Zaboca Printing Limited (ZPL) has only one working printer. Eight (8) customers submitted their orders today Monday 6th June 2022. The schedule of delivery of these orders are as follows:
Jobs (in order of arrival) Processing Time (Days) Date Due
A 4 Monday 13th June 2022
B 10 Monday 20th June 2022
C 7 Friday 17th June 2022
D 2 Friday 10th June 2022
E 5 Wednesday 15th June 2022
F 3 Tuesday 14th June 2022
G 8 Thursday 16th June 2022
H 9 Saturday 18th June 2022
All jobs require the use of the only printer available; You must decide on the processing sequence for the eight (8) orders. The evaluation criterion is minimum flow time.
i. FCFS
ii. SOT
iii. EDD
iv. CR
v. From the list (i to iv above) recommend the best rule to sequence the jobs
The recommended rule to sequence the jobs for minimum flow time is the EDD (Earliest Due Date) rule.
The EDD rule prioritizes jobs based on their due dates, where jobs with earlier due dates are given higher priority. By sequencing the jobs in order of their due dates, the goal is to minimize the total flow time, which is the sum of the time it takes to complete each job.
In this case, applying the EDD rule, the sequence of jobs would be as follows:
D (Due on Friday 10th June)
F (Due on Tuesday 14th June)
E (Due on Wednesday 15th June)
C (Due on Friday 17th June)
G (Due on Thursday 16th June)
H (Due on Saturday 18th June)
A (Due on Monday 13th June)
B (Due on Monday 20th June)
By following the EDD rule, we aim to complete the jobs with earlier due dates first, minimizing the flow time and ensuring timely delivery of the orders.
Therefore, the recommended rule for sequencing the jobs in this scenario is the EDD (Earliest Due Date) rule.

First, decide whether the distribution is a discrete probability distribution, then select the reason for making this decision.
The distribution is a discrete probability distribution because the sum equals 1.
To determine whether or not the distribution is a discrete probability distribution, we need to check if the probabilities sum up to 1 and if all the probabilities are non-negative for every possible value of X. Also, the values of X must be countable.
Here, the given table represents the probability distribution of a discrete random variable X. Therefore, it is a discrete probability distribution.
The sum of probabilities is:
P(X = −1) + P(X = 3) + P(X = 5) = 0.05 + 0.38 + 0.57 = 1
and all the probabilities are non-negative.
Therefore, the distribution is a discrete probability distribution.

$$\renewcommand{\arraystretch}{1.5} \begin{pmatrix} -\frac{\sqrt{2}}{2} \frac{1}{n} \\ \frac{\sqrt{2}}{2} \frac{1}{n} \end{pmatrix}$$is a column matrix that contains integers,
we can write it as follows. $$\begin{pmatrix} -\frac{\sqrt{2}}{2} \frac{1}{n} \\ \frac{\sqrt{2}}{2} \frac{1}{n} \end{pmatrix} = \begin{pmatrix} -\frac{1}{\sqrt{2}} \\ \frac{1}{\sqrt{2}} \end{pmatrix} \frac{1}{n}.$$Since n has to be an integer, we have to find the smallest positive integer n for which the right-hand side is a column matrix containing integers. Since the left-hand side has a factor of 1/n, we can see that the smallest value of n must be a divisor of the denominator of the left-hand side. The denominator of the left-hand side is $\sqrt{2}/2$. If we multiply this by 100, we get 70.710678.
Therefore, the smallest positive integer n that satisfies the equation is the smallest divisor of 70.710678. This is 2, and it gives us the column matrix $$\begin{pmatrix} -\frac{1}{\sqrt{2}} \\ \frac{1}{\sqrt{2}} \end{pmatrix}.$$Therefore, the smallest positive integer n is 2.

If the complement of an angle is one-third of its supplement, find the angle
Answer: 45°
Step-by-step explanation:
Let the angle be x and its complement be y
Also,
Complement = 1/3 × Supplement
So,
Supplement = 3 × Complement
= 3y
According to Question:
I. x + y = 90° -----(1)
II. x + 3y = 180° -----(2)
On subtracting eq (1) from (2) we get
2y=90°
y=45°
Now, From eq (1)
x + y = 90°
x = 90° - 45°
x = 45°
∴ The angle is 45°

Step-by-step explanation:
What does it mean for an event to be unusual? why should the cutoff for identifying unusual events not always be 0. 05?.
An unusual event is an occurrence that has a low probability of happening. The cutoff for identifying unusual events not always be 0.05, because it is not always a good idea to utilize the same cutoff to spot unexpected occurrences.
What is an unusual event?An unusual event is an occurrence that has a low probability of happening.
If an event is improbable, its likelihood is zero. If an occurrence is unavoidable, its probability is one.
The probability of an event happening increases as it gets closer to 1. An occurrence that has a probability of 0.375, for instance, is more likely to happen than one with a probability of 0.125.
The less likely an event is to occur, the closer the probability is to 0. An unusual event is what this kind of event falls under. A probability of 5%, or 0.05, is typically regarded as unusual event.

If P=(-2, 5) and Q=(1,9) are the endpoints of the diameter of a circle find the equation of the circle
If \(P=(-2, 5)\) and \(Q=(1,9)\)are the endpoints of the diameter of a circle, the equation of the circle is \((x + 1/2)^2 + (y - 7)^2 = 25/4.\)
To find the equation of the circle with endpoints \(P=(-2, 5)\) and \(Q=(1, 9)\), we can use the midpoint formula and the distance formula.
First, we find the midpoint of the diameter using the midpoint formula:
\(Midpoint = ( (x1 + x2) / 2, (y1 + y2) / 2 )\)
\(= ( (-2 + 1) / 2, (5 + 9) / 2 )\)
\(= ( -1/2, 14/2 )\)
\(= ( -1/2, 7 )\)
Next, we find the radius of the circle by calculating the distance between the midpoint and one of the endpoints using the distance formula:
\(Distance = \sqrt( (x2 - x1)^2 + (y2 - y1)^2 )\)
\(= \sqrt( (1 - (-1/2))^2 + (9 - 7)^2 )\)
\(= \sqrt( (3/2)^2 + 2^2 )\)
\(= \sqrt( 9/4 + 4 )\)
\(= \sqrt( 25/4 )\)
\(= 5/2\)
Now that we have the midpoint\((-1/2, 7)\)and the radius \(5/2\), we can write the equation of the circle in the standard form:
\((x - h)^2 + (y - k)^2 = r^2\)
\((x + 1/2)^2 + (y - 7)^2 = (5/2)^2\)
Thus, the equation of the circle is \((x + 1/2)^2 + (y - 7)^2 = 25/4.\)

The equation of the circle is \(\( (x + 0.5)^2 + (y - 7)^2 = 25 \)\).
To find the equation of the circle with endpoints \(P=(-2, 5)\) and \(Q=(1, 9)\) as the endpoints of the diameter, we can first find the center of the circle.
The center of the circle is the midpoint of the diameter, which can be calculated as:
\(\[ \left(\frac{{x_1 + x_2}}{2}, \frac{{y_1 + y_2}}{2}\right) \]\)
Substituting the given coordinates:
\(\[ \left(\frac{{-2 + 1}}{2}, \frac{{5 + 9}}{2}\right) = (-0.5, 7) \]\)
So, the center of the circle is \((-0.5, 7)\).
Next, we need to find the radius of the circle, which is half the length of the diameter. The radius can be calculated using the distance formula:
\(\[ r = \sqrt{{(x_2 - x_1)^2 + (y_2 - y_1)^2}} \]\)
Substituting the given coordinates:
\(\[ r = \sqrt{{(1 - (-2))^2 + (9 - 5)^2}} = \sqrt{{3^2 + 4^2}} = \sqrt{{9 + 16}} = \sqrt{{25}} = 5 \]\)
Therefore, the equation of the circle is:
\(\[ (x + 0.5)^2 + (y - 7)^2 = 5^2 \]\)
In simplified form:
\(\[ (x + 0.5)^2 + (y - 7)^2 = 25 \]\)
Thus, the equation of the circle is \(\( (x + 0.5)^2 + (y - 7)^2 = 25 \)\).

Economic growth typically results in rising standards of living and prosperity. However, it also invites negative externalities such as environmental degradation due to over- exploiting of natural resources. As such, the world is confronted with the dilemma of growth versus environmental sustainability. Developing a model explaining the disparity of economic development concentrating on drivers such as tourism sustainability, technological innovation and the quality of leadership would be important not only to facilitate future economic growth in developing countries, but also to the environmental and sociocultural sustainability which ultimately lead to global sustainable development. The present research objective is to develop and test framework of sustainable development by considering the elements of tourism, technological innovation, and national leadership. This further would facilitate growth, environmental and socio-cultural sustainability. Understanding the integration of these dimensions would enable the building of a Sustainable Development Framework (SDF) that would provide better insight in promoting the SDGS agenda. Ultimately, growth and environmental sustainability can be achieved which will benefit the society, the economy, and nations and of course for future sustainable policy recommendation. Based on the issue above, you are required to propose relevant econometric approaches with the aims to test sustainable development by considering the elements of tourism, technological innovation, and national leadership. Question 1 [10 marks] [CLO2] Based on the scenario above, a. Propose an appropriate model specification based on the scenario above. [4 marks] used in the [4 marks] [2 marks] b. Justify the selection of the dependent and independent variables model. c. Justify the selection of the sample period.
According to the given information, the sample period should be from 2010-2020.
a) Model specification
The model specification based on the scenario above is as follows:
SDF= f(T, TI, NL)
Where: SDF= Sustainable Development Framework
T= Tourism
TI= Technological innovation
NL= National leadership
b) Justification for the selection of the dependent and independent variables model:
Dependent variable: The dependent variable in this model is Sustainable Development Framework (SDF). The model seeks to develop a framework for sustainable development that would facilitate growth, environmental and socio-cultural sustainability.
Independent variables:
The independent variables are tourism sustainability, technological innovation, and quality of leadership. These variables drive economic development. The inclusion of tourism sustainability reflects its importance in the global economy and its potential to drive growth.
The inclusion of technological innovation reflects its potential to enhance productivity and create new industries. The inclusion of national leadership reflects the role of governance in promoting sustainable development and managing negative externalities.
c) Justification for the selection of the sample period:
The sample period should be selected based on the availability of data for the variables of interest. Ideally, the period should be long enough to capture trends and patterns in the data. However, it should not be too long that the data becomes obsolete or no longer relevant.
Additionally, the period should also reflect the context and relevance of the research question. Therefore, the sample period for this study should cover the last decade to capture the trends and patterns in the data and reflect the relevance of the research question.
The sample period should be from 2010-2020.

The reference angle will be:
\(259-180=79\)Quadrant I : 79°
Quadrant II:
\(180-79=101\)Quadrant III: 259°
Quadrant IV:
\(360-79=281\degree\)3. Find the equation of a line passing through (5,-6) parallel to : x + 3y = 8
The general slope intercept form is : y = m * x + b
Where m is the slope and b is y - intercept
Given the equation of the line : x + 3y = 8
Write the equation in slope intercept form to find the slope of the line
so, solve for y :
\(\begin{gathered} x+3y=8 \\ 3y=-x+8 \\ \\ y=-\frac{1}{3}x+\frac{8}{3} \end{gathered}\)So, the slope of the given line = -1/3
The parallel lines have the same slope
so, the slope of the required line = -1/3
And the equation will be :
\(y=-\frac{1}{3}x+b\)Find the value of b using the given point ( 5 , -6 )
When x = 5 , y = -6
\(\begin{gathered} -6=-\frac{1}{3}\cdot5+b \\ -6=-\frac{5}{3}+b \\ -6+\frac{5}{3}=b \\ \\ b=-\frac{13}{3} \end{gathered}\)So, the equation of the line will be :
\(y=-\frac{1}{3}x-\frac{13}{3}\)it can be written as : 3y = -x - 13
\(x+3y=-13\)
