By calculation, your grade in the class now is 78.7

From the question, we have the following parameters that can be used in our computation:

Score of 47.2 in 60

Represent the score in 100% with x

So, we have the following equation

47.2/60 = x/100

Multiply both sides of the equation by 100

So, we have

100 * 47.2/60 = x/100 * 100

This gives

100 * 47.2/60 = x

So, we have

x = 100 * 47.2/60

Explanation:

This is a piecewise function. As the name implies, the g(x) is broken up into 3 pieces. Each piece depends on what the input x is.

If x is between \(-\infty\) and \(-7\), excluding both endpoints, then we pick the first piece. So in this case, \(g(x) = x^2-5\)

Or if \(-7 \le x \le 2\), then we go for the second piece and \(g(x) = 9x-17\)

Lastly, if x is between \(2\) and \(\infty\), then we go for the last piece and say \(g(x) = (x+1)(x-5)\)

------------------

To paraphrase that last section, we have g(x) defined as having a split personality or multiple identities depending on what x is.

------------------

The question is: which piece do we pick?

Well, g(7) means that x = 7 for g(x). We'll pick the third piece because 7 is between 2 and infinity. In other words, x = 7 makes \(x > 2\) a true inequality.

So,

\(g(x) = (x+1)(x-5) \ \text{ when } x > 2\\\\g(7) = (7+1)(7-5) \ \text{ replace every x with 7}\\\\g(7) = (8)(2)\\\\g(7) = 16\\\\\)

The number of ways integer points can be assigned to the 12 problems, given that the total points is 100 and each problem is worth at least five points, can be calculated using a combinatorial approach.

To determine the number of ways, we can use the concept of stars and bars, which is a combinatorial technique used to distribute indistinguishable objects into distinguishable groups. In this case, the stars represent the total points (100) and the bars represent the dividers between the problems.

Since each problem is worth at least five points, we can consider a minimum of five points already assigned to each problem. This means we need to distribute the remaining points (100 - 12*5 = 40 points) among the 12 problems.

Using the stars and bars approach, we have 40 stars (representing the remaining points) and 11 bars (representing the dividers between the 12 problems). The number of ways to arrange these stars and bars is equivalent to the number of ways to assign points to the problems.

The answer, therefore, can be calculated using the formula for combinations with repetition: C(n + k - 1, k - 1), where n is the number of stars (40) and k is the number of bars (11).

Hence, the number of ways to assign integer points to the problems is C(40 + 11 - 1, 11 - 1) = C(50, 10).

To find all points with a specific x-coordinate, you need to have the equation of the curve or the data points representing the graph. If you have an equation, you can substitute the desired x-coordinate into the equation and solve for the corresponding y-coordinate.

If you have data points, you can look for the points that have the specified x-coordinate.

For example, let's say you have the equation of a line: y = 2x + 3. If you want to find all points with an x-coordinate of 5, you can substitute x = 5 into the equation to find y. In this case, y = 2(5) + 3 = 13. So the point (5, 13) has an x-coordinate of 5.

The hash table with a size of 11 and the hash function h(x) = 2x mod 11 will be filled with values 65, 75, 68, 26, 59, 31, 41, 73, and 114 in the given order.

After inserting the values, the resulting hash table will have the following elements at each index: Index 0: 114, Index 1: -, Index 2: 65, Index 3: 26, Index 4: 68, Index 5: 75, Index 6: 31, Index 7: 59, Index 8: -, Index 9: 41, and Index 10: 73.

To determine the position of each value in the hash table, we apply the hash function h(x) = 2x mod 11.

For the first value, 65, applying the hash function gives us h(65) = 2 * 65 mod 11 = 9. So we insert 65 at index 9.

Similarly, for the remaining values, we calculate their corresponding positions in the hash table:

- 75: h(75) = 2 * 75 mod 11 = 8 (inserted at index 8)

- 68: h(68) = 2 * 68 mod 11 = 1 (inserted at index 1)

- 26: h(26) = 2 * 26 mod 11 = 3 (inserted at index 3)

- 59: h(59) = 2 * 59 mod 11 = 7 (inserted at index 7)

- 31: h(31) = 2 * 31 mod 11 = 9 (collision with index 9, so we handle collision by chaining or other methods)

- 41: h(41) = 2 * 41 mod 11 = 9 (collision with index 9, so we chain it after 31)

- 73: h(73) = 2 * 73 mod 11 = 10 (inserted at index 10)

- 114: h(114) = 2 * 114 mod 11 = 0 (inserted at index 0)

After inserting all the values, the resulting hash table will have the elements as mentioned . In cases of collision, like the values 31 and 41 both hashing to index 9, we can handle them by chaining the values at the same index.

Answer:

Both questions option d is right

Answer:

See below.

Step-by-step explanation:

Let x represent the number of days.

Since Day and Night Kennel charges a fee of $20 per day and only a one-time fee of $15:

\(y=20x+15\)

Where y represents the total cost, 20x represents the cost for staying x days and 15 is the initial one-time fee.

For Bark Time Hotel, similarly:

\(y=30x+5\)

Again, y represents the total cost, 30x represents the cost for staying x days, and 5 is the initial one-time fee.

Thus, the system of equations is:

\(y=20x+15\\y=30x+5\)

The system that represents this real-world situation is:

Cost = 20d + 15

Cost = 30d + 5

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The system that represents this real-world situation is:

Let d be the number of days the pet will be boarded.

For Day and Night Kennel:

Cost = 20d + 15

For Bark Time Hotel:

Cost = 30d + 5

In this system, d represents the number of days the pet will be boarded, the constant 20 represents the daily boarding fee charged by Day and Night Kennel, the constant 30 represents the daily boarding fee charged by Bark Time Hotel, the constant 15 represents the one-time food fee charged by Day and Night Kennel, and the constant 5 represents the one-time food fee charged by Bark Time Hotel.

Thus,

Cost = 20d + 15

Cost = 30d + 5

The net profit margin for this shirt is 55%.

What is net profit?

Net profit is the amount of money your business earns after deducting all operating, interest and tax expenses over a period of time. To arrive at this value, you need to know the company's gross profit. If the value of net profit is negative, it is called net loss.

Net profit is another important parameter that determines the financial health of your business. It shows whether the company can earn more than it spends. Net profit helps you decide when and how to expand your business and when to cut costs.

It is important for a business owner to know the difference between profit and profitability. Profit is an absolute number equal to revenues minus expenses. Profitability, on the other hand, is a relative number (percentage) that equals the ratio of profit to revenue.

Profitability is a measure of efficiency and is useful in determining the success or failure of a business.

Given,

Revenue = $12

Cost of goods sold = $3

Operating expenses = 20% of revenue = 20/100 x $12 = $2.4

We know,

Net Profit = Revenue - Cost of goods sold - Operating expenses

\(Net \: Profit = 12 - 3 - 2.4\)

Hence, Net Profit = $6.6

Again,

Net Profit Margin = (Net Profit / Revenue) x 100%

Net Profit Margin \(= ( \frac{6.6}{ 12}) \times 100\%\)

SO, Net Profit Margin = 55%

Therefore, the net profit margin for this shirt is 55%.

The equation of the parabola with the given vertex and focus is x^2 = 24y.

What is parabola?

A parabola is a U-shaped curve that is symmetric and can either open upward or downward. It is a conic section and is defined as the locus of points equidistant from a fixed point called the focus and a fixed line called the directrix

To find the equation of a parabola with the vertex at the origin (0, 0) and a focus at (-6, 0), we can use the standard form equation for a horizontally-oriented parabola:

(x - h)^2 = 4p(y - k)

where (h, k) represents the vertex coordinates, and p is the distance between the vertex and the focus.

In this case, the vertex is at (0, 0) and the focus is at (-6, 0). The distance between the vertex and focus is given by p = 6 (since the x-coordinate of the focus is 6 units away from the vertex).

Plugging these values into the standard form equation, we have:

(x - 0)^2 = 4(6)(y - 0)

Simplifying further, we get:

x^2 = 24y

Therefore, the equation of the parabola with the given vertex and focus is x^2 = 24y.

When diameter is 60 mm, the volume increases at a rate of 22,620 mm³/s.

Step 1: Create an equation that connects a sphere's volume to radius as the first step.

V = 4/3*π*r³

Step 2: Calculate each side's derivative in respect to time (Let the time be "t").

(d/dt)V = (d/dt)(4/3*π*r³)

dV/dt = 4πr²*dr/dt

Step 3: The problem description informs us that the diameter is 600 m, hence r must be 30 mm.

Additionally, it is stated that now the radius of a sphere is expanding at a rate of 2 mm/s; as a result, dr/dt must equal 2 mm/s.

We are interested in dV/dt, or the rate of change of the sphere's volume.

dV/dt = 4π(30mm)²*(2mm/s)

dV/dt = 22,620 mm³/s

So, when diameter is 60 mm, the volume increases at a rate of 22,620 mm³/s.

It is recommended that the analyst make advantage of the alpha aesthetic. For the purpose of drawing attention to certain data points, the alpha aesthetic makes some points on a plot more transparent than others.

A scatter plot is a representation of a group of points that is displayed on both a horizontal and a vertical axis. Scatter plots are very important in the field of statistics due to the fact that they may show the degree of correlation, if any, that exists between the values of observed quantities or events (called variables).

Scatter plots are used to indicate the degree to which one variable is impacted by another by plotting data points on a horizontal and vertical axis. This is done in an attempt to show how closely the two variables are related.

The location of the marker that symbolizes each row in the data table is determined by the values that are placed in the columns that are positioned along the X and Y axes.
