Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20.

The program performs the following tasks:

Read the file name of the tsv file from the user. Assume the file name has a maximum of 25 characters.
Open the tsv file and read the student information. Assume each last name or first name has a maximum of 25 characters.
Compute the average exam score of each student.
Assign a letter grade to each student based on the average exam score in the following scale:
A: 90 =< x
B: 80 =< x < 90
C: 70 =< x < 80
D: 60 =< x < 70
F: x < 60
Compute the average of each exam.
Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one student per row and separate the values with a tab character.
Output the average of each exam, with two digits after the decimal point, at the end of report.txt. Hint: Use the precision sub-specifier to format the output.
Ex: If the input of the program is:

StudentInfo.tsv
and the contents of StudentInfo.tsv are:

Barrett Edan 70 45 59
Bradshaw Reagan 96 97 88
Charlton Caius 73 94 80
Mayo Tyrese 88 61 36
Stern Brenda 90 86 45
the file report.txt should contain:

Barrett Edan 70 45 59 F
Bradshaw Reagan 96 97 88 A
Charlton Caius 73 94 80 B
Mayo Tyrese 88 61 36 D

figure 4.3 illustrates the coverage of the classification rules r1, r2, and r3. determine which is the best and worst rule according to

Answers

In order to determine the best and worst rule according to the figure 4.3 which illustrates the coverage of the classification rules r1, r2, and r3, we need to understand what classification rules are and what they do. Classification rules are used in data mining and machine learning as a way of predicting outcomes based on a set of given inputs.

They are often used in applications such as fraud detection, product recommendation, and email spam filtering.The three classification rules illustrated in figure 4.3 are r1, r2, and r3. Each rule has a different level of coverage, which means that it is able to predict outcomes for a different set of inputs. The best rule would be the one that has the highest coverage, while the worst rule would be the one that has the lowest coverage.In order to determine which rule is the best and which one is the worst, we need to look at the coverage of each rule. According to figure 4.3, r1 has the highest coverage, followed by r3 and then r2. This means that r1 is the best rule, while r2 is the worst rule. R1 has a coverage of 80%, r2 has a coverage of 60%, and r3 has a coverage of 70%.In conclusion, based on figure 4.3, the best rule according to the coverage is r1 with 80% coverage, and the worst rule is r2 with only 60% coverage. R3 has a coverage of 70%.

When factoring a polynomial in the form ax2 + bx - c, where a, b, and c are positive real
numbers, should the signs in the binomials be both positive, negative, or one of each?

Answers

When factoring a polynomial in the form ax^2 + bx - c, where a, b, and c are positive real numbers, the signs in the binomials should be one of each, meaning one binomial should be positive and the other should be negative. Specifically, the binomials should be of the form (px + q)(rx - s), where p, q, r, and s are constants that depend on the values of a, b, and c.

you use the commond gmnome-sheel --replace at the command line and receive adn error message from the utility. what doest tshi indicate

Answers

The command line utility "gnome-shell --replace" is used to replace the existing user interface with a new user interface. Receiving an error message when running this command indicates that something is preventing the new user interface from loading.

Possible causes include: insufficient memory, incompatible graphic drivers, corrupted system files, or incorrect command syntax. It is important to investigate further to determine the exact cause of the error. If the cause of the error is not immediately apparent, troubleshooting techniques like running a system file check, updating or changing graphic drivers, and using the command line log files can help pinpoint the issue.

Additionally, if the error message includes specific technical information, it is often helpful to research that information to find additional resources. Finally, it is important to be sure to always use the correct syntax when running commands. Ultimately, an error message received when running the command "gnome-shell --replace" indicates that something is preventing the new user interface from loading. Investigating further is necessary to find the cause of the issue and resolve the problem.

When you import and transform data from an external source, you can add it to a worksheet with or without modifications.The following are the steps to add the transformed data to a worksheet.

Step 1: To transform the data, choose a data source and transform the data to fit your specifications in the Power Query Editor.

Step 2: Choose Close & Load from the Close & Load drop-down list in the Close & Load drop-down list in the Close & Load group on the Home tab on the Power Query Editor ribbon.

Step 3: The Load To page is where you can specify how the query results are displayed in the Excel workbook. Select Table, PivotTable Report, or PivotChart Report from the options.

Step 4: Select Existing worksheet and choose the location on the worksheet where the data should be placed from the options available.

Step 5: To finish the wizard and add the transformed data to the worksheet, click OK.This process saves a lot of time and helps to keep the data up to date with the source. Data should be updated on a regular basis to keep it current and to aid in making critical decisions based on accurate and current data.

TRUE/FALSE. Limited characteristics make it impossible for hash functions to be used to determine whether or not data has changed.

Answers

The given statement "Limited characteristics make it impossible for hash functions to be used to determine whether or not data has changed" is False because hash functions can be used to identify whether data has been altered, and their use is not restricted by limited characteristics.

A hash function is a method for creating a unique fixed-size digital fingerprint for a message of arbitrary length. The output, which is typically a short string of characters or numbers, is referred to as a hash, fingerprint, or message digest. It's worth noting that the hash function's output is always the same size regardless of the input's size. The hash function is used to validate the integrity of the transmitted data.

The hash function can quickly detect any changes made to the original data by recalculating the hash value and comparing it to the initial hash value. Hash functions can be used to detect whether or not data has been altered. It works by comparing the hash value of the original data with the hash value of the new data. If the hash values are the same, the data has not been altered. If the hash values are different, the data has been altered. Hash functions are widely used in computer security to ensure the integrity of data.

Hence, the given statement "Limited characteristics make it impossible for hash functions to be used to determine whether or not data has changed" is False.

What does sarah Bergbreiter mean by " there's still a long way to go"?

Answers

Without more context, it's difficult to say for sure what Sarah Bergbreiter meant by "there's still a long way to go." However, in general, this phrase is often used to mean that although some progress has been made, there is still much work to be done. It suggests that the current situation or achievement is not yet good enough or complete, and that more effort or time is needed to reach a desired goal.

In the context of robotics, Bergbreiter may be referring to the fact that although micro-robots have made significant advances in recent years, there are still many challenges that need to be overcome before they can be widely used in practical applications. These challenges could include things like improving their durability, increasing their power efficiency, and making them more reliable in complex environments. By saying that "there's still a long way to go," Bergbreiter may be emphasizing the need for continued research and development in this field.
