<u>Rational Numbers</u>
A rational number is any number that can be expressed as a fraction

for a and b any integer and b different from 0.
As a consequence, any number that cannot be expressed as a fraction or rational number is defined as an Irrational number.
Let's analyze each one of the given options

The first part of the number is indeed a rational number, but the second part is a square root whose result cannot be expressed as a rational, thus the number is not rational

The second part is an exact square root (resulting 4) but the first part is a known irrational number called pi. It's not possible to express pi as a fraction, thus the number is irrational

The square root of 121 is 11. It makes the whole number a sum of a rational number plus an integer, thus the given number is rational

As with the first number, the square root is not exact. The sum of a rational number plus an irrational number gives an irrational number.
Correct option:

Answer:
End points of the this segment are (9,1) and (2,3).
Step-by-step explanation:
The given function is
End points of the this segment are (1,9) and (3,2).
If a function is defined as
then
It means, we have to interchange x and y-coordinates of the end points.
So, end points of the this segment are (9,1) and (2,3).
Plot these point and join them by a line segment.

Answer:
A-75 and B-25
Step-by-step explanation:
Firstly, divide the 200 students by the amount of sections (8) and that gives you 25 a section. Since year 7 has 3 sections and year 9 has 1, 3(25)=75 and 25(1)=25.
