Question Description 1. In this example of a nested IF Statement, breakout and explain each part of formula to determine how the commission rates will be calculated: IF(B2>=150, 10%, IF(B2>=101, 7%, IF(B2>=51, 5%, IF(B2>=1, 3%,"")))). 2.Why would you use a Vlookup function as oppose to a Nested If statement? 3.Give a real-life scenario in which you may have used or can implement the Nested If or Vlookup functions in your daily or weekly tasks.
please do the following in c++ A school has 100 lockers and 100 students. All lockers are closed on the first day of school. As the students enter, the first student, denoted S1, opens every locker. Then the second student, S2, begins with the second locker, denoted L2, and closes every other locker. Student S3 begins with the third locker and changes every third locker (closes it if it was open, and opens it if it was closed). Student S4 begins with locker L4 and changes every fourth locker. Student S5 starts with L5 and changes every fifth locker, and so on, until student S100 changes L100.After all the students have passed through the building and changed the lockers, which lockers are open? Write a program to find your answer and display all open locker numbers separated by exactly one space.(Hint: Use an array of 100 bool elements, each of which indicates whether a locker is open (true) or closed (false). Initially, all lockers are closed.)

USE SIMPLE JAVA CODE PLEASE The program will read and parameter file which defines necessary parameter to decide how each fragment will be access in term of the expected cost of query and update, expected probability of query and update to each fragment. Your program should be able to find and print optimal allocation for each fragment and display the overall cost of all possible replication as well. The optimal replication which is the lowest cost among all should be also printed. #Total number of fragment 3 #Expected cost of a remote query to fragment i. 1.0, 1.0, 1.3 #Expected cost of a remote update to fragment i. 1.2, 1.5, 2.0 #Number of sites 4 #Expected probability that fragment i is queried by site j. 1.0, 1.0, 0.4, 0.0 0.0, 0.4, 0.7, 1.0 0.0, 1.0, 1.0, 0.0 #Expected probability that fragment i is updated by site j. 0.6, 0.4, 0.0, 0.0 0.0, 0.0, 0.4, 0.6 0.0, 0.5, 0.5, 0.0

Grand Child process ID: ... But when I run the code, the Grand Child processes are not displaying in sequential order as shown in the output. I am trying to write a C program such that the parent process will create one child process and 3 grandchild processes and print their IDs. The Grand Child processes must appear in order of 3,4 and 5. I am attaching my code below. Please tell me what should I change in the code to get the desired output.

Problem You have a fence post located at the point (x,y) where a goat is tethered by a rope. You also have a house, which is a rectangle with diagonally opposite corners at the points bottom-left: (x1,y1) and top-right: (x2,y2). You want to pick a length of rope that guarantees the goat cannot reach the house. Determine the minimum distance from the fence post to the house, so that you can make sure to use a shorter rope. Recall that the distance formula is: (x2−x1)2+(y2−y1)2 The input consists of a single line containing six space-separated integer values: x, y, x1, y1, x2, and y2. You are guaranteed that x1<x2 and y1<y2, and that (x,y) is strictly outside the axis-aligned rectangle with corners at (x1,y1) and (x2,y2). Return the minimum distance from the goat’s post to the house as a floating-point value from main(). Learning Objectives Be able to create a program with a lesser template. Be able to calculate the min/max of integers. Be able to write a mathematical…
You should submit a script file and a plain text output file (.txt) that contains the test output. Multiple file uploads are permitted. Don’t forget to include descriptive comments in your Python code. Your submission will be assessed using the following Aspects. Does the submission include the is_divisible function from Section 6.4 of the textbook? Does the submission implement an is_power function that takes two arguments? Does the is_power function call is_divisible? Does the is_power function call itself recursively? Does the is_power function include code for the base case of the two arguments being equal? Does the is_power function include code for the base case of the second argument being "1"? Does the submission include correct output for the five test cases?
