Carlos is studying human skin cells under a microscope during science class. He asks his teacher why cells are small. Which response does his teacher give him?

Answer:

B. Encryption.

Explanation:

Encryption encrypts data so that it can not be understood if/when it is intercepted by a third party between the sender and the recipient.

For example, if you're encrypting via the keyword vanilla, and then sending an email to Bob saying "Hi Bob", it would get encrypted as something like Vjh D5xx. The recipient would then use the keyword vanilla to decrypt this message so they can read it as Hi Bob. Anyone who intercepts this wouldn't have the keyword, and would just see incoherent letters, numbers, and symbols that they couldn't make heads or tails of.

Secure websites use technology that scrambles the information you send. This is known as, Encryption. So, the correct option is B.

Given that,

Secure websites use technology that scrambles the information you send.

Since, Secure websites use encryption technology to scramble the information you send, ensuring that it remains secure and protected during transmission.

Encryption involves the use of mathematical algorithms to transform data into an unreadable format, making it extremely difficult for unauthorized parties to access or understand the information.

This is a fundamental method used to safeguard sensitive data on the internet.

So, Option B is true.

Explanation:

For this program we'll need to know a couple concepts which are: while loops, user input, variables, converting strings to integers, and basic arithmetic operators, if statements, and the random module.

So let's first just declare the basic function, we can call this "main", or something a bit more descriptive, but for now I'll name it "main".

def main():

   # code will go here

main()

so now from here, we want to initialize some variables. We need to somehow keep track of how many they get correct and how many they've answered.

These two numbers may be the same, but at times they will be different from each other, so we'll need two variables. Let's just call the variable tracking how much have been answered as "answered" and the variable tracking how much are correct as "correct".

These two will initially be zero, since the user hasn't answered any questions or gotten any correct. So now we have the following code

def main():

   correct = 0

   answered  = 0

main()

Now let's use a while loop, which we break out of, once the user inputs zero. This may be a bit tricky if we use a condition since we'll have to ask for input before, so let's just use a while True loop, and then use an if statement to break out of it at the end of the loop.

Now we want to generate two numbers so we can use the random module. To access the functions from the random module you use the import statement which will look like this "import random". Now that you have access to these functions, we can use the randint function which generates random numbers between the two parameters you give it (including those end points). It says two digits, so let's use the endpoints 10 and 98, and I'll explain later why I'm limiting it to 98 and not 99.

The reason we want to limit it to 98 and not 99, is because it's possible for the two randomly generated numbers to be equal to each other, so the answer would be zero. This is a problem because the zero is used to quit the program. So what we can do in this case, is add one to one of the numbers, so they're no longer equal, but if they're equal to 99, then now we have a three digit number.

Now onto the user input for simplicitly, let's assume they enter valid input, all we have to do is store that input in a variable and convert it into an integer. We can immediately convert the input into an integer by surrounding the input by the int to convert it.

we of course want to display them the equation, and we can either do this through string concatenation or f-strings, but f-strings are a bit more easier to read.

So let's code this up:

import random

def main():

   correct = 0

   answered  = 0

   while True:

       num1 = random.randint(10, 98)

       num2 = random.randint(10, 98)

       if num1 == num2:
           num2 += 1

       userInput = int(input(f"{num1} - {num2}"))

main()

from here we first need to check if they entered zero and if so, break out of the loop. If they didn't enter zero, check if the userInput is equal to the actual answer and if it is, then add one to correct and finally add one to answered regardless of whether their answer is correct or not.

Outside the loop to display how much they got correct we can use an f-string just like we did previously. Since sometimes we'll get a non-terminating decimal, we can use the round function so it rounds to the nearest hundreth.

So let's code this up:

import random

def main():

   correct = 0

   answered  = 0

   while True:

       num1 = random.randint(10, 98)

       num2 = random.randint(10, 98)

       if num1 == num2: # the answer would be zero
           num2 += 1 # makes sure the answer isn't zero

       userInput = int(input(f"{num1} - {num2}"))

       if userInput == 0: # first check if they want to stop

           break

       if userInput == (num1 - num2):
           correct += 1

       answered += 1

   print(f"Correct: {correct}\nIncorrect: {answered - correct}\nPercent: {round(correct/answered, 2)}")

main()

and that should pretty much be it. The last line is just some formatting so it looks a bit better when displaying.

Intellectual Property Rights (IPR) are  the creative rights over an original piece of work, invention or even an idea behind a business can come under the purview of Intellectual Property Rights Act.

Implication if the intellectual property rights do not exist

1.  Less research and development as nobody would reap benefits generated by their innovations.

2. Cultural and art vitality as they would not be made more according to their original work.

3. Job losses and economic issues as IPR helps in boosting both of these factors.

4. Healthcare and treatment would be at lost because of less innovation of useful vaccines.

5. Less emergence of startups with unique ideas, decline in innovative trade and a race backwards.

Answer: 60% decrease

Explanation:

How to calculate percentage decrease:

Subtract starting value minus final value

Divide that amount by the absolute value of the starting value

Multiply by 100 to get percent decrease

If the percentage is negative, it means there was an increase and not an decrease.

Percentage Decrease Formula

You can use the percentage decrease formula for any percent decrease calculation:

Percentage Decrease=Starting Value−Final Value|Starting Value|×100

Example Problem: Percentage Decrease

You have a lamp with a 60-watt traditional light bulb. Your lamp uses 60 watts of electricity per hour. You're considering replacing the bulb with an LED light bulb that uses 8 watts of electricity per hour. What is the percentage decrease in the lamp's hourly energy use if you switch to an LED light bulb?

Percentage Decrease = [ (Starting Value - Final Value) / |Starting Value| ] × 100

60 - 8 = 52

52 / 60 = 0.8667

0.8667 × 100 = 86.67%

So if you switch to an LED light bulb your lamp will use 86.67% less energy per hour.

Related Calculators

Answer:

40%

Explanation:

Whenever we find "x" percent of a number, we simply multiply by "x/100", because "percent" just means "per 100".

We can divide the 2.5, by 100 to see how many "groups" of 100 are in 2.5, which gets us, 0.025.

Now we multiply this by some value, which will be our percent, to get "1"

So we have the equation: [tex]0.025 * x = 1[/tex]

Dividing both sides by 0.025 gives us: [tex]x=40[/tex]

so our percentage would be 40.

But generally whenever you solve these problems you convert the "percentage" to a "decimal" by dividing the percentage by 100.

So finding "x" percent of "a", can be calculated by: [tex]a*\frac{x}{100}[/tex]

and from here you would calculate the value with the givens.
