The true statement is the report is grouped only because it gives information about employees by number of years of employment.

<h3>What is a group report?</h3>

When designing a suitable and safe flexibility training program, you should set reasonable and appropriate goals depending on wh

GalinKa [24]

Answer:

The following steps will help you design a safe and effective stretching program.

Explanation:

1. You will have to follow the ACSM's guidelines used for flexibility training.

2. evaluate your flexibility rate with the "sit-and-reach" test.

3. you have to also apply the basic principles of FITT in designing your own program.

4. have a "range-of-motion" tests performance.

5. make use of SMART guidelines when setting explicit flexibility goals.

Write a program to sort the (name, age, score) tuples by descending order where name is string, age and score are numbers. The s

zimovet [89]

Answer:

The program in Python is as follows:

from operator import itemgetter

m = int(input("Number of records: "))

print("Name, Age, Score")

my_list =[]

for i in range(m):

user_details = input()

my_list.append(tuple((user_details.split(","))))

my_list.sort(key = itemgetter(0, 1, 2))

print("Sorted: ", my_list)

Explanation:

This imports the operator function from itemgetter

from operator import itemgetter

This gets the number of records, m

m = int(input("Number of records: "))

This prints the format of input

print("Name, Age, Score")

This initializes the list of tuples

my_list =[]

This iterates through m

for i in range(m):

This gets the details of each person

user_details = input()

This appends the details to the tuple

my_list.append(tuple((user_details.split(","))))

This sorts the tuple

my_list.sort(key = itemgetter(0, 1, 2))

This prints the sorted tuple

print("Sorted: ", my_list)

Write a Scheme function called "sum" which takes an input function func and a nonnegative number n and outputs the value

solong [7]

Answer:

function sum(number) {

if (number == 1) {

return 1;

}

return number + sum(number -1);

}

Explanation:

This is a recursive function, it means that is a function that calls itself for example: if you call the function with sum(5) the process is :

sum(5)

|______ 5 + sum(4)

|_______ 4 + sum(3)

|______ 3 + sum(2)

|_____2 + sum(1)

|_____ 1

the result is 1+2+3+4+5 = 15

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.
