Lina20 [59]

Answer:

# the number of pizza is initialised

# to 5

number_of_pizza = 5

# number of slice in each pizza

# is initialised to 8

slice_in_each_pizza = 8

# total number of pizza is calculated

total_number_of_slices = number_of_pizza * slice_in_each_pizza

# number of guest who respond yes

# is initialised to 10

number_of_guest_respond_yes = 10

# additional 3 guest is added to existing guest

number_of_guest_respond_yes += 3

# number of left over slice is gotten by using modulo arithmetic

number_of_left_over_slice = total_number_of_slices % number_of_guest_respond_yes

# the number of left over slice

# is printed which is 1

print(number_of_left_over_slice)

Explanation:

Missing Question Part: Use a variable to store the number of pizzas ordered as 5.

Assuming there are 8 slices in each pizza, use a variable to store the total number of slices calculated using the number of pizzas ordered.

Use another variable to store the number of guests who had responded YES as 10.

Three more people responded YES. Update the corresponding variable using an appropriate expression.

Based on the guest count, set up an expression to determine the number of left-over slices if the slices would be evenly distributed among the guests. Store the result of the expression in a variable.

The program is written in Python and it is well commented.

The waterfall model and spiral model are variations of SDLC. Do some research to find out what they are and explain how these mo

Radda [10]

Waterfall model and spiral model are used in software development life cycle or SDLC. Any software development process follows one of these models depending on the type of software and the requirements of the customer.

Waterfall model

This model is called as sequential model since it works in stages. The output of first stage becomes the input of the second stage.

The errors of the first stage can be rectified only when it is completed. This is time consuming and makes the process lengthy. Stage 1 is completed before stage 2 begins.

The six stages involved in waterfall model are Requirement Gathering and analysis, System Design, Implementation, Integration and Testing, Deployment of system, and Maintenance.

Spiral model

This model is implemented in iterations. It is also called evolutionary model.

Initially a prototype of the system is prepared. Then, it is followed by development of small parts of the system.

These smaller parts are then assembled to produce the final system.

The four stages which form the spiral model are Identification, Design, Development and Evaluation and Risk Analysis.

The differences between the two models are summarized below.

1. Waterfall model works in linear method. Spiral model follows evolutionary method.

2. Errors and risks are discovered/ rectified after the stage is over. Errors and risks are discovered/ rectified earlier.

3. Waterfall model is suitable for small projects. Spiral model is suitable for large projects.

4. Requirements identification and planning is the initial stage in the waterfall model. Requirements identification and planning is done when needed, in the spiral model.

5. Waterfall model allows little to no flexibility in the system. Spiral model allows flexibility in the system.

6. Low flexibility makes the waterfall model more risky. High flexibility makes the spiral model less risky.

7. Waterfall model, overall, takes less time since requirements are clear. Spiral model is implemented when the requirements of the system are not clear and become clear through prototypes.

Think about how you view your emails—either the email service you use yourself or an email service you would choose to use. Desc

Answer:

and POP3, followed in later years. POP3 is still the current version of the protocol, though this is often shortened to just POP. While POP4 has been proposed, it's been dormant for a long time.

IMAP, or Internet Message Access Protocol, was designed in 1986. Instead of simply retrieving emails, it was created to allow remote access to emails stored on a remote server. The current version is IMAP4, though most interfaces don't include the number.

The primary difference is that POP downloads emails from the server for permanent local storage, while IMAP leaves them on the server while caching (temporarily storing) emails locally. In this way, IMAP is effectively a form of cloud storage.

What function would you use to calculate the total interest paid for the first year of a mortgage?.

WITCHER [35]

Answer:

To calculate the total interest paid for the first year of a mortgage, the formula M = [P.r (1+r)n] / [(1+r)n-1] × 12 can be used.

Define a function max_n(arr, n) that takes in an array and an integer as arguments. Your function will then return the n largest

NikAS [45]

Answer:

def max_n(arr, n):

arr.sort()

i = len(arr)-n

return arr[i:]

Explanation:

Define a function called max_n that takes two parameters, an array and an integer

Sort the array

In order to get the last n largest values, we need to slice the array. To do that we need a starting point. Our starting point of slicing will be the "lentgh of the array - n". That means, if we start slicing from that index to the last in the sorted array, we will get the last n largest values.

Assume array is 10, 2, 444, 91 initially.

When we sort it, it becomes 2, 10, 91, 444

Now let's say we want last 2 largest values, our sliced array index should start from 2 and go until the end

i = 4 - 2 = 2 → arr[2:] will return us 91 and 444
