this poll assuming a confidence level of 95%, we can use the following formula:

margin of error = zsqrt(p(1-p)/n)

where z is the z-score for the desired confidence level (1.96 for 95%), p is the point estimator for the proportion (0.58), and n is the sample size (900).

So, the margin of error is:

1.96sqrt(0.58(1-0.58)/900) ≈ 0.036 or 3.6%

(a) The game tree for n = 4 cards can be represented as follows:

     1   3  4   5

    /     |     \

  Bob     |     Dave

  / \     |     / \

 3   4    5    1   3

b here is a bijection between the set of valid games for n cards and a particular subset of subgraphs of K4.n.

In this game tree, each level represents a player's turn, starting with Alice at the top. The numbers on the edges represent the cards played by each player. At each level, the player has multiple choices depending on the available cards. The game tree branches out as each player makes their move, and the game continues until all cards have been played or no valid moves are left.

(b) To prove the bijection between the set of valid games for n cards and a subset of subgraphs of K4.n, we can associate each player's move in the game with an edge in the bipartite graph. Let's consider a specific example with n = 4.

In the game, each player chooses a card from their hand that hasn't been played before. We can represent this choice by connecting the corresponding vertices of the bipartite graph. For example, if Alice plays card 2, we draw an edge between the vertex representing Alice and the vertex representing card 2. Similarly, Bob's move connects his vertex to the chosen card, and so on.

By following this process for each player's move, we create a subgraph of K4.n that represents a valid game. The set of all possible valid games for n cards corresponds to a subset of subgraphs of K4.n.

Therefore, there is a bijection between the set of valid games for n cards and a particular subset of subgraphs of K4.n.

The probability of selecting a defective bulb is 0.16.

Given: 8 Bulbs are defective out of 50 bulbs. To find the probability that a randomly selected item is defective.

What is probability?

Probability shows the possibility of how likely an event is happening to occur out of all the possibilities.

Let’s solve the problem:

Total number of video recorders: 50

The sample space n(S) = 50

Number of defective bulbs: 8

Let E be the event of selecting a defective bulb.

Then n(E) = 8

Therefore, the probability of selecting a defective bulb: Number of defective bulbs / Total number of bulbs

=> n(E) / n(S)

=> 8 / 50

=> 0.16

Thus, we can write that the value of λ=3 is an eigenvalue of the given matrix A and the corresponding eigenvector is v=[-2 5 1]T.

Given matrix is:\($$A = \begin {bmatrix} 2 & 0 & -1 \\ 2 & 2 & 3 \\ -4 & 3 & -4 \end {bmatrix}$$\)Now, to check whether λ = 3 is an eigenvalue of the given matrix A, we will find the determinant of the matrix (A - λI), where I is the identity matrix. If the determinant is zero, then λ is an eigenvalue of the matrix A. The matrix (A - λI) is\(:$$\ {bmatrix} 2 - 3 & 0 & -1 \\ 2 & 2 - 3 & 3 \\ -4 & 3 & -\)end {bmatrix}$$Now, finding the determinant of the above matrix using the cofactor expansion along the first row:$${\begin{aligned}\det(A-\lambda I)&=-1\cdot \begin{vmatrix} -1 & 3 \\ 3 & -7 \end{vmatrix}-0\cdot \begin{vmatrix} 2 & 3 \\ 3 & -7 \end{vmatrix}-1\cdot \begin{vmatrix} 2 & -1 \\ 3 & 3 \end{vmatrix}\\&=-1((1\cdot -7)-(3\cdot 3))-1((2\cdot 3)-(3\cdot -7))\\&=49\end{aligned}}$$Since the determinant is non-zero, hence λ = 3 is an eigenvalue of the matrix A.

Now, to find the corresponding eigenvector, we will solve the equation (A - λI)v = 0, where v is the eigenvector and 0 is the zero vector. The equation becomes:\($$\begin{bmatrix} -1 & 0 & -1 \\ 2 & -1 & 3 \\ -4 & 3 & -7 \end{bmatrix}\begin{bmatrix} x \\ y \\ z \end{bmatrix} = \begin{bmatrix} 0 \\ 0 \\ 0 \end{bmatrix}$$$$\Rightarrow -x - z = 0$$$$2x - y + 3z = 0$$$$-4x + 3y - 7z = 0$$\)Solving the above system of equations using substitution method, we get y = 5z and x = -2z. Taking z = 1, we get the eigenvector as\(:$$v = \begin{bmatrix} -2 \\ 5 \\ 1 \end{bmatrix}$$\)Therefore, λ = 3 is an eigenvalue of the given matrix A and the corresponding eigenvector is v = [-2 5 1]T.

Trent will need a total of 100 star stickers to line both the top and bottom edges of his 0.75-meter-long poster, with each sticker being 15 millimeters wide.

To find out how many star stickers Trent needs for his poster, you should first convert the length of the poster and the width of the stickers to the same unit, either meters or millimeters.

Step 1: Convert the length of the poster to millimeters (1 meter = 1000 millimeters)
0.75 meters * 1000 = 750 millimeters

Step 2: Divide the length of the poster by the width of a star sticker
750 millimeters / 15 millimeters = 50 stickers

Step 3: Since there are two edges (top and bottom) of the poster, multiply the number of stickers needed for one edge by 2
50 stickers * 2 = 100 stickers
