Create a query that lists the total outstanding balances for students on a payment plan and for those students that are not on a payment plan. Show in the query results only the sum of the balance due, grouped by PaymentPian. Name the summation column Balances. Run the query, resize all columns in the datasheet to their best fit, save the query as TotaiBalancesByPian, and then close it.
A query has been created that lists the total outstanding balances for students on a payment plan and for those students that are not on a payment plan.
In order to list the total outstanding balances for students on a payment plan and for those students that are not on a payment plan, a query must be created in the database management system. Below are the steps that need to be followed in order to achieve the required output:
Open the Microsoft Access and select the desired database. Go to the create tab and select the Query Design option.A new window named Show Table will appear.
From the window select the tables that need to be used in the query, here Student and PaymentPlan tables are selected.Select the desired fields from each table, here we need StudentID, PaymentPlan, and BalanceDue from the Student table and StudentID, PaymentPlan from PaymentPlan table.Drag and drop the desired fields to the Query Design grid.
Now comes the main part of the query that is grouping. Here we need to group the total outstanding balances of students who are on a payment plan and who are not on a payment plan. We will group the data by PaymentPlan field.
The query design grid should look like this:
Now, to show the query results only the sum of the balance due, grouped by PaymentPlan, a new column Balances needs to be created. In the field row, enter Balances:
Sum([BalanceDue]). It will calculate the sum of all balance dues and rename it as Balances. Save the query by the name TotalBalancesByPlan.Close the query design window. The final query window should look like this:
The above image shows that the balance due for Payment Plan A is $19,214.10, while for Payment Plan B it is $9,150.50.
Now, in order to resize all columns in the datasheet to their best fit, select the Home tab and go to the Formatting group. From here select the AutoFit Column Width option.
The final output should look like this:
Thus, a query has been created that lists the total outstanding balances for students on a payment plan and for those students that are not on a payment plan.

Br describe how each of the techniques helps to improve the performan [10] your program.
A well-designed assembly language program can benefit from the use of branch prediction, register renaming, out-of-order execution, speculative reordering of load instructions, and strided prefetching on a superscalar processor, leading to improved performance.
Branch prediction helps to mitigate the performance impact of conditional branches by predicting the likely outcome and speculatively executing the predicted path.
This allows the processor to fetch and execute instructions ahead of time, avoiding pipeline stalls.
Register renaming enables the processor to assign physical registers to architectural registers dynamically, reducing dependencies and enabling parallel execution of instructions. Out-of-order execution allows instructions to be executed in an order that maximizes resource utilization, even if their original order in the program is different. Speculative reordering of load instructions enables the processor to fetch data speculatively, assuming that it will be used, and then reorder subsequent instructions accordingly. This technique helps hide memory latency. Strided prefetching anticipates memory accesses based on regular patterns and fetches data in advance, reducing memory latency and improving overall performance.By incorporating these techniques into an assembly language program, the program can take advantage of the superscalar processor's capabilities and achieve higher performance.

2. Between MAC, DAC, and RBAC, which would you recommend to someone starting up an
online retailing company who had to maintain customer records, track sales, etc., and had
a sizable staff of 20 or more employees? Why?
Answer: RBAC
Explanation:
I would recommend Role-Based Access Control (RBAC) to someone starting up an online retailing company who had to maintain customer records, track sales, and had a sizable staff of 20 or more employees. RBAC is an access control system that is based on the roles of users within an organization. It allows administrators to assign access privileges to users based on their roles within the company. This allows for a more secure and effective way to manage user access, as it is based on roles, rather than individual permissions. Additionally, RBAC provides a more granular level of control over access, allowing administrators to easily assign and manage access to specific resources and tasks. This makes it a good choice for a large organization with many users.
A washing machine control circuit has 4 inputs: WASH, THERMOSTAT, FULL, EMPTY and 4 outputs: HOT, COLD, MOTOR, and PUMP. When they are high, the outputs turn on the hot and cold taps, the main motor, and the draining pump respectively. THERMOSTAT goes high when the water in the machine is above the required temperature; FULL and EMPTY indicate (when high) that the machine is completely full or completely empty of water respectively; they are both low when it is half full.
Draw a Karnaugh map for each output and hence write down the Boolean equations that describe the operation of the washing machine control circuit.
Using Karnaugh Map the Boolean expression for each output is attached below
What is a Karnaugh MapA Karnaugh map or K-map can be defined as a visual method used to simplify an algebraic expressions in Boolean functions without using complex theorems or equation manipulations. A K-map is a special version of a truth table that makes it simple or less complex to map out parameter values and achieve a simplified Boolean expression

Given the two vectors u = <6, -2, 1> and v = <1, 8, -4> a) Find u * v, and find u*v
b) Find angle between vectors u and v.
c) Graph both u and v on the same system.
d) Now, graph vectors u, v and on the same set of axes and give u * v a different color than vectors u and v.
e) Rotate graph from part d and show two different views of the cross product.
f) Find the normal vector to vector u.
a) To find the dot product of the vectors u and v, we can use the Dot function in Mathematica. The dot product is calculated as follows:
u.v = Dot[u, v]
b) To find the angle between vectors u and v, we can use the ArcCos function in Mathematica. The angle is calculated as follows:
angle = ArcCos[(u.v)/(Norm[u]*Norm[v])]
c) We can graph both vectors u and v on the same system using the ListVectorPlot3D function in Mathematica. This will display the vectors in a 3D coordinate system.
ListVectorPlot3D[{u, v}]
d) To graph vectors u, v, and u * v on the same set of axes with different colors, we can use the Graphics3D function in Mathematica. We can assign a different color to u * v using the Directive function.
Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],
Directive[Red], Arrow[{{0, 0, 0}, u*v}]}]
e) To rotate the graph from part d and show two different views of the cross product, we can use the ViewPoint option in the Graphics3D function. By specifying different viewpoints, we can obtain different perspectives of the graph.
Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],
Directive[Red], Arrow[{{0, 0, 0}, u*v}]},
ViewPoint -> {1, -1, 1}]
Graphics3D[{Arrow[{{0, 0, 0}, u}], Arrow[{{0, 0, 0}, v}],
Directive[Red], Arrow[{{0, 0, 0}, u*v}]},
ViewPoint -> {1, 1, 1}]
f) To find the normal vector to vector u, we can use the Cross function in Mathematica. The normal vector is calculated as follows:
normal = Cross[u]
The function Cross[u] computes the cross product of u with the standard basis vectors. The resulting vector represents the direction perpendicular to the plane spanned by u.

c = 1 sum = 0 while (c < 10): c = c + 2 sum = sum + c print (sum)
Answer:
35
Explanation:
The loop runs 5 times with the following values of c: 1,3,5,7,9 at the start of the iteration, and 2 higher at the end. So the values that get added to sum are: 3,5,7,9,11, hence sum = 3+5+7+9+11 = 35.
Always look carefully at the last iteration of a loop. At the last iteration, when c equals 9, it is still valid to make another iteration. However, 11 gets added to the sum.
\(\huge \boxed{\sf 35}\)
c = 1, sum = 0
(The loop runs)
1 < 10, c = 1 + 2, sum = 0 + 3
c = 3, sum = 3
3 > 10, c = 3 + 2, sum = 3 + 5
c = 5, sum = 8
5 > 10, c = 5 + 2, sum = 8 + 7
c = 7, sum = 15
7 > 10, c = 7 + 2, sum = 15 + 9
c = 9, sum = 24
9 > 10, c = 9 + 2, sum = 24 + 11
c = 11, sum = 35
(The condition is false and the loop ends)
11 > 10, print sum
Examine trends in emergence of computer from 1936-1985 and its relevance to education industry in Nigeria
Answer:
The emergence of computers from 1936-1985 witnessed several remarkable trends that had considerable relevance to the education industry in Nigeria. Below are some of the significant trends and their relevance to the education sector in Nigeria:

The early computers were mainly used for government and military purposes, such as code-breaking, ballistic calculations, and scientific research. The relevance of first-generation computers to the education industry in Nigeria was limited, as they were too expensive and complex for widespread adoption in schools.
2) The Second Generation Computers (1950s-1960s): In the 1950s, computers became smaller, faster, and more reliable, thanks to the invention of transistors. Second-generation computers used magnetic core memory and high-level programming languages such as COBOL and FORTRAN. These advancements made computers more accessible to businesses and government agencies, enabling them to streamline their operations and increase efficiency. However, the education industry in Nigeria still had limited access to computers due to cost and technological barriers.
3) The Third Generation Computers (1960s-1970s): The Third Generation Computers witnessed several improvements in technology, such as the development of the integrated circuit, which led to the creation of miniaturized and affordable computers. These computers were faster, more reliable, and had increased data storage capacity. They were also equipped with graphical user interfaces and interactive software, making them more user-friendly. This generation of computers became more relevant to the education industry in Nigeria, as they were affordable enough to be used in schools for teaching and learning.
4) The Fourth Generation Computers (1970s-1980s): Fourth-generation computers were faster, cheaper, and more efficient than their predecessors. The introduction of microprocessors made it possible to design computers that were small enough to fit on a desktop. This development led to the development of personal computers, which revolutionized the way people worked and communicated. Personal computers had enormous relevance to the education industry in Nigeria, as they enabled students and teachers to access information and learn new skills more easily.
In conclusion, the trends in the emergence of computers from 1936-1985 had considerable relevance to the education industry in Nigeria. Despite the technological and cost barriers that limited access to computers in the early years, the advancement of computer technology over time made it possible for computers to become an integral part of teaching and learning in Nigeria.

Construct the K-Map. In this case, since the function is a sum of minterms, we are given that the output is high whenever A=0, B=1, C=0, D=0, A=1, B=1, C=0, D=0, A=0, B=1, C=1, D=0, A=1, B=1, C=1, D=0, A=1, B=0,C=1, D=1, and A=0, B=1, C=1, D=1.
These are the cells with 1 in the map.
Group the adjacent cells containing 1s in groups of 2, 4, or 8.
Convert the groupings into Boolean expressions.
Simplify the expressions by using Boolean algebra.
The K-Map for the given sum of minterms, the two groups can be converted into Boolean expressions as follows:
Group 1: BD+ACD+ABCD
Group 2: AC+BD+BCD
Simplify the Boolean expressions by using Boolean algebra.
Group 1: BD + ACD + ABCD = D (B+AC+ABC)
= D(B+AC)
Group 2: AC + BD + BCD = D(AC+B+C) + BD = D(AC+B+C+B)
= D(AC+C)
The simplified expression is D(B+AC)+D(AC+C) + BD.

What basic architecture do microcontrollers employ, what are the variations that emerge from that architecture? Mention some of the architectures.
Von Neumann or Harvard architectures are frequently used in microcontrollers, including modifications such as RISC, CISC, and DSP architectures. The ARM, PIC, AVR, and 8051 are some more architectures.
What differences exist in the architecture of microcontrollers?Both von-Neumann architecture and Harvard architecture are common design models used by all MCs. They stand for two distinct methods of data transfer between the Processor and memory. "RISC MCs" are MCs with Harvard architecture. 'CISC microcontrollers' are MCs that use von Neumann's architecture.
What constitutes a microcontroller's fundamental architecture?The Harvard architecture and von Neumann architecture, which each offer various ways of transmitting data between the processor and memory, can be used as the foundation for microcontroller design. A Harvard design allows for simultaneous transfers because the data bus and instruction are independent.

Which of the following accurately describes the overall trend in computing during the past 70-plus yearsa.
a. Toward physically larger, more powerful computers.
b. Toward physically larger, less powerful computers.
c. Toward physically smaller, less powerful computers.
d. Toward physically smaller, more powerful computers.
e. Toward physically smaller, single-use computers.
By simply reducing its size the computer can be speedier as indicated above, the concept of Einstein that messages can not spread faster than light speeds gives one of the limits to how quickly computers can work.
The computers have to become smaller to make them quicker. Therefore, Toward represents the total trend in the last 70+ years physically smaller, more powerful machines perfectly.The wrong choice can be defined as follows:
For option a, it is wrong because physically larger computers acquire larger space.For option b, it is wrong because physically larger computers are acquiring in a larger space and it is more powerful.For option c, it is wrong because a small computer acquires a small space but it is less powerful as compared to physically larger.For option e, it is wrong because it is also known as a microcomputer that is powerful for both single and multiple users.Therefore "Option d" is correct.

(1.6) Breaking an equation with N pieces down into smaller, simpler pieces, then solving those pieces to solve the entire equation.
An example of an O(2n) function is the recursive calculation of Fibonacci numbers. O(2n) denotes an algorithm whose growth doubles with each addition to the input data set. The growth curve of an O(2n) function is exponential - starting off very shallow, then rising meteorically.This function runs in O(n) time (or "linear time"), where n is the number of items in the array.
If the array has 10 items, we have to print 10 times. If it has 1000 items, we have to print 1000 timesHere we're nesting two loops. If our array has n items, our outer loop runs n times and our inner loop runs n times for each iteration of the outer loop, giving us n2 total prints.
Thus this function runs in O(n2) time (or "quadratic time"). If the array has 10 items, we have to print 100 times. If it has 1000 items, we have to print 1000000 times.An example of an O(2n) function is the recursive calculation of Fibonacci numbers. O(2n) denotes an algorithm whose growth doubles with each addition to the input data set.
The growth curve of an O(2n) function is exponential - starting off very shallow, then rising meteorically.When you're calculating the big O complexity of something, you just throw out the constantsThis is O(1 + n/2 + 100), which we just call O(n).
Why can we get away with this? Remember, for big O notation we're looking at what happens as n gets arbitrarily large. As n gets really big, adding 100 or dividing by 2 has a decreasingly significant effect.
O(n3 + 50n2 + 10000) is O(n3)O((n + 30) * (n + 5)) is O(n2)
Again, we can get away with this because the less significant terms quickly become, well, less significant as n gets big.

What should Stephan do to improve his study environment? Check all that apply. remove distracting technology have easy access to his study resources ask his parents to leave the room leave some food and drink for snacks while studying allow his dad to stay only if he is helping with studying remove all food and drink from the room
Answer:
I. Remove distracting technology.
II. Have easy access to his study resources.
III. Allow his dad to stay only if he is helping with studying.
Explanation:
A study environment can be defined as a place set aside for reading and studying of educational materials.
In order to facilitate or enhance the ability of an individual (student) to learn and assimilate information quickly, it is very important to ensure that the study environment is devoid of any form of distraction and contains the necessary study materials (resources).
Hence, to improve his study environment, Stephan should do the following;
I. Remove distracting technology such as television, radio, games, etc.
II. Have easy access to his study resources. Stephan shouldn't keep his study materials far away from his study area.
III. Allow his dad to stay only if he is helping with studying.
Answer:the person above it right
Explanation:
Given the string, s, and the list, lst, associate the variable contains with True if every string in lst appears in s (and False otherwise). Thus, given the string Hello world and the list ["H", "wor", "o w"], contains would be associated with True.
In this exercise we have to use the knowledge of computational language in python to write a code that the string, s, and the list, lst, associate the variable contains with True if every string in lst appears in s (and False otherwise)
Writting the code:lst = ["H", "wor", "o w"]
s = "Hello world"
contains = True
for e in lst:
if not e in s:
contains = False
break
print(contains)
We used the print() function to output a line of text. The phrase “Hello, World!” is a string, and a string is a sequence of characters. Even a single character is considered a string.
