c be an irrational number.
A
eet the appropriate cell in the table to show whether each value is always . jonal, never rational, or sometimes rational.




Value

a+b

a-b

c^(2)


Always Rational

a+




Never Rational





Sometimes Rational







Part B
Consider a quadratic equation with integer coefficients and two distinct zeros. If one zero is irrational, which statement is true about the other zero?

Cross-toplc
36. A shopkeeper holds a luoky draw in which a player has to pay 
$30 for drawing a sticker at random from a box. There are. 80 stickers in the box where a logo (star/heart/cress) is printed on each sticker. The prize for each logo is listed as follows:




Logo on the sticker drawn
star
heart
cross


Prize
a pencil case of value 
$00
a backpack of value 
$300^(')
। no prize




It is known that there are 5 stickers with a heart in the box. If the game is favourable to the shopkeeper, at most how many stickers with a star are there in the box?

A test paper consists of multiple choice questions. Each question has 4 options and only one option is correct. The rules arc as follows:
For each question. 4 marks will be awarded for a correct answer; 2 marks will be deducted for an incorrect answer and 1 mark will be deducted for no answer.
Victor has no idea about the answers of the test.
(a) Find the expected value of the marks that Victor gets in a question if he answers the question by wild guessing.
(b) Which method will be better for Victor to obtain higher marks: answering all the questions by wild guessing or answering none of the questions? Explain your answer.
(Assume the answer chosen for a question is not affected by the answers chosen for other questions.)
