Answer and Explanation:
For the training set consist of 1000 observations, let's have a set consist of the observations such as sets.seed train boost.caravan gbm(Purchase., data = Caravan.train , distribution = "gaussian" , n trees = 1000 summary(boost.caravan) The tree classification such as tree(formula = Purchase data - train where variable are used in tree construction and number of terminal nodes 0 and deviance is 0.7 and error is 0.165
g Add a throw statement to the processNumbers function that throws the message "An element in the list is not a number." if one of the elements in toProcess is not a number. Hint: The function isNaN() returns true if the parameter is not a number.
Answer and Explanation:
function processNumbers(alist){
var Ourarray= new array(alist);
Ourarray.foreach(
if(isNaN()){
Console.log( "An element in the list is not a number."};
break;
}
}
processNumbers(alist)
From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.

What is the easiest way to deploy a C++ program to a user’s computer? a. Copy the source code to the user’s computer and then compile it b. Create a batch file that copies the program to the user’s computer and then run it c. Copy the executable file to the user’s computer d. Create an installer program and then run it on the user’s computer
Answer:
c. Copy the executable file to the user’s computer
Explanation:
When you run a c++ program, an executable file (.exe) is created in the same directory with the source file.
To deploy this program on another system, you need to transfer the executable file from the original system where the program was executed to the new system.
The program will work fine without errors.
However, do not mistake the executable file for the source file. The source file ends in .cpp.
If we are transferring data from a mobile device to a desktop and receive an error message that the mobile device has stopped communicating with the desktop, what is most likely the root cause?
a. the physical head on the cable os not the correct type
b. one of the ports on either device is damaged or under powered
c. the computer is not running the correct application
d. cable is not the correct color
Answer should probably be B. I don’t think you’d need an application to transfer data, and the computer wouldn’t even tell you if the data couldn’t transfer if you have the wrong cable head. It wouldn’t even be connected.
The root cause at the time when transferring the data from mobile device to the computer is that the port on the device is either damaged or it is underpowered.
The following are not the root causes for the error message at the time of transferring the data from a mobile device to the computer:
The cable is not of accurate type.The computer does not run the right application.The cable is not of accurate color.Therefore we can conclude that the root cause at the time when transferring the data from a mobile device to the computer is that the port on the device is either damaged or it is underpowered.

Explanation:
The operating system (OS) of an information system contains the software that executes the critical functions of the information system. The OS manages the computer's memory, processes, and all of its software and hardware. It allows different programs to run simultaneously and access the computer's memory, central processing unit, and storage.
a. True
b. False
Answer:
a. True
Explanation:
An information system (IS) can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.
Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.
Additionally, an information system comprises of five (5) main components;
1. Hardware.
2. Software.
3. Database.
4. Human resources.
5. Telecommunications.
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
On a related note, the software application that executes the critical functions of an information system (IS) are contained in its operating system (OS).
Basically, the computer's memory, processes, softwares and hardwares are typically being managed by the operating system (OS). Thus, an OS makes it possible for different programs to run simultaneously (more than one software program running concurrently) and access the computer's memory, central processing unit (CPU), and storage.

Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value))
Answer:
The program in Python is as follows:
current_price = int(input("Current Price: "))
last_price = int(input("Last Month Price: "))
change = current_price - last_price
mortgage = (current_price * 0.051) / 12
print('Change: {:.2f} '.format(change))
print('Mortgage: {:.2f}'.format(mortgage))
Explanation:
This gets input for current price
current_price = int(input("Current Price: "))
This gets input for last month price
last_price = int(input("Last Month Price: "))
This calculates the price change
change = current_price - last_price
This calculates the mortgage
mortgage = (current_price * 0.051) / 12
This prints the calculated change
print('Change: {:.2f} '.format(change))
This prints the calculated monthly mortgage
print('Mortgage: {:.2f}'.format(mortgage))
Answer:
current_price = int(input())
last_months_price = int(input())
change = current_price - last_months_price
mortgage = current_price * 0.051 / 12
print('This house is $', end= '')
print(current_price, end= '. ')
print('The change is $', end= '')
print(change, end= ' ')
print('since last month.')
print('The estimated monthly mortgage is $', end= '')
print(mortgage, end='0.\n')
Write a void function SelectionSortDescendTrace() that takes an integer array and sorts the array into descending order. The function should use nested loops and output the array after each iteration of the outer loop, thus outputting the array N-1 times (where N is the size).

Part 1 - Write the ingredients list to a file (10 points) Modify the program you developed for Lab 5 to make it output the data in the same format to a text file cake_ingredients_list.txt Note: Writing to a file is easier to code, so let's do that first. Hints: After the file has been opened, call the .write() function to write one line at a time to the file, in almost the exact fashion as calling print
Answer:
Explanation:
I do not have access to the ingredients list so instead I created the list and added the ingredients needed to make a cake. Then I used a for loop to loop throught the ingredients in the list and the .write() method to write the data to a text file with the same name as in the question. The code was tested and the output to the file can be seen in the attached image below.
ingredients = ['sugar', 'butter', 'eggs', 'vanilla', 'flour', 'baking powder', 'milk']
file = open('cake_ingredients_list.txt', 'w')
for ingredient in ingredients:
file.write(ingredient + '\n')

Consider an Erlang loss system. The average processing time is 3 minutes. The average inter-arrival time is 3 minutes. The number of servers is 3. What is r (sometimes referred to as the offered load)
Answer:
r = 1
Explanation:
Average processing time ( p ) = 3 minutes
Average inter-arrival time ( a ) = 3 minutes
number of servers ( m ) = 3
Determine the value of r
r ( offered load ) = p/a
= 3 / 3 = 1
∴ value of r ( offered load ) = 1

1. Create a pseudocode program that asks students to enter a word. Call a function to compute the different ways in which the letters that make up the word can be arranged.
2. Convert the pseudocode in question one to JavaScript and test your program.
Answer:
1)Pseudocode:-
Prompt user to enter string
Pass it to combination function which can calculate the entire combination and can return it in an array
In combination method -
Check if the string is length 2 size ie of 0 or 1 length then return string itself
Else iterate through string user entered
Get the present character within the variable and check if the variable is already used then skip
Create a string from 0 to i the index + (concatenate) i+1 to length and recursive call combination function and pass this string and store end in subpermutation array
For each recursive call push character + sub permutation in total arrangement array.
2)Code -
function combinations(userStr) {
/* when string length is less than 2 then simply return string */
if (userStr.length < 2) return userStr;
/* this array will store number of arrangement that word can be stored */
var totalArrangements = [];
/* iterate through string user enter */
for (var i = 0; i < userStr.length; i++) {
/* get the current character */
var character = userStr[i];
/*check if character is already used than skip */
if (userStr.indexOf(character) != i)
continue;
/* create a string and concanete it form 0 to i index and i+1 to length of array */
var str = userStr.slice(0, i) + userStr.slice(i + 1, userStr.length);
/* push it to totalArrangments */
for (var subPermutation of combinations(str))
totalArrangements.push(character + subPermutation)
}
/* return the total arrangements */
return totalArrangements;
}
/* ask user to prompt string */
var userStr = prompt("Enter a string: ");
/* count to count the total number of combinations */
let count = 0;
/* call function the return tolal number of arrangement in array */
totalArrangements = combinations(userStr);
/* print the combination in console */
for (permutation of totalArrangements) {
console.log(permutation)
}
/* total combination will be totalArrangements.length */
count = totalArrangements.length;
/*print it to console */
console.log("Total combination " + count)
