UML is a graphical language that is used for designing and documenting software created within the _____________ framework. (a)

stealth61 [152]

Answer:

The answer is "option d".

Explanation:

UML stands for Unified Modeling Language. It is an OOPs based language that is used to design a graphic by software developers. This language can also be used to build diagrams and provide some tools to ready-to-use, interactive templates for users and other options are not correct that can be described as:

In option a, The Top-down approach is not followed by UML.

In option b, UML uses an object-oriented programming language that follows a bottom-up approach. It refers to a style of programming.

In option c, It does not use structured programming because it uses procedural languages.

The divBySum method is intended to return the sum of all the elements in the int array parameter arr that are divisible by the i

iragen [17]

Answer:

The complete method is as follows:

public static int divBySum(int[] arr, int num){

int sum = 0;

for(int i:arr){

if(i%num == 0)

sum+=i;

}

return sum;

}

Explanation:

As instructed, the program assumes that arr has been declared and initialized. So, this solution only completes the divBySum method (the main method is not included)

This line defines the method

public static int divBySum(int[] arr, int num){

This line declares and initializes sum to 0

int sum = 0;

This uses for each to iterate through the array elements

for(int i:arr){

This checks if an array element is divisible by num (the second parameter)

if(i%num == 0)

If yes, sum is updated

sum+=i;

}

This returns the calculated sum

return sum;

}

g Boolean Algebraic properties _____. a. are used to make boolean expressions more complicated b. are used to convert a Boolean

vesna_86 [32]

Answer:

c. can lead to a simpler expression and thus a simpler circuit.

Explanation:

Boolean logic refers to a theory of mathematics developed by the prominent British mathematician, called George Boole. In Boolean logic, all variables are either true or false and are denoted by the number "1" or "0" respectively; True = 1 or False = 0.

Also, Boolean logic allow users to combine keywords with Boolean operators (quotes, AND, OR, near/n) to give a more personalized and relevant search results.

There are five (5) main Boolean Algebraic properties and these includes;

I. Commutative property: it applies to both multiplication and addition.

For addition; A + B = B + A
For multiplication; A.B = B.A

II. Associative property: it applies to both multiplication and addition.

For addition; A + (B + C) = (A + B) + C
For multiplication; A(BC) = (AB)C

III. Distributive property: it is formed using the product of a sum.

A(B + C) = AB + AC

IV. Complement property: it involves a variable and its complement.

For addition: A + A' = 1
For multiplication; A.A' = 0

V. Identity property:

For addition; A + 0 = A
For multiplication; A.1 = A

In digital electronics, Boolean expressions are used to represent circuits which comprises of Boolean operations and as such simplifying any logic expression without changing or altering any of it's functionalities and properties based on given operations or variables.

Hence, Boolean Algebraic properties can lead to a simpler expression and thus a simpler circuit.
