Answer:

Explanation:

Well, in your inquiry it says

"A presentation software that is used to organize and present pertinent information using graphics, word processing, outlining, drawing, and presentation management tools"

We know it isn't Microsoft Word, because Microsoft Word doesn't have a presentation feature. We know it isn't Excel because Excel is only meant for spreadsheet and analytics data.

However, on PowerPoint all these points make sense, PowerPoint is a tool that Microsoft created for the capabilities such as to present information, you can also put information inside of graphics as well, you can also draw, and outline too.

In 4-bit two's complement representation, what is the binary encoding of the number -5?

Katena32 [7]

Answer:

a) 1011

Explanation:

In 4 bit two's complement representation, the first bit is the sign bit.

If the sign bit is 1, the number is negative.

If the sign bit is 0, the number is positive.

What is the magnitude of the sign bit?

In n-bit two's complement representation, the magnitude of the sign bit is:

$2^{n-1}-1$

So, in 4-bit two's complement representation, the magnitude of the sign bit is:

$2^{4-1}-1 = 8$

Since the number is negative, the value of this bit is -8.

The other bits are magnitude bits, positive.

We have that the sum of these bits must be -5, and we already have -8. So what should be the value of these last 3 bits?

First, i am going to solve this equation to find the decimal value of the last three bits.

$-5 = -8 + x$

$x = 3$

So, the last three bits are:

$3_{10} = (011)_{2}$

The binary encoding of the number -5 is:

a) 1011

Assume the Student and Employee classes each extend the Person class. The Student class overrides the getMoney method in the Per

SSSSS [86.1K]

Answer:

Person p1, p2, p3;

int m1, m2, m3;

p1 = new Person();

// assignment 1

m1 = p1.getMoney();

p2 = new Student();

// assignment 2

m2 = p2.getMoney();

p3 = new Employee();

// assignment 3

m3 = p3.getMoney();

//////////////////////////////////////////////////////////////////////////////////////////////

The reference to getMoney in assignment 3 is to the <em>Person</em> class.

Explanation:

Since Employee class didn't override Person class's getMoney() method, calling p3 with getMoney() will call Base class's (Person) getMoney() method.
