The system development life cycle (SDLC) consists of seven phases. At each phase, there are certain outcomes. Now match each outcome to the corresponding phase

Which of the following matches the description of each reaction? Reaction 1: Does an Anti-Markovnikov addition of H2O, a syn addition. Reaction: [Reaction1], Reagents: [Reagents1] Reaction 2: Does a Markovnikov addition of H2O, a anti-addition (this is different from Anti-Markovnikov), DOES NOT rearrange. Reaction: [Reaction2], Reagents: [Reagents2] Reaction 3: Does an Markovnikov addition of H2O, goes through a carbocation, can rearrange. Reaction: [Reaction3], Reagents: [Reagents3]

For the following code snippet, what will the value of sum be when counter equals 3? counter = 0sum = 0while counter

(Fill in the blank) When slicing a string, there are up to three numbers we specify like so: 1 my_string = “Hello_World!”2 print(my_string[1:2:3]) what is the output if the user enters 35.5 and then 30? On line 2 in the above code, 1 represents the [x1] index, 2 represents the [x2] index, and 3 represents the [x3] 

Which of the following is not a Boolean operator in Python?

Why might we need to use a while loop? Explain and provide an example (you do not need to code a while loop, just an example of where a while loop is beneficial compared to a non-iterative solution)  

What will be the output of:  result = 8 / 10print(f”The result of formatting this number is: {654321.109:,.2f}”)

What does the following code snippet do? (Do not explain each line of code. Do explain what does the code do as a whole.) num  = 0result = 0while num < 10:    if num % 2 == 0:        result += num    num += 1print(result)

Write a Python program that continuously asks the user to enter an item from a menu (1 for`burger` $8.5,  2 for`pizza` $10, 3 for`salad` $6.75,  4  for`drink` $2.5, or `done`). After selecting an item, the program should ask for the quantity and then add the cost to a running total. It should display the current total amount `Your current total is $23.75`. The program should only stop if the user enter `done` otherwise it will continue ask for more items and keep adding to the total.  Once the program displays the final total, it should then show another message based on the total cost: – When the total is 10 or less and greater than zero, display `”Light snack”`- When between 10 and 25 (exclusive), display `”Average meal”`- When between 25 (inclusive) and 50 (inclusive) , display `”Big appetite!”`- When more than 50, display `”Feast mode!”`- When the total is equal to zero, display `”Thanks for visiting us!”` Specifications: 1. Calculate the item total using the formula (price × quantity). 2. The program must use a `while` loop to repeatedly ask the user for menu selections until they are done. 3. The user should enter the menu choice as a number (1–4) or the word `done` to end the program. 4. Display a receipt showing current total amount , formatted with a dollar sign, commas for thousands, and rounded to two decimal places Extra Credit :   print a full receipt showing each item ordered, its quantity, and its total cost — followed by the grand total and category message.  Example Receipt — Order Summary —Burger (2)    $17.00Pizza  (0)    $0.00Salad  (0)    $0.00Drink  (1)    $2.50———————Total:         $19.50Average meal
