The difficulties with the k-nearest neighbor algorithm is option c. none of the above.

<h3>What problems does the K-nearest Neighbor algorithm have?</h3>

An unlabelled point is given a label based on its proximity to all other nearby labelled points. This is how it works. Its main drawbacks are that picking the "right" value of K is challenging and that it is highly computationally inefficient.

Hence, The supervised machine learning technique known as the k-nearest neighbors (KNN) can be used to tackle classification and regression issues. It is simple to use and comprehend, but it has the important problem of becoming noticeably slower as the amount of data in use increases.

What is a general term for a type of database which is endlessly and easily scalable without a measurable performance decrease
Andrews [41]

Answer:

<u>Scalable database</u>

Explanation:

Good examples of a scalable database include; NoSQL database, MySQL, Microsoft SQL.

<em>Remember</em>, these databases are called scalable databases because they support memory expansion without a measurable performance decrease.

For example, if the management of a hotel notices that its 1 terabyte computer used to store its security videos is no longer adequate to meet the hotel's expansion, then decide to buy a newer server that can be integrated into the current system. We can say they just applied the concept of scalable databases.

Based on three scores that the user inputs, display the average of the score and the letter grade that is assigned fort he test
Korolek [52]

I used python function to write the code.

def averageScore(x,y,z):

    s = x + y + z

    avg = s/3

   if avg >= 90:

              return f'Your average test score is {avg} You earned a A.'

    elif avg >=80 and avg < 90 :

                return f'Your average test score is {avg} You earned a B.'

   elif avg >=70 and avg < 80 :

                 return f'Your average test score is {avg} You earned a .C'

      elif avg >=60 and avg < 70 :

                  return f'Your average test score is {avg} You earned a D.'

      else:

                    return f'Your average test score is {avg} You earned a F.'

print(averageScore(98, 90, 80))

Python function is used to write the code where x, y and z are the argument (user inputs) of the function. Then the inputs are summed and the average is gotten and stored with the variable, avg.  

If the average is greater than or equal to 90 the program will give the appropriate score and response(grade). It does the same if the user scored 80 - 89, 70 - 79, 60 - 69 and less than 60.

Finally. the function is called with the user input(argument).

Note the bolded values in the code are keywords in python.
