The running time of Algorithm A is (1/4) n2+ 1300, and the running time of another Algorithm B for solving the same problem is 1
Mnenie [13.5K]

Answer:

Answer is explained below

Explanation:

The running time is measured in terms of complexity classes generally expressed in an upper bound notation called the big-Oh ( "O" ) notation. We need to find the upper bound to the running time of both the algorithms and then we may compare the worst case complexities, it is also important to note that the complexity analysis holds true (and valid) for large input sizes, so, for inputs with smaller sizes, an algorithm with higher complexity class may outperform the one with lower complexity class i.e, efficiency of an algorithm may vary in cases where input sizes are smaller & more efficient algorithm might be outperformed by the lesser efficient algorithms in those cases.

That's the reason why we consider inputs of larger sizes when comparing the complexity classes of the respective algorithms under consideration.

Now coming to our question for algorithm A, we have,

let F(n) = 1/4x² + 1300

So, we can tell the upper bound to the function O(F(x)) = g(x) = x2

Also for algorithm B, we have,

let F(x) = 112x - 8

So, we can tell the upper bound to the function O(F(x)) = g(x) = x

Clearly, algorithmic complexity of algorithm A > algorithmic complexity of algorithm B

Hence we can say that for sufficiently large inputs , algorithm B will be a better choice.

Now to find the exact location of the graph in which algorithmic complexity for algorithm B becomes lesser than

algorithm A.

We need to find the intersection point of the given two equations by solving them:

We have the 2 equations as follows:

y = F(x) = 1/4x² + 1300 __(1)

y = F(X) = 112x - 8 __(2)

Let's put the value of from (2) in (1)

=> 112x - 8 = 1/4x² + 1300

=> 112x - 0.25x² = 1308

=> 0.25x² - 112x + 1308 = 0

Solving, we have

=> x = (112 ± 106) / 0.5

=> x = 436, 12

We can obtain the value for y by putting x in any of the equation:

At x=12 , y= 1336

At x = 436 , y = 48824

So we have two intersections at point (12,1336) & (436, 48824)

So before first intersection, the

Function F(x) = 112x - 8 takes lower value before x=12

& F(x) = 1/4x² + 1300 takes lower value between (12, 436)

& F(x) = 112x - 8 again takes lower value after (436,∞)

Hence,

We should choose Algorithm B for input sizes lesser than 12

& Algorithm A for input sizes between (12,436)

& Algorithm B for input sizes greater than (436,∞)

Write a program to calculate student's average test scores and the grade. You may assume the following input data:
Brums [2.3K]

Answer:

def gradeAverage():

   grades = []

   i = 0

   while i < 5:

       a = int(input('enter score ' + str(i + 1) + ': '))

       grades.append(a)

       i = i+1

   #print(grades)

   average = sum(grades)/len(grades)

   #print(average)

   return average

def lettergrade(a):

   letter = 'A'

   if a < 60:

       letter = 'F'

   elif 59 < a < 63:

       letter = 'D-'

   elif 62 < a < 67:

       letter = 'D'

   elif 66 < a < 70:

       letter = 'D+'

   elif 69 < a < 73:

       letter = 'C-'

   elif 72 < a < 77:

       letter = 'C'

   elif 76 < a < 80:

       letter = 'C+'

   elif 79 < a < 83:

       letter = 'B-'

   elif 82 < a < 87:

       letter = 'B'

   elif 86 < a < 90:

       letter = 'B+'

   elif 89 < a < 94:

       letter = 'A-'

   elif 93 < a < 101:

       letter = 'A'

   return letter

numOfStudents = int(input('How many students: '))

names = []

aver = []

grade =[]

while numOfStudents > 0:

   studentName = input('Enter students name: ')

   names.append(studentName)

   a = gradeAverage()

   aver.append(a)

   grade.append(lettergrade(a))

   numOfStudents = numOfStudents - 1

for name in names:

       for score in aver:

           for letter in grade:

               if names.index(name) == aver.index(score) == grade.index(letter):

                   print('%s : Average =  %d  Letter Grade:  %s \n' %(name, score, letter))

                   break

Explanation:

The programming language used is python.

Two functions were created, the first function gradeAverage() was used to calculate the average values of the scores.

The second function lettergrade(a) was used to get the letter grade i.e(A, A-, C, D, e.t.c.) and it takes its argument from the average.

The main block of code asks for how many students are there and prompts the user to input their names and scores for all the students.

It takes that data calculates the average and the letter grade and prints out the names of the students, their average and their letter grade.

meriva

The thing that Katsumi should do in this situation is to option A in the image attached.

<h3>Why choose option A?</h3>

Note that Design documentation is said to be a composition of documents and resources that is said to cover all areas of one's product design.

Option A is correct because  in the above scenario, it is usually mostly inconclusive and as such, Katsumi  should do nothing.
