. Write programming code in C++ for school-based grading system
Explanation:
The grade must be calculated based on following pattern:
Average Mark RangeGrade91-100A181-90A271-80B161-70B251-60C141-50C233-40D21-32E10-20E2
Calculate Grade of Student in C++
To calculate grade of a student on the basis of total marks in C++ programming, you have to ask from user to enter marks obtained in 5 subjects. Now add marks of all the 5 subjects and divide it by 5 to get average mark. And based on this average mark, find grade as per the table given above:
// C++ Program to Find Grade of Student // -------codescracker.com------- #include<iostream> using namespace std; int main() { int i; float mark, sum=0, avg; cout<<"Enter Marks obtained in 5 Subjects: "; for(i=0; i<5; i++)
Select the scenario that describes a top-down approach to data warehouse design.
Cathy’s Cards and Gifts, which has three stores, creates data marts for its sales, marketing, and delivery departments to study the possibility of establishing a new store.
Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed.
Cynthia’s Florals, which is dealing with debt, creates new data marts for the service, delivery, and sales departments to develop a strategy to stay in business.
Connor’s Meat Market, which just opened, creates data marts to track the sale of each of the following meats: beef, pork, lamb, and fish.
Answer:
Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed.
The scenario defines a top-down approach to data warehouse design as "Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed".
What is a top-down approach to data warehouse design?In the "Top-Down" method system, a data warehouse exists defined as a subject-oriented, time-variant, non-volatile, and integrated data storage for the entire business data from various sources exist validated, reformatted, and saved in a normalized (up to 3NF) database as the data warehouse.
Therefore, the correct answer is option b) Crawford's Fabrics, which wants to expand its operations, combines data from the purchasing and sales departments into a central database, to be divided into new data marts as needed.

Kamal plans to offer new, more favorable contracts to business customers who are now receiving a discount and use wireless services. Determine whether each customer should receive a new contract as follows:
a. In cell 15, enter a formula using the AND function that tests whether the Wireless value is equal to "Y" and whether the Discount value is equal to "Y".
b. Fill the range 16:118 with the formula in cell 15.
Solution :
'AND" operation is a logical operation and is used in logical connective combining two statements and in truth tables.
Using AND operation verifies whether the outcome P and Q is true only when both the P as well as Q are true. If one of the P or Q is not true, then outcome result will be false.
In the context, Kamal wishes to offer a new and more favorable contracts to the business customers who use a wireless services and receive a discount.
Therefore, using the AND operation of the customers as :
Customer Wireless Discount Outcome
A N N FALSE
B Y N FALSE
C N Y FALSE
D Y Y TRUE
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.

Why are data silos problematic?
Answer:
Hampers collaboration
Resource wastage
Lack of data integrity
Explanation:
Data silos comes into play When different departments of an orgainiziations independently collects data needed for its operations. The finance, HR, administrative departments and so on collects their data and keeps it to themselves. As a result there is a repetitive and needless gathering and storage of already existing data, that is the data required by one group will have to be gathered again while it currently exists with another group. This leads to inefficient resource management and wastage. This practice also leads to data integrity as data stored differently across departments becomes inconsistent and less accurate over time. Team work and collaboration is gradually eroded as each group continues to hold on to its resources which poses a problem towards organizational growth.

I think you have been doing a great job but you haven’t been signing many people up for our new service feature I want you to set a goal of signing up 25% of your new customers for our new service feature if I get 96 new customers that means I have to get how many of them to sign up
Answer:
24 customers
Explanation:
Given
[tex]Customers = 96[/tex]
[tex]p = 25\%[/tex] --- proportion to sign up
Required
The number of customers to sign up
This is calculated as:
[tex]n = p * Customers[/tex]
So, we have:
[tex]n = 25\% * 96[/tex]
[tex]n = 24[/tex]

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.
A good machine should have the mechanical advantage of......?
Answer:
The ideal mechanical advantage (IMA) of an inclined plane is the length of the incline divided by the vertical rise, the so-called run-to-rise ratio. The mechanical advantage increases as the slope of the incline decreases, but then the load will have to be moved a greater distance.

Write a program named lastname_firstname_cities.py that works with information about large cities. Your program will open the cities.txt downloadfile. Each line in the file has the name of a city, its country, and its population. The first few lines of the file look like this:
Answer and Explanation:
Open your text editor and open new file. Save new file file as lastname_firstname_cities.py. The program will open the file cities.txt downloadfile hence :
dfile= open(cities.txt, "r")
If we write this into our lastname_firstname_cities.py file it will open our cities.txt downloadfile in read mode and text mode(by default unless we specify binary mode which is for images)
