If there are 18 people in your class and you want to divide the class into programming teams of 3
members, you can compute the number of different teams that can be arranged using this formula
(n!/r!(n−r)!).

Answers

Answer 1

Using a combination method to determine how many ways can 18 people be divided into programming teams of 3 members, the number of programming teams can be arranged in 816 ways.

What is Combination?

In mathematical model, a combination is a mathematical approach for calculating the number of potential arrangements in a set of things without taking the order arrangement of the items is into consideration.

It can be expressed by using the formula;

[tex]\mathbf{ _nC_r = \dfrac{n !}{ r!(n-r)! } }[/tex]

where:

[tex] \mathbf{ _nC_r = number \: of \: combinations \: \} }[/tex]n = total number of set objects = 18r = number of choosing objects = 3

[tex] \mathbf{ _nC_r = \dfrac{18!}{ 3!(18-3)! } }[/tex]

[tex]\mathbf{ _nC_r = \dfrac{18!}{ 3!(15)! } }[/tex]

[tex] \mathbf{ _nC_r = \dfrac{18 \times \: 17 \times \: 16 \times 15!}{ 3!(15)! } }[/tex]

[tex]\mathbf{ _nC_r = \dfrac{18 \times \: 17 \times \: 16 }{ 3 \times \: 2 \times 1} }[/tex]

= 816 ways

Which of the given assertion methods will return true for the code given below? Student student1 = new Student(); Student student2 = new Student(); Student student3 = student1;
The Student class is as follows.
public class Student{
private String name;
}
a. assertEquals(student1, student2);
b. assertEquals(student1, student3);
c. assertSame(student 1, student3);
d. assertSame(student1, student2);

Answers

Answer:

The true statements are :

A. assertEquals(student1,student2)  

C. assertSame(student1,student3)

Explanation:

AssertEquals() asserts that the objects are equal, but assertSame() asserts that the passed two objects refer to the same object or not, if found same they return true, else return false.

Methods are collections of named code segments that are executed when evoked

The assertion method that will return true for the given code is: assertEquals(student1,student2)  

The code segment is given as:

Student student1 = new Student();

Student student2 = new Student();

Student student3 = student1;

In Java, the assertEquals() method returns true if two objects have equal values.

Assume student1 and student2 have equal values, the statement assertEquals(student1,student2) will return true

Answers

Answer:

The answer is "Option b".

Explanation:

Function chaining is shown by this code, as the functions are called one after the other with one statement. Whenever you want to call a series of methods through an object, that technique is beneficial. Just because of that, you may give the same effect with less code and have a single given value only at top of the leash of operations.

What is indirect program memory addressing? Explain the working of the following instructions?

a) JMP AX
b) JMP LIST[DX]
c) JMP NEAR PTR[DI+3]

Answers

Indirect main memory addressing is described as the method in which the variable's address is stored in a mind register and also a command is utilized to point towards the memory registers which hold the register. Instruction is used to direct towards a register that displays the results of the variables. The register, in turn, refers to that variable's address in simplistic words. As just a result, it is indeed considered a passive program, memory address.

The instructions operate as follows:

a)

JMP AX :

The JMP instruction is being used to execute an unconditional jump.AX is indeed the label's name. JMP AX codes are being used to transfer control of the flow program to the AX label.

b)

JMP LIST:

The JMP command can be used to execute an unconditional jump, JMP LIST[DX] is the label's name.  The JMP LIST[DX] program is being used to transfer control of its flow programs to the specified section. It is the segment to which the flow control is transmitted.

c)

JMP NEAR PTR[DI+3]: 

Unconditional jumps could be done with the JMP command as you'll see, the label is JMP NEAR PTR[DI+3]. It's being used to transmit flow control to a particular section, throughout this case [DI+3]. The close keyword indicates that perhaps the code segment would be in the line of code being nearby.

The probabilities for each color are to be as follows: white 30%, blue 10%, green 60%. Suggestion: Generate a random integer between 0 and 9. If the resulting integer falls in the range 0 to 2 (inclusive), choose white. If the integer equals to 3, choose blue. If the integer falls in the range 4 to 9 (inclusive), choose green. Test your program by running it ten times, each time observing whether the distribution of line colors appears to match the required probabilities.

Write a program that creates an an array large enough to hold 200 test scores between 55 and 99. Use a Random Number to populate the array.Then do the following:1) Sort scores in ascending order.2) List your scores in rows of ten(10) values.3) Calculate the Mean for the distribution.4) Calculate the Variance for the distribution.5) Calculate the Median for the distribution.

Answers

Answer:

Explanation:

The following code is written in Python. It uses the numpy import to calculate all of the necessary values as requested in the question and the random import to generate random test scores. Once the array is populated using a for loop with random integers, the array is sorted and the Mean, Variance, and Median are calculated. Finally The sorted array is printed along with all the calculations. The program has been tested and the output can be seen below.

from random import randint

import numpy as np

test_scores = []

for x in range(200):

   test_scores.append(randint(55, 99))

sorted_test_scores = sorted(test_scores)

count = 0

print("Scores in Rows of 10: ", end="\n")

for score in sorted_test_scores:

   if count < 10:

       print(str(score), end= " ")

       count += 1

   else:

       print('\n' + str(score), end= " ")

       count = 1

mean = np.mean(sorted_test_scores)

variance = np.var(sorted_test_scores, dtype = np.float64)

median = np.median(sorted_test_scores)

print("\n")

print("Mean: " + str(mean), end="\n")

print("Variance: " + str(variance), end="\n")

print("Median: " + str(median), end="\n")
