For non-disjoint and/or non-complete class hierarchy, which of the following statements are true when mapping from ER to relational model. (choose all that apply)
a) a table is created for each super class entity set according to normal entity set translation method.
b) primary key of the subclass table is used as primary key of the new table
c) primary key of the super class table is used as the primary key of the new table.
d) a table is created for each subclass entity set with a column for each of the attributes of that entity set plus one for each attributes of the primary key of the super class entity set

(a) The expected value of X is given by E(X) = n*p, where n is the number of trials and p is the probability of success. In this case, n = 4 (the number of people chosen) and p = 5/23 (the probability of choosing a computer science major). Therefore, E(X) = 4*(5/23) = 0.87.

(b) The variance of X is given by Var(X) = n*p*(1-p), where n is the number of trials, p is the probability of success, and 1-p is the probability of failure. In this case, n = 4, p = 5/23, and 1-p = 18/23. Therefore, Var(X) = 4*(5/23)*(18/23) = 0.67.

(c) The standard deviation of X is the square root of the variance of X. Therefore, the standard deviation of X is √Var(X) = √0.67 = 0.82.

The program to prompt the user for hours and rate per hour using input to compute gross pay is in explanation part.

The process of carrying out a specific computation through the design and construction of an executable computer program is known as computer programming.

Here's a Python program that prompts the user for hours and rate per hour, then calculates the gross pay:

hours = input("Enter hours: ")

rate = input("Enter rate per hour: ")

# convert the input strings to numbers

hours = float(hours)

rate = float(rate)

# calculate the gross pay

pay = hours * rate

print("Gross pay:", pay)

Thus, the program will output "Gross pay: 96.25".

Answer:

def difference(num1, num2):

   if num1 > num2:

       return num1 - num2

   else:

       return num2 - num1

Explanation:

Here's a Python function that calculates the absolute difference between two numbers without using the built-in abs() function:

def difference(num1, num2):

   if num1 > num2:

       return num1 - num2

   else:

       return num2 - num1

This function checks which number is larger, and then subtracts the smaller number from the larger number to get the absolute difference. Note that if the two numbers are equal, the function will return 0.

The following assertion "The logical equivalent of files, relations are three-dimensional tables that organize all data elements. The relational paradigm presents data in tabular form as expected "is WRONG.

The relational model (RM), first introduced by English computer scientist Edgar F. Codd in 1969, is a method for managing data that adheres to a structure and language consistent with first-order predicate logic.

All data is represented as tuples that are organized into relations.

A relational database is one that is set up using the relational model.

The relational model's goal is to offer a declarative method for specifying data and queries.

Users directly state what information the database contains and what information they want from it, and they delegate the description of data structures for storing the data and retrieval procedures for responding to queries to the database management system software.

Therefore, the following assertion "The logical equivalent of files, relations are three-dimensional tables that organize all data elements. The relational paradigm presents data in tabular form as expected "is WRONG.

A combination is a selection of r things made without regard to the order in which they were chosen from a collection of n items whereas a permutation is a choice of r things out of a set of n option where order for chosen objects are considered.

a: Ways to select 2 computers out of 10, we make use of the Combination formula as follows:

10C2== [10*9]/[1*2] = 45 or

nCr=(n!)/((r!)(n-r!))

nCr  =      number of combinations

n = total number of objects in the set

r = number of choosing objects from the set

10!/(10-2)! 2!

=10 9 8!/8!2!

=90/2

=45

So ther are 45 ways.

b: The probability that exactly 1 will be defective (from the selected 2)

First, we calculate the probability of a PC being defective (p) and probability of a PC not being defective (q)

From the given parameters; 2 out of 10 is detective;

So;

p=2/10

0.2

q=1-0.2=0.8

Solving further using binomial;

(a + b)n =nC0 an + nC1 an – 1 b1 + nC2 an – 2 b2 + ... 1  

n=2

For the probability that exactly 1 out of 2 will be defective, we make use of

=nC3pq^3

Substitute 2 for n, 0.2 for p and 0.8 for q

=0.03072

c: Probability that at least one is defective;

In probability, the opposite probability sums to 1;

Hence;

The probability that at least one is defective + Probability that at none is defective = 1

The probability that none is defective is calculated as thus; q^n

Substitute 2 for n and 0.8 for q

Probability is 0.64

Substitute 0.64 for the Probability that at none is defective

The probability that at least one is defective +0.64 = 1. So

Probability = 1 - 0.64

Probability = 0.36.

The right response is B. The initial value of j in the for loop header should be 2. The code appropriately initialises fibs[0] and fibs[1] to 1, since the first two elements of the Fibonacci sequence are both 1.

However, the for loop starts with j = 1 and attempts to calculate fibs[2] by summing fibs[0] and fibs[1], which yields the right result of 2. Although fibs[1] and [2] have already been calculated and saved in the array, the code tries to generate fibs[3] on the following iteration when j = 2. As a result, the value stored in fibs[3] and all succeeding items of the array is erroneous. Since fibs[0] and fibs[1] are already initialised with the right values, the for loop should begin with j = 2 in order to resolve this issue. The remainder of the Fibonacci sequence may now be accurately calculated and stored in the array by the loop. the following is the updated code segment: j++ for (int j = 2; j fibs.length; int fibs = new int[10]); fibs[0] = 1; fibs[1] = 1 Fibs[j] is equal to Fibs[j - 2] plus Fibs[j - 1];

Code is a set of rules that are used in information processing and communications to change data—such as a letter, phrase, sound, image, or gesture—into something else, usually secret, so that it can be sent through a communication channel or stored in a storage medium.

The development of language, which enabled people to verbally communicate what they were thinking, seeing, hearing, or feeling to others, is one early example. Speech, on the other hand, restricts expression to the distance a voice can travel and the audience to those present at the time of the speech. The development of writing, which transformed spoken language into visual symbols, led to an expansion of the capacity for communication across space and time.
