Answer:

\(\huge\boxed{\sf Solution\ Set = \{5,-4\}}\)

Step-by-step explanation:

Given equation is:

\(x^2-x-20=0\)

Factoring it by mid-term break method.

+4x × -5x = -20x² (multiplication of side terms)

-5x + 4x = -x (Middle term)

Hence, we can split -x into -5 and +4

\(x^2-5x+4x-20=0\\\\x(x-5)+4(x-5)= 0\\\\Take \ (x-5)\ common\\\\(x-5)(x+4)=0\\\\\)

Either:

x - 5 = 0       OR       x + 4 = 0

x = 5             OR       x = -4

Solution Set = {5,-4}

\(\rule[225]{225}{2}\)

Average waiting time for FCFS: 8.75

Average waiting time for SJF: 4.75

To solve this scheduling problem using FCFS (First-Come, First-Served) and SJF (Shortest Job First) algorithms, let's go step by step:

Schedule order for FCFS:

The FCFS algorithm schedules processes based on their arrival time. So, the schedule order for FCFS is as follows:

Pl -> P2 -> P3 -> P4

Average waiting time for FCFS:

To compute the average waiting time for FCFS, we need to calculate the waiting time for each process and then take the average.

Process | Arrival Time | Running Time | Waiting Time

Pl | 0 | 3 | 0

P2 | 3 | 10 | 3

P3 | 4 | 6 | 13

P4 | 5 | 1 | 19

Average waiting time = (0 + 3 + 13 + 19) / 4 = 8.75

Therefore, the average waiting time for FCFS is 8.75.

Schedule order for SJF:

The SJF algorithm schedules processes based on their running time. The process with the shortest running time gets executed first. If multiple processes have the same running time, the process with the earliest arrival time is selected first. The schedule order for SJF is as follows:

Pl -> P4 -> P3 -> P2

Average waiting time for SJF:

To compute the average waiting time for SJF, we need to calculate the waiting time for each process and then take the average.

Process | Arrival Time | Running Time | Waiting Time

Pl | 0 | 3 | 0

P4 | 5 | 1 | 3

P3 | 4 | 6 | 6

P2 | 3 | 10 | 10

Average waiting time = (0 + 3 + 6 + 10) / 4 = 4.75

Therefore, the average waiting time for SJF is 4.75.

Prove that the equation \(x^5 + 5x + 1 = 0\) has exactly one solution in the interval (-1, 0).

To prove that the equation has exactly one solution in the given interval, we can use the Intermediate Value Theorem. According to this theorem, if a continuous function takes on different signs at two points in an interval, then it must have at least one root (solution) in that interval.

In this case, consider the function f(x) = \(x^5 + 5x + 1\). We can observe that f(-1) = -5 and f(0) = 1. Since f(-1) is negative and f(0) is positive, the function changes sign within the interval (-1, 0). Therefore, by the Intermediate Value Theorem, there must exist at least one root of the equation \(x^5 + 5x + 1 = 0\) in the interval (-1, 0).

To show that there is exactly one solution, we need to establish that the function does not change sign again within the interval. This can be done by analyzing the behavior of the function and its derivative. By studying the derivative, we can confirm that the function is increasing and crosses the x-axis only once in the given interval, ensuring that there is a single solution.

Therefore, we have proven that the equation \(x^5 + 5x + 1 = 0\) has exactly one solution in the interval (-1, 0).

The probability density function (PDF) for a uniform distribution ranging between 2 and 6 is 0.25 i.e., the correct option is D.

In a uniform distribution, all values within the range have an equal probability of occurring. The PDF is used to describe the distribution of probabilities over the range. For a uniform distribution ranging between 2 and 6, the PDF would be a horizontal line with a height of 1/4 (or 0.25) between 2 and 6, and zero outside that range. However, at any specific point within the range, the PDF does not have a defined value.

The reason for this is that the PDF for a continuous random variable in a uniform distribution is defined as a constant value divided by the width of the range. Since the range for this uniform distribution is 4 (from 2 to 6), the constant value would be 1/4.

However, at any specific point within the range, the width of the range becomes zero, resulting in an undefined value for the PDF.

Therefore, the PDF for a uniform distribution ranging between 2 and 6 is indeed 0.25, as it provides a constant probability density over the entire range.

Compared with the standard equation of line y = mx + c,

Slope m = 2/3
Similarly.
The slope of line 2 = -3/2
The slope of line 3 = 2/3

Now. properties of pair of lines state that the slope of parallel lines is equal and the slope of perpendicular lines are negative reciprocal of each other,
So
Slope of line 1 = slope of line 3
But,
The slope of line 2 is the negative reciprocal of the slope of lines 1 and 3.

Yes, it is possible for a plot of a partial expansion of f[x] to share ink with the plot of f[x] all the way from -[infinity] to + [infinity].

Explanation:

We can approximate f(x) as a Fourier series, as follows:

\($$f(x) = \sum_{n=0}^{\infty}a_n\cos\left(\frac{n\pi x}{L}\right)+\sum_{n=1}^{\infty}b_n\sin\left(\frac{n\pi x}{L}\right)$$\)

If f(x) is an odd function, the cosine terms are gone, and if f(x) is an even function, the sine terms are gone.

We can create an approximation for f(x) using only the first n terms of the Fourier series, as follows:

\($$f_n(x) = a_0 + \sum_{n=1}^{n}\left[a_n\cos\left(\frac{n\pi x}{L}\right)+b_n\sin\left(\frac{n\pi x}{L}\right)\right]$$\)

For any continuous function f(x), the Fourier series converges uniformly to f(x) on any finite interval, as given by the Weierstrass approximation theorem.

However, if f(x) is discontinuous, the Fourier series approximation does not converge uniformly.

Instead, it converges in the mean sense or the L2 sense. The L2 norm is defined as follows:

\($$\|f\|^2 = \int_{-L}^{L} |f(x)|^2 dx$$\)

Hence, it is possible for a plot of a partial expansion of f(x) to share ink with the plot of f(x) all the way from -[infinity] to + [infinity].

Step-by-step explanation:

Answer:

a. When x = -1, the value of y = 3

b. When y = 7, the value of x = 1

c. The y-intercept is (0, 5)

d. The x-intercept is (-2.5, 0)

e. The slope of the line is 2

f. The equation of the line is y = 2x + 5

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

The x-intercept is the value of x at y = 0

From the given graph:

a.

∵ x = -1

→ Look at the graph and find the y-coordinate of the point on

   the line whoes x-coordinate = -1

∴ y = 3

∴ When x = -1, the value of y = 3

b.

∵ y = 7

→ Look at the graph and find the x-coordinate of the point on

   the line whose y-coordinate = 7

∴ x = 1

∴ When y = 7, the value of x = 1

c.

∵ The y-intercept of the graph is the point of intersection of

   the graph and the y-axis

→ Look at the graph and find the y-coordinate of the point on

   the line whose x-coordinate = 0

∴ y = 5

∴ The y-intercept is (0, 5)

d.

∵ The x-intercept of the graph is the point of intersection of

   the graph and the x-axis

→ Look at the graph and find the x-coordinate of the point on

   the line whose y-coordinate = 0

∴ x = -2.5

∴ The x-intercept is (-2.5, 0)

e.

∵ The slope of the line m = Δy/Δx

→ Use the intercepts to find it

∵ The intercepts are (-2.5, 0) and (0, 5)

∴ Δx = 0 - (-2.5) = 2.5

∴ Δy = 5 - 0 = 5

∴ m = 5/2.5 = 2

∴ The slope of the line is 2

f.

∵ The form of the equation of the line is y = m x + b

∵ m = 2

∵ b = 5

∴ y = 2x + 5

∴ The equation of the line is y = 2x + 5

The equation of the line is y = 2.27x + 5.

We are given that;

The graph of the line

Now,

a. When x = -1

y= 3

b. When y = 7

x= 1

c. The y-intercept of the graph= 7

d. The x-intercept of the graph= 3.5

The slope of the line can be calculated using the formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0,5) and (x2, y2) = (-2.2,0).

Substituting the values in the formula we get:

slope = (0 - 5) / (-2.2 - 0) = 5 / 2.2 ≈ 2.27

The equation of the line can be found using the slope-intercept form of a line which is given by:

y = mx + b

where m is the slope and b is the y-intercept.

We already know that m ≈ 2.27.

To find b we can use either of the two points. Let (0,5):

y = mx + b 5 = 2.27(0) + b b = 5

Therefore, by the equation answer will be y = 2.27x + 5.

Based on the information provided, it appears that you are examining the data set called "Monarch" from the study by Lunn and McNeil (1991), which contains the years lived after inauguration, election, or coronation of U.S. presidents, popes, and British monarchs from 1690 to a point before Nixon, Carter, and Reagan.

To determine whether the groups (U.S. presidents, popes, and British monarchs) differ in terms of years lived after their respective inaugurations, elections, or coronations, you should perform a statistical test, such as an ANOVA (Analysis of Variance).

Here's a step-by-step guide to perform an ANOVA:

1. Organize the data: Arrange the years lived after inauguration, election, or coronation for each group (U.S. presidents, popes, and British monarchs) in separate columns or lists.

2. Calculate group means: Compute the mean years lived after the event for each group.

3. Perform ANOVA: Conduct an ANOVA test using statistical software or an online calculator by inputting the organized data. The software or calculator will calculate the F-statistic and its associated p-value.

4. Interpret the results: Compare the p-value obtained from the ANOVA test to your chosen significance level (typically 0.05). If the p-value is less than the significance level, you can reject the null hypothesis, which means there is a significant difference between the groups. If the p-value is greater than the significance level, you cannot reject the null hypothesis, indicating that there is no significant difference between the groups.

Remember to include the specific ANOVA results (F-statistic and p-value) in your conclusion.
