Write a program in Java that asks the user to enter four weighted assessment grades, calculate the average, then display the average with the message: "Student Pass" if the average is greater than or equal 60 or the message "Student Fail" otherwise. The details of the assessments and weights are as follow: Homeworks: 20% Labs: 15% Midterm: 25% Final: 40%
Answer:
Explanation:
In order to calculate the weighted average, the grade itself is multiplied by the percentage of the category and then these values are summed. This sum is then divided by the total percentage of the portfolio.
import java.util.Scanner;
class Main {
public static void main(String[] args) {
double sumOfWeights = 100;
Scanner in = new Scanner(System.in);
System.out.println("Please Enter Homework Grade: ");
double homework = in.nextDouble() * 20;
System.out.println("Please Enter Labs Grade: ");
double labs = in.nextDouble() * 15;
System.out.println("Please Enter Midterm Grade: ");
double midterm = in.nextDouble() * 25;
System.out.println("Please Enter Final Grade: ");
double finals = in.nextDouble() * 40;
double average = (homework + labs + midterm + finals) / sumOfWeights;
System.out.println("The Average of these Weighted Grades is " + average);
}

Katie wants to use VLOOKUP for a column in a table. Which value of the mode parameter should she use to look for an exact match of the searched data?
Katie should use the __ value of mode parameter for an exact match with the searched data.

Activity in September 2014, the Federal Bureau of Investigation (FBI) announced that is next generation Idenufication system was fully functional The FBI named it the integrated Automated Fingerprint Identification system (IAFIS), Conduct online research on this system and answer the following questions 1. Which elements can be stored in IAFIS? 2. What is the response time of this system? 1. How has this system benefited the FBI

The system’s average response time for criminal fingerprint processing is about 27 minutes. Civil fingerprint processing takes over an hour.
Previously, the tenprint submission and identification was a manual, tedious process. It took the FBI weeks or months to process a single fingerprint submission. IAFIS has automated this process and added advanced identification capabilities. The submission and processing takes just few minutes. This has helped the FBI solve and prevent crime and tighten holds on criminals and terrorists.
