Hope this helps:)

Answer:

9w² - 18w

or

9w(w - 9)

Step-by-step explanation:

Let's start by applying the distributive property to all of the expressions:

5w(2w - 7) + w(3w + 8) - 4w² + 9w

10w² - 35w + 3w² + 8w - 4w² + 9w

Now, combine the like terms:

9w² - 18w

You could stop there, but if you wanted to, you could factor out a 9 and a w:

9w(w - 9)

Each individual result of a probability experiment is called an "outcome" (d).

An outcome refers to a specific result or occurrence that can happen when conducting a probability experiment. It represents the different possibilities or potential results of an experiment.

For example, when flipping a fair coin, the possible outcomes are "heads" or "tails." In this case, "heads" and "tails" are the two distinct outcomes of the experiment.

Similarly, when rolling a fair six-sided die, the possible outcomes are the numbers 1, 2, 3, 4, 5, or 6. Each number represents a different outcome that can occur when rolling the die.

In summary, an outcome is a specific result or occurrence that can happen during a probability experiment. It is essential to understand outcomes as they form the basis for calculating probabilities and analyzing the likelihood of different events occurring.

Thus, each individual result of a probability experiment is called an "outcome" (d).

Answer:

The number of beads Emery uses to calculate how many 4 necklaces and 7 bracelets are 152 beads.

Step-by-step explanation:

This is a simultaneous equation.

let's make n the number of necklaces, and b the number of bracelets.

8n + 3b = 172. 1st equation

1n + 5b = 77. 2nd equation.

you have to make one of the Bs or the Ns the same.

I chose B. it doesn't matter which side you choose.

40n + 15b =860. I multiplied by 5

3n + 15b =231. I multiplied by 3

then you subtract. because the signs are the same.

40n - 3n = 37n, 15n - 15n = 0, 860 - 231 = 629

37n =629. we divide both sides by 37

n = 17. one necklace has a total of 17 beads.

we substitute to find the number of bracelets (b).

choose any of the 1st or 2nd equations.

1n + 5b = 77

(17) + 5b = 77

5b = 77- 17

5b = 60

b = 12. one bracelet has a total of 12 beads.

NOW: find how many beads Emery uses to calculate how many 4 necklaces and 7 bracelets.

equation: 4n + 7b = ?

4(17) + 7(12) = 152

which means there are 152 beads.

The completed statements with regards to the compound interest of the amount in the account are;

If the account has a 5% interest rate and is compounded monthly, you have $101.655 million money after 2 years

If the account has a 5% interest rate compounded continuously, you would have $106.096 million money after 2 years

Compound interest is the interest calculated based on the initial amount and the accumulated interests accrued from the periods before the present.

The compound interest formula indicates that we get;

\(A = P\cdot (1 + \frac{r}{n}) ^{n\cdot t}\)

Where;

P = The principal amount invested = $92 million

r = The interest rate = 5% monthly

n = The number of times the interest is compounded per annum = 12

t = The number of years = 2 years

Therefore; \(A = 92\cdot (1 + \frac{0.05}{12}) ^{12\times 2}\approx 101.655\)

The amount in the account after 2 years is therefore about $101.655 million

The formula for the amount in the account if the principal is compounded continuously, we get;

A = \(P\cdot e^{(r\cdot t)}\)

Therefore, we get;

\(A = 96 \times e^{0.05 \times 2} \approx 106.096\)

The amount in the account after 2 years, compounded continuously therefore, is about $106.096 million

Organizational culture is defined as the common beliefs, values, attitudes, customs, behaviors, and traditions that characterize a specific organization and determine the manner in which it functions. Organizational culture is set by the manager.

In a corporate or business environment, organizational culture can influence the daily operations of employees. It is the responsibility of managers to create a positive culture that emphasizes teamwork, respect, integrity, and accountability. The manager is an essential individual responsible for establishing and maintaining the organization's culture, which will ultimately define the employee's attitudes, behaviors, and productivity levels. He or she sets the tone for the workplace by creating an environment that fosters collaboration, innovation, and success. Employees need to feel connected to their workplace and colleagues to be motivated to do their best work. If a manager promotes a culture of fear, competition, or dishonesty, employees may become unmotivated or unproductive. An effective manager understands the importance of creating a positive workplace culture and works hard to establish and maintain it. Managers can establish a positive culture by encouraging open communication, providing regular feedback and recognition, fostering a sense of teamwork, creating opportunities for professional development, and setting high standards for performance. Managers must lead by example and demonstrate the behaviors and attitudes that they expect from their employees. They must hold themselves and others accountable for their actions, communicate expectations clearly, and provide support when needed. A positive organizational culture will enable an organization to attract and retain top talent, increase employee engagement, and promote collaboration and innovation.

100 same-day tickets were sold for the cost using equation.

To solve this problem, we can use a system of two equations with two variables. Let x be the number of advance tickets sold and y be the number of same-day tickets sold. Then we have:

x + y = 600   (equation 1: total number of tickets sold)
50x + 30y = 28000   (equation 2: total amount paid for tickets)

We can solve for x and y by using elimination or substitution. Here's one way to do it using substitution:
From equation 1, we have y = 600 - x. Substitute this into equation 2:

50x + 30(600 - x) = 28000

Simplify and solve for x:
50x + 18000 - 30x = 28000
20x = 10000
x = 500

So 500 advance tickets were sold. To find the number of same-day tickets, we can substitute x = 500 into equation 1:

500 + y = 600
y = 100

So 100 same-day tickets were sold.

We can observe that ET is the permutation matrix that reverses the permutation of columns performed by E.

Firstly, to generate the permutation matrix E defined in (2), we need to enter the commands provided in the example. This can be done in MATLAB by simply copying and pasting the commands into the command window.

Once we have the permutation matrix E, we can generate a 5 x 5 matrix A with integer entries using the command A = floor(10*rand(5)). This command generates a matrix A with random integers between 0 and 10.

Next, we need to compute the product EA and compare the answer with the matrix A. The product EA is computed in MATLAB by typing E*A. The resulting matrix is related to A by a permutation of its rows. Specifically, the rows of A are rearranged according to the permutation matrix E.

Left multiplication by the permutation matrix E has the effect of permuting the rows of the matrix A. Specifically, the ith row of A is replaced by the row of A corresponding to the ith row of E.

Similarly, we can compute the product AE and compare the answer with the matrix A. The product AE is computed in MATLAB by typing A*E. The resulting matrix is related to A by a permutation of its columns. Specifically, the columns of A are rearranged according to the permutation matrix E.

Right multiplication by the permutation matrix E has the effect of permuting the columns of the matrix A. Specifically, the ith column of A is replaced by the column of A corresponding to the ith column of E.

Moving on to part (b) of the question, we need to compute E-1 and ET. The inverse of the permutation matrix E can be computed in MATLAB using the command inv(E). The transpose of the permutation matrix E can be computed using the command E'.

Observing E-1 and ET, we can see that they are also permutation matrices. This is because the inverse of a permutation matrix is also a permutation matrix, and the transpose of a permutation matrix is also a permutation matrix.

Furthermore, we can observe that E-1 is the permutation matrix that reverses the permutation of rows performed by E. Specifically, the ith row of A is replaced by the row of A corresponding to the ith row of E-1.

Similarly, we can observe that ET is the permutation matrix that reverses the permutation of columns performed by E. Specifically, the ith column of A is replaced by the column of A corresponding to the ith column of ET.

Overall, we can conclude that permutation matrices are a powerful tool in linear algebra, allowing us to manipulate the rows and columns of a matrix in a precise and structured manner.

The sample proportion is 0.530 and the z-critical value is 2.58 and the confidence interval at 99% is ( 0.503, 0.556 ).

Given that,

Because watching TV via digital streaming is becoming more and more common, tv advertising companies are having a harder time connecting with viewers. 53% of the 2343 American adults surveyed by the Harris Poll on November 13, 2012, claimed they had viewed digitally streamed television content on at least one device.

We have to find what is the sample proportion? firstly, the z-critical value is ? What is the confidence interval at 99%?

We know that,

n = 2343

Point estimate = sample proportion = \(\hat p\) = 0.530

1 - \(\hat p\) = 1 -0.530 = 0.470

At 99% confidence level

α = 1-0.99% =1-0.99 =0.01

α /2 =0.01/ 2= 0.005

Z(α /2) = Z0.005 = 2.576

Z (α/2) = 2.576 = 2.58

Margin of error = E = Z (α/2) × √((\(\hat p\) × (1 - \(\hat p\) )) / n)

=2.576 × (√(0.530×(0.470) /2343 )

= 0.027

A 99% confidence interval for population proportion p is ,

\(\hat p\)- E < p < \(\hat p\) + E

0.530 -0.027 < p < 0.530 +0.027

0.503 < p < 0.556

( 0.503, 0.556 )

m = (3-3)/(2-10)

m = 0/(-8)

m = 0

The slope of any horizontal line is always zero due to the fact all y coordinates on this line are the same. When we pick two points from the line, the same y coordinates subtract to 0. We can have 0 in the numerator, but not in the denominator.

As the slope formula shows, we basically subtract the y coordinates together, and do the same for the x coordinates as well in the same order. Then we divide the differences.
