Which sparkline type is best for displaying trends in data changes over time?

What is the difference between (IF instructions & WHILE instructions ) 0 를 들 T !

lara31 [8.8K]

Answer:

While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.

If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.

The answer is letter e.

People is the component poses the very large ongoing security risk. It also can be a threat to the safety. People play an essential part in most operational systems and methods. Information, ability and mental outlook often determine the feature and quantity of system output. Just as a stereo requires the right component, high-performance business systems require the right fit of people to work.

Python: Write a program that prompts the user for a meal: breakfast, lunch, or dinner. Then using if statements and else stateme

Alexeev081 [22]

The program prompts user for the time of meal they will be having and a suggestion made on their behalf. The program is written in python 3 thus :

meal= input('your meal : ')

#prompts user to enter a meal type

if meal == 'breakfast' :

#check if it's breakfast

print('How about some Avocado')

elif meal == 'lunch' :

#checks if it's lunch

print('like some grapes?')

else:

print('would rice be ok?')

A sample run of the program is attached.

If a star system 30 parsecs distant is found to be broadcasting intelligent radio signals, then their news is already approximat

IrinaK [193]

Answer:

97.85 years, approximately.

Explanation:

Light travels at a constant speed of 186,000 mi/seg or 300,000km/seg accross the Universe (in vacuum conditions). Radio waves are also part of the electromagnetic spectrum, and they also travel at the same speed as Light does.

A light-year is a measure of the distance that Light travels during a year, that is, 5.88 trillion miles. Light travels the same distance per year because its speed is constant, and this is an excellent property that scientists take advantage to measure distances.

A parsec is 3.26 light-years (19 trillion miles), and (a very important datum to solve this question) one light-year is 0.306601 parsec, that is, in a year Light travels 0.306601 parsec at a constant speed. The same would happen with intelligent radio signals broadcasted from a distant star system.

So, considering all these facts, it is a matter of proportions to solve this question (mostly because speed of Light is constant):

$\frac{1 year}{0.306601 parsec} = \frac{X years}{30 parsecs}$

$x =\frac{1 year * 30 parsec}{0.306601 parsec}$

$x = \frac{30}{0.306601} years$

x = 97.84704 years or,

x = 97.85 years, approximately.

In other words, Light spends 97.85 years (terrestials) to travel 30 parsecs.

Likewise, radio waves travel at the same speed, so they spend the same years (97.85 years) travelling across the Universe to be finally detected by a radiotelescope located, for instance, here, in our planet.

Finally, the star system broadcasted intelligent radio signal with 'news' that are already approximately 97.85 years old'.

➪ How many types of Engineering are there in the world ? ⛄

aleksley [76]

There are mainly five types of engineers found in the world. Each of them has a different set of skills and knowledge concerning their relative field.

<h3>Who is called an Engineer?</h3>

An Engineer may be defined as an individual who formats, designs, modifies, and creates machinery or technical equipment like software programs, construction buildings, bridges, etc.

The five types of Engineers are as follows:

Civil Engineers.
Chemical Engineers.
Electrical Engineers.
Mechanical Engineers.
Computer Engineers.

Civil engineers deal with the construction of buildings, bridges dams, airports, etc. Chemical engineers are associated with developing the products such as medicines, petrochemicals, plastics, etc.

Electrical engineers design and develop the manufacturing of electrical equipment like navigation systems, radar, communication systems, electric motors, etc.

Mechanical engineers always maintain their focus on manufacturing power-producing and power-using machines like electric generators, gas turbines, refrigerators, air-conditioners, etc.

Computer engineers deal with designing, manufacturing, and examining all software operated within an institution's computer system.

All such types of engineers work in their respective fields for designing, and manufacturing products and their delivery which makes the life of an individual easy, efficient, and reliable.

Therefore, it is well described above.
