Write Octave commands in the script file that you just created to do the following: 1. Create a row vector r1 with six columns, where each of its elements is a 1. 2. Create a row vector r2 with six columns, where each of its elements is a 0. 3. Create a row vector r3 with six columns, where each of its elements is a random integer value between

Start with an R command which creates DataB, a vector filled with 1000 random numbers from the uniform distribution of integers between 1 and 1000, R uses a pseudo random number generator – the random numbers which are selected depends on the initial seed value for the RNG. Set.seed(10) DataB<-runif(n=1000, min=1, max=1000) Confirm that DataB[1] = 507 A. How many times does integer 23 appear in DataB? B. If the numbers in DataB are sorted from lowest to highest, what number is in location 23?
If a and b are two non-empty numerical row vectors (of different lengths) present in Matlab Workspace, what command would you use to create a new vector, called c, that is a combination of a and b (b elements are appended at the end of a)? c = a + b c = transpose(a,b) c = [a; b] c = [a, b]
Write a BASH SCRIPT or BASH COMMANDS. Make 2 arrays. One regular index array called array. One associative array called hash with 3 elements in it and a string variable called str with at least 5 characters where one of those characters is duplicated twice (i.e., in the string at least 3 times). Next echo both arrays as strings on a single line. Then save just a portion of your indexed array to a new array variable. Lastly write a loop to print out each item of the new array on a line by itself.
What does the following JavaScript code do (assume it is in a script element)?function myFcn( a, b, c ){ var q = b; q = c; return q;}var x = myFcn( 1, "stuff", "whatever" );document.write( "<p>" + x + "</p>" ); Select one: a. Nothing as there is an error in the code. b. Writes the string whatever to the web page. c. Writes the number 1 to the web page. d. Writes the string stuff to the web page.
Based on your algorithm(User valida- tion), write a program that does the same thing using HTML, CSS, and JavaScript. Use the scoring guide below: Import CSS design using link tag. The login page should be presentable. Import JavaScript using script tag Write JSON object in your JS file containing the following account: Username: john, Password: smith Username: mary, Password: woods Username: steve, Password: jobs •The program should be able to count the num- ber of login attempts. If it reaches the maximum threshold of 3 incorrect credentials, it should dis- able the login button. If the user was able to login with correct credentials(username and its corresponding password), use an alert to display ”successfully logged in!”. The program should be able to determine what goes wrong, for example, the ”user does not ex- ist” only appears when the username does not match to the accounts inside the JSON, and ”Incorrect password” if the username is correct…

Please Assist me to complete the Python Code: Data frames can be subset by a chosen value using ==. Ex: df[df.x == 5] gives all the rows in the data frame df for which the column x has a value of 5. Write a program that performs the following tasks: Load the file mtcars.csv into a data frame called df Create a new data frame df_cyl by subsetting the data frame based on a user defined value for the column cyl. Print the shape of the new data frame.mtcars.csv should not be necessary to answer this question. Please advise on the commands for subsetting a new data frame and for printing the shape of the new data frame. Thank You! Please try Completing the Program Below: import pandas as pd cylinders = int(input()) df = # read in the csv file mtcars.csv df_cyl = # create a new dataframe with only the rows where cyl = cylinders print(# print the shape of the new data frame)
How do I code a Python program where get request to / should return index.html, get request to /yourname should return the personal file and post request to /comment should prase the data from the post request body and send the text data back to the client?
Assuming that M is already a variable in the workspace and M contains numeric data in a matrix format, which of the following lines of code changes the value of M? Write your answer in a comment in your m file. List all correct answers. There could be more than one. M(:) x = M(end,:) M = M’ transpose(M) M = 1:10

For items 1–3, use the IN300_Dataset1.csv file. Write a Python program that reads the CSV file into a Panda dataframe. Using that dataframe, print the row, source IP, and destination IP as a table. Write a Java program that reads the CSV file into an ArrayList. Convert the ArrayList to a string array and print the row, source IP, and destination IP on the same line using a loop. Write an R program that reads the CVS file using the read.csv data type. Print the row, source IP and destination IP of each line.
Consider this code. Assume the axios files have been loaded from the CDN, and that our HTML includes a div element with an id='display'. function getQuote() { axios.get('http://ron-swanson-quotes.herokuapp.com/v2/quotes') .then( function(response) { quote = response.data[0]; document.getElementById('display').innerHTML = quote; }) .catch( function(error) { status = "An error occurred: " + error; }); } Why do we ask for the first element in the data array, data[0]? Because no matter what web service we request data from, that web service will always return a array of with a single element. Because we investigated the ron-swanson-quotes API, and it revealed that a request like the one we made returns an array with a single element. That element would be in index 0.
