Answer:

Training data is used to fine-tune the algorithm’s parameters and evaluate how good the model is

Explanation:

The statement about datasets used in Machine Learning that is NOT true is "Training data is used to fine-tune algorithm’s parameters and evaluate how good the model is."

This is based on the fact that a Training dataset is a process in which a dataset model is trained for corresponding it essentially to fit the parameters.

Also, Testing the dataset is a process of examining the performance of the dataset. This refers to hidden data for which predictions are determined.

And Validation of dataset is a process in which results are verified to perfect the algorithm's details or parameters

Answer:

The function in Python is as follows:

def reverse(inputstr):  

   outputstr = ""

   for i in inputstr:

       outputstr = i + outputstr

   return outputstr

Explanation:

This defines the function

def reverse(inputstr):

This initializes the output string

   outputstr = ""

This iterates through the input string

   for i in inputstr:

This generates the output string by reversing the input string

       outputstr = i + outputstr

This returns the reversed string

   return outputstr

If we use a minus sign to make a negative number like -2. Then the following terms will be:

A calculation is a methodical, well-thought-out process. Calculating the solution to a math problem is the first type of calculation, for which you might use a calculator. The calculation also includes applying logic to a non-numerical issue.

Plus, minus, multiply, and divide are the basic signs used in math to calculate problems. These signs also change when come n contact with each other, like plus and minus are equal to minus.

Like here, 2 - -2. Minus and minus is plus, so two plus two is four.

2 + -2 = 0, here plus minus = minus, so two minus two is 0.

Therefore, the calculation for the given is

I believe the answer would be D. Data Reporting!

hope this helps! <3

Answer:

Correct Answer D:- DATA Reporting.

Explanation:

Data reporting is the collection and submission of data that leads to accurate ground-based analysis incorrect data reporting can lead to extremely informed decision-making using wrong evidence. Data reporting is not only about information but also about data collection.

The reporting of data may be an unbelievably difficult task. In order to achieve the job of counting every resident of a country, census bureaus can hire even hundreds of thousands of workers.

Data reporting is a step that translates raw information into information. It is not the data analysis that transforms data and information into insights. If data is not reported, the problem is known as underreporting the opposite is wrong.

The question is incomplete. The complete question is :

Holly the Hacker has a list of 100,000 common passwords. She wants to use this list to break into UNIX-like systems that use a password file with lines consisting of:

The user's ID in plaintext.

10 bits of randomly chosen "salt," in plaintext.

The user's password, concatenated with the salt, and then encrypted.

There are very many such systems around the world, and Holly plans to steal the password files from as many as she can. The average system has 50 users in its password file.

Holly wants to create a master list of the encrypted versions of all the 100,000 passwords on her list, encrypted with all possible salt values. To create this master list, approximately how many encryptions of a password-concatenated-with-salt would Holly have to perform?

A. 2 million

B. 5 million

C. 100 million

D. 1 million

Solution :

It is given that the hacker, Holly wants break into the  UNIX-like systems using 100,000 common passwords that she has on her list. The system has at an average of 50 users in the password files.

Therefore, to create a master list, Holly have to perform about 50 x 100,000 = 5,000,000 encryptions for the password concatenated-with-salt.

Thus the correct option is option (B).  5 million

d. RAID 6

Explanation:

RAID is a data storage technology that combines multiple physical disk drive components into a single logical unit. The functions of RAID is to provide performance and redundancy.

RAID 0 provides data stripping but it does not offer data stripping.

RAID 1 increases performance to about 2x but it limits the disk capacity to about 50%

RAID 5 provides redundancy and increased perfomance but it is limited to small disk drive.

RAID 6 also provides redundancy but it slows performance

RAID 10 increases performance and data protection.

RAID 6 is the best drive that offers redundancy over performance.

Explanation:

The following is written in Java. It creates a while loop that requests price from the user and goes adjusting the quantity and subtotal as more prices are added. If 0 is entered it breaks the loop and outputs the quantity, subtotal, tax, and grand total to the user.

class Brainly {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       int quantity = 0;

       double subtotal = 0;

       double tax, grandTotal;

       while (true) {

           System.out.println("Enter a price: ");

           double price = in.nextDouble();

           if (price == 0) {

               break;

           } else if (price > 0) {

               quantity += 1;

               subtotal += price;

           }

       }

       tax = subtotal * 0.075;

       grandTotal = subtotal + tax;

       System.out.println("Quantity: $" + quantity);

       System.out.println("Subtotal: $" + subtotal);

       System.out.println("Tax: $" + tax);

       System.out.println("GrandTotal: $" + grandTotal);

•Determine your IP address.

•Verify physical connectivity to the network.

•Check that you have a logical connection to the network.

•Find out what path network traffic takes to get to its destination.

Translate from DNS names to IP addresses.

Solution :

The function code is :

function newPriceTable = UpdatePriceTable(origPriceTable,changePrice, colNum)

newPriceTable = origPriceTable:

newpriceTable(:,colNum) = newPriceTable(:,colNum)+changePrice;

end

UpdatePriceTable ([19.99, 9.99; 14.99, 8.99;], [-1.00, -1.50] , 1)

ans = 18.9900      9.9900
