Answer:
A series of update steps must be done in the required software; for example:
Explanation:
Option 1: add the timestamp at the top of the view :
Open a workbook containing the dashboard in Tableau Desktop, then go to the sheet where you want to show the time of the last data update.
-Select Worksheet> Show Title.
-Double-click on the title.
-In the Edit Title dialog box, select Insert> Data update time, and then click OK.
-Add any field to the filter shelf, leave all other selections blank, and click OK.
-Save the changes.
-Add sheet to dashboard.
Option 2: add the timestamp at the bottom of the view.
Open a workbook containing the dashboard in Tableau Desktop, then go to the sheet where you want to show the time of the last data update.
-Select Worksheet> Show Caption.
-Double-click the subtitle.
-In the Edit Subtitle dialog box, select Insert> Data update time, and then click OK.
-Add any field to the filter shelf, leave all other selections blank, and click OK.
-Save the changes.
-Add the sheet to the dashboard.
-Right-click on the sheet and select Caption to display the update time.
You can modify the size of these sheets in the dashboard to take up the space you consider necessary. They can also be set as floating objects, so they don't alter the size of the rest of the sheets in the view.
In the simulation, player 2 will always play according to the same strategy. The number of coins player 2 spends is based on what round it is, as described below. (a) You will write method getPlayer2Move, which returns the number of coins that player 2 will spend in a given round of the game. In the first round of the game, the parameter round has the value 1, in the second round of the game, it has the value 2, and so on. The method returns 1, 2, or 3 based on the following rules. If round is divisible by 3, then return 3. If round is not divisible by 3 but is divisible by 2, then return 2. If round is not divisible by 3 and is not divisible by 2, then return 1. Complete method getPlayer2Move below by assigning the correct value to result to be returned.
Final answer:
To determine the number of coins that player 2 will spend in a given round of the game, check the rules based on the value of the round: divisible by 3 = 3 coins, divisible by 2 but not by 3 = 2 coins, not divisible by 3 and not divisible by 2 = 1 coin.
Explanation:
To determine the number of coins that player 2 will spend in a given round of the game, we need to check the rules based on the value of the round:
If the round is divisible by 3, player 2 will spend 3 coins.
If the round is not divisible by 3 but is divisible by 2, player 2 will spend 2 coins.
If the round is not divisible by 3 and not divisible by 2, player 2 will spend 1 coin.
So, the method getPlayer2Move should be defined as follows:
public
int getPlayer2Move(int round)
{
if (
round % 3 == 0) { return 3;
}
else if
(
round % 2 == 0
) {
return 2;
} else {
return 1;
} }
Final answer:
The getPlayer2Move method returns 1, 2, or 3 based on the given rules.
Explanation:
The method getPlayer2Move returns 1, 2, or 3 based on the rules given in the question. If the round number is divisible by 3, the method returns 3. If the round number is not divisible by 3 but is divisible by 2, the method returns 2. If the round number is not divisible by 3 and not divisible by 2, the method returns 1. For example, if the round number is 4, which is divisible by 2 but not divisible by 3, the method would return 2.
Our goal here is to predict whether an accident just reported will involve an injury (MAX_SEV_IR = 1 or 2) or will not (MAX_SEV_IR = 0). For this purpose, create a dummy variable called INJURY that takes the value "yes" if MAX_SEV_IR = 1 or 2, and otherwise "no."
Explanation:
The outlines given in question statement can be written in many programming languages. The below program would be written in C language, which is one of the basic computer languages
Program code
String main (int MAX_SEV_IR)
{
string INJURY
if (MAX_SEV_IR = =1 or MAX_SEV_IR == 2)
INJURY = "yes"
elseif (MAX_SEV_IR = =0)
INJURY = "No"
else
INJURY = "Invalid data"
return INJURY
}
Answer:
# main function is defined
def main():
# the value of MAX_SEV_IR is gotten
# from the user via keyboard input
MAX_SEV_IR = int(input ("Enter MAX_SEV_IR: ")
# if statement to check for prediction
# if MAX_SEV_IR == 1 or 2
# then there is injury and it is displayed
if (MAX_SEV_IR == 1 or MAX_SEV_IR == 2):
print("INJURY = ", injury)
print("PREDICTION: Accident just reported will involve an injury")
# else if MAX_SEV_IR == 0 then no
# injury and it is displayed
elif (MAX_SEV_IR == 0):
injury = "NO"
print("INJURY = ", injury)
print("PREDICTION: Accident just reported will not involve an injury")
# the call main function to execute
if __name__ = '__main__':

The WorkOrders table contains a foreign key, ClientNum, which must match the primary key of the Client table. What type of update to the WorkOrders table would violate referential integrity? If deletes do not cascade, what type of update to the Client table would violate referential integrity? If deletes do cascade, what would happen when a client was deleted?
Answer:
Changing the customer number on a record in the Orders table to a number that does not match a customer number in the customer table would violate referential integrity.
If deletes do not cascade, deleting a customer that has orders would violate referential integrity.
If deletes cascade, customer can be deleted and all orders for that customer will automatically be deleted.

To help his customers visualize the types of homes he can build for them, he designs five different models on the computer, using 3D printing to develop 3D paper models. What type of technology is Daniel using to develop these 3D models
Final answer:
Daniel is employing Computer-Aided Design (CAD) software and 3D printing to create 3D models for his construction company. This allows for detailed, precise visualizations and virtual tours of home designs, aiding clients in understanding the end product before building commences.
Explanation:
Daniel is using Computer-Aided Design (CAD) software coupled with 3D printing technology to develop the 3D models. CAD software allows users to create detailed, precise representations of products, buildings, and other projects, which then can be used to create physical models through 3D printing. This method is widely utilized in various industries, including construction, architecture, and product design to facilitate visualization and prototyping. The realistic representations and simulations provided by today's CAD programs help professionals like Daniel to effectively communicate design concepts to clients without the need for traditional physical mock-ups, enhancing the design process significantly.
Through this technology, Daniel can construct virtual tours offering exact views of the architectural designs. These models not only help in visualizing the structures but also in making more informed decisions on the design before any actual construction begins. Daniel's utilization of technology for creating 3-dimensional paper models demonstrates how contemporary architectural practices leverage digital tools to bring concepts to life for both the design teams and their clients.
Please construct a program that reads the content from the file numbers.txt. There are two lines in the file, each is an integer number. Print out the two numbers and their sum in an equation as below: Content in numbers.txt: 45 28 Output of the program: 45 28
Answer:
file = open("numbers.txt")
numbers = []
for line in file:
numbers.append(int(line))
print("The numbers in the file: " + str(numbers[0]) + " " + str(numbers[1]))
print("The sum of the numbers: " + str(numbers[0] + numbers[1]))
Explanation:
The code is in Python.
Open the file named numbers.txt
Create an empty list, numbers, to hold the numbers in the file
Create a for loop that iterates through file and adds the number inside the file to the list
Print numbers
Calculate and print the sum of the numbers
Final answer:
To read two integers from a file and print their sum, use a Python script to open the file, convert the strings to integers, calculate the sum, and print the results with the equation format.
Explanation:
To construct a program that reads the content from the file numbers.txt and prints out the two numbers along with their sum, you would need to use a programming language. Below is an example of how you might write such a program in Python:
with open('numbers.txt', 'r') as file:
numbers = file.read().splitlines()
num1 = int(numbers[0])
num2 = int(numbers[1])
sum_of_numbers = num1 + num2
print(f"{num1} + {num2} = {sum_of_numbers}")
This program opens the file numbers.txt, reads its content line by line, converts the lines to integers, and then calculates their sum. Finally, it prints out the numbers and the sum in the format specified. It is assumed that numbers.txt contains one number per line and that these can be converted directly to integers.

Consider the following line of code: if (x < 12 || (r – 3 > 12)) Write three valid mutants of this ground string (based on the rules of the Java/C# language), followed by three invalid mutants. You must use a different mutant operator for each mutant you create – list the abbreviation for the operator used next to each line (for example, write "ROR" if you used a Relational Operator Replacement).
Answer:
See explaination
Explanation:
Mutation Testing:
Mutation Testing is a type of software testing where we mutate (change) certain statements in the source code and check if the test cases are able to find the errors. It is a type of White Box Testing which is mainly used for Unit Testing. The changes in the mutant program are kept extremely small, so it does not affect the overall objective of the program.
We say a mutant is valid if it is syntactically correct. We say a mutant is useful if, in addition to being valid, its behavior differs from the behavior of the original program for no more than a small subset of program test cases.
VALID MUTANTS
1. if (x < 12 && (r – 3 > 12)) LOR
2. if (x < 12 || (r – 3 < 12)) ROR
3. if (x < 12 || (x – 3 < 12)) IVR
INVALID MUTANTS
1. if (x < 12 ||(r – 3 > 12) UPR
2. if (x < 12 (r – 3 < 12)) MLO
3. (x < 12 || (x – 3 < 12)) CSM
Note:
LOR: LOGICAL OPERATOR REPLACEMENT
ROR: RELATIONAL OPERATOR REPLACEMENT
IVR: INVALID VARIABLE REPLACEMENT
UPR: UNBALENCED PARANTHISIS REPLACEMENT
MLO: MISSING LOGICAL OPERATOR REPLACEMENT
CSM: CONTROL OPERATOR MISSING REPLACEMEN

An array of String objects, words, has been properly declared and initialized. Each element of words contains a String consisting of lowercase letters (a–z). Write a code segment that uses an enhanced for loop to print all elements of words that end with "ing".
As an example, if words contains {"ten", "fading", "post", "card", "thunder", "hinge", "trailing", "batting"}, then the following output should be produced by the code segment.
fading trailing batting
Write the code segment as described above. The code segment must use an enhanced for loop.
Answer:
Explanation:
#include <iostream>
using namespace std;
int main()
{
string cwords[8]={"ten", "fading", "post", "card", "thunder", "hinge", "trailing", "batting"};
string temp="";
for (int i=0; i<8; i++)
{
temp=cwords[i];
int j=temp.length();
if (temp[j-3]=='i' && temp[j-2]=='n' && temp[j-1]=='g')
{
cout<<temp<<endl;
}
}
return 0;
}
The code segments must use an enhanced for loop given in the coding language.
What are code segments?A code segment is a chunk of an object file or the corresponding area of the program's source code that is used for programming. It is also referred to as a text segment or simply as text.
#include <iostream>

Derived class: 9
16 Hello Base
Explanation:
The header files #include <iostream> #include <string> was wrongly included in the question this had to be edited.
After properly editing the programme to remove errors, the expected output when you run the code is:
0 This is base class
Derived class: 9
16 Hello Base
Final answer:
The C++ program demonstrates class inheritance and method overriding. The output for the baseClass object is "2 This is the base class", and for the derivedClass object is "Derived class: 7" followed by "10 Hello Base".
Explanation:
The provided C++ program defines two classes, baseClass and derivedClass, which demonstrate basic inheritance and method overriding. The main() function creates instances of these classes and calls their print() methods. The output of this program is determined by the details of the print methods.
When baseObject.print() is called, it triggers baseClass::print(), outputting the value of x and str for the base object, which are initialized in the baseClass constructor. The output would be "2 This is the base class".
Calling derivedObject.print() triggers derivedClass::print(), which first outputs the phrase "Derived class: " and the value of y from the derivedClass object, followed by the properties of the base class part of the same object, as per the constructor which passed "Hello Base", a (x in the base class), and the sum a + b. The resulting output would be "Derived class: 7" followed by "10 Hello Base" on a new line.
As we discussed in class, with the explosion of huge volumes of unstructured data, a new breed of database technologies have emerged and have become popular. Clearly, these new database technologies like Dynamo, Bigtable, and Cassandra are critical technology to the companies that created them. Why did they allow their employees to publish academic papers about them? Why did they not keep them as proprietary secrets? (
1. The reason that Am..on (creator of Dynamo), G..gle (creator of Bigtable), and F...book (creator of Cassandra) allowed their employees to publish academic papers about the new breed of database technologies is that technologies were custom-made.
A custom-made technology is created specifically to meet some peculiar business strategies and cannot be utilized elsewhere.
2. The reason the companies did not keep these technologies as proprietary secrets is that other companies cannot use the technologies in their businesses since they were created to meet specific business requirements.

Final answer:
Companies like those who created Dynamo, Bigtable, and Cassandra published academic papers about their innovations to establish themselves as leaders, attract top talent, and foster adoption of their technologies as industry standards, despite the potential risk of giving away proprietary information.
Explanation:
The question asks why companies like those who created Dynamo, Bigtable, and Cassandra chose to publish academic papers about their database technologies, rather than keeping them as proprietary secrets. The decision to openly disclose information about these new database technologies can be attributed to several strategic advantages. First, publishing helps in establishing these companies as leaders in technological innovation, attracting top talent who want to work on cutting-edge projects. Furthermore, by sharing the innovations, these companies foster a community of developers who can contribute to the improvement of the technology, indirectly benefiting the original creators. Lastly, it encourages the adoption of their technologies as standards in the industry, which can lead to wider use and integration into other services, products, and technologies.
These reasons collectively contribute to why companies might decide to publish their innovations in the realm of big data and database technologies. Even though it might seem counterintuitive at first to share proprietary technologies, the long-term benefits of establishing industry standards, fostering a collaborative ecosystem, and attracting top talent can outweigh the risks of competitors gaining insights into their technologies.
Enter a formula in cell B25 to calculate the daily bill for Monday, July 29. The formula should calculate the total billable hours for the day (cell B23) times the billable rate (B4). Be sure to use an absolute cell reference for the billable rate.
Answer:
=($B$4 * B23)
Explanation:
Given
Billable Rate: B4
Total Billable Hours: B23
Required:
Daily Bill: B25
Write the following formula in cell B25
=($B$4 * B23)
The question asks that the cell for billable rate should be referenced using the absolute cell reference.
To use absolute reference in a cell, we start by writing a dollar sign and we also separate the cell name and the cell number with a dollar sign.
Hence, cell B4 becomes $B$4
Also, the question asks that the cell $B$4 be multiplied by cell B23.
To write a formula in Excel, we start by writing the equal to sign (=), then we continue with the expression itself
$B$4 multiplied by cell B23 will be written as $B$4 * B23
So, the full formula to calculate daily bill that'll be written in cell B25 becomes is =($B$4 * B23)
The Excel formula in cell B25 that can be used to calculate the daily bill for Monday, July 29 is =($B$4 × B23)
What is Excel Formula?
An excel formula represents the expression of a code in an Excel sheet that operates within a range of cell(s).
From the parameters given:
The billable rate = B4The total Billable hours = B23By using the absolute reference for billable rate, we need to begin the formula with a $ sign, the cell name in conjunction with the cell number is being separated by a $ sign.
Therefore, the cell in B4 can be written as:
$B$4Now, multiplying it with cell in B23, we have using the excel formula method, we have:
=($B$4 × B23)

Suppose that you sort a large array of integers by using a merge sort. Next you use a binary search to determine whether a given integer occurs in the array. Finally, you display all of the integers in the sorted array. a. Which algorithm is faster, in general: the merge sort or the binary search? Explain in terms of Big O notation. b. Which algorithm is faster, in general: the binary search or displaying the integers? Explain in terms of Big O notation.
Answer:
See explaination
Explanation:
Merge sort working-
1.type of recursive sorting algorithm.
2.divides given array into halves.
3. Sort each halves. Merge this halves to give a sorted array.
4. Recursive call continues till array is divided and each piece has only one element.
5. Merge this small pieces to get a sorted array.
Binary search-
1. It is a search algorithm.
2. Requires a sorted array to work on.
3.Works repetively dividing a half portion of list that could contain item until it has narrowed down the possible location to just one.
Comparing Merge sort and Binary Search using Big O notation-
Merge Sort - O(n*log(n)) in all scenario whether best, average or worst case.
Binary Search- O(log(n)) in average and worst case. O(1) in best case.
So seeing the above comparison Binary search is faster.
Comparing Binary search and displaying the integers-
Binary Search- O(log(n)) in average and worst case. O(1) in best case.
Displaying the integer-O(1) if already initialized, O(n) in case of loop or function.
So seeing above one can conclude that binary search is fast. But in best case both works in a similar manner.
Give a recursive algorithm to compute the sum of the cubes of the first n positive integers. The input to the algorithm is a positive integer n. The output is ∑j=1nj3. The algorithm should be recursive, it should not compute the sum using a closed form expression or a loop.
Answer:
def sum_cubes(n):
if n == 1:
return 1
else:
return n * n * n + sum_cubes(n-1)
print(sum_cubes(3))
Explanation:
Create a function called sum_cubes that takes one parameter, n
If n is equal to 1, return 1. Otherwise, calculate the cube of n, and add it to the sum_cubes function with parameter n-1
If we want to calculate the cubes of the first 3 numbers:
sum_cubes(3) = 3*3*3 + sum_cubes(2)
sum_cubes(2) = 2*2*2 + sum_cubes(1)
sum_cubes(1) = 1

Differences between the Services in career paths leading up to a joint assignment may surprise new staff Service members in joint assignments. This demonstrates which key element to remember when working with other services?
Answer:
Prior Experience Working with Senior Officers versus Little or None.
Explanation:
Differences and disparities between the Services in career paths leading up to a joint assignment may surprise new staff officers in joint assignments.
For example, Army and Air Force officers will likely come to a joint assignment with prior junior officer experience as an administrative “exec” to a senior officer at the O-5 and above level.
In contrast, Navy, Marine Corps and Coast Guard officers will have had no such experience unless selected for one of the highly competitive Flag Aide or Aide-de-Camp billets to an O-7 or above who rates such an aide.
Having an experience working with senior officers and when a person has little or none shows the key element to remember when working with other services.
What is the aim of joint operations?The act of working together in a joint project helps to provide some amount of guidance for the use of authority.
Note that having a previous experience in working with senior officers and when a person has little or none can be obviously shown when working with other services.
