Explanation

Sorting means arranging data based on specific criteria such as size, value, or quantity.

These criteria determine the order (ascending or descending) of the data.

Explanation

The use of Integrated Circuits (ICs) in the third generation made computers smaller, faster, and cheaper to produce.

This innovation significantly reduced manufacturing costs, making computers more affordable.

The third generation of computers (1964–1971) used Integrated Circuits (ICs) instead of transistors or vacuum tubes.

ICs greatly reduced the size, increased speed, and improved efficiency of computers.

Explanation

Retention rate measures the percentage of students who continue their education by progressing from one grade to the next in a given year.

It reflects student persistence and the school system’s ability to keep children in school over time.

Explanation

Given:

10 pipes fill the tank in 1 hour 40 minutes = 100 minutes

Let's find the rate of 1 pipe:

Rate of 10 pipes = 1 tank / 100 minutes

Rate of 1 pipe = 1 tank / (10 × 100) minutes

= 1 tank / 1000 minutes

Rate of 8 pipes = 8 tanks / 1000 minutes

= 1 tank / (1000 / 8) minutes

= 1 tank / 125 minutes

Explanation

Let's use the Pythagorean theorem:

Height of pole (perpendicular) = 12m

Length of string (hypotenuse) = 20m

Distance between foot of pole and end point of string (base) = √(hypotenuse² - perpendicular²)

= √(20² - 12²)

= √(400 - 144)

= √256

= 16m

Explanation

DEC VAX and IBM AS/400 are classic examples of minicomputers.

It is used widely in businesses and research during the 1970s–1990s.

They are mid-sized computers, more powerful than microcomputers but smaller than mainframes.

Explanation

Vaccination introduces weakened or inactive germs (antigens) into the body.

In response, the immune system produces antibodies to recognize and fight future infections.

Explanation

Noble gases like helium, neon, and argon are placed in Group VIII (Group 18 in modern IUPAC numbering).

They are inert.

They have a full outer electron shell.

It making them stable and unreactive.

Explanation

کتربیونت کا مطلب ہوتا ہے چیزوں کو کاٹ چھانٹ کر بدلنا یا حذف کرنا۔

یہ لفظ عموماً تحریر یا باتوں میں رد و بدل کے لیے استعمال ہوتا ہے۔

Explanation

Let's solve the equations:

1. x + y = 5

2. x - y = 3

Add both equations:

2x = 8

x = 4

Now, substitute x = 4 in equation (1):

4 + y = 5

y = 1

The solution is (4, 1).
