Write the following sets in roster form:

(i) A = {x : x is an integer and –3 ≤ x < 7}

(ii) B = {x : x is a natural number less than 6}

(iii) C = {x : x is a two-digit natural number such that the sum of its digits is 8}

(iv) D = {x : x is a prime number which is divisor of 60}

(v) E = The set of all letters in the word TRIGONOMETRY

(vi) F = The set of all letters in the word BETTER​

Answer 1

Answer:

A = { -3 , -2 , -1 , 0 , 1 , 2 , 3 , 4 , 5 , 6 }

B = { 1 , 2 , 3 , 4 , 5 }

C = { 17 , 26 , 35 , 44 , 53 , 62 , 71 , 80 }

D = { 2 , 3 , 5 }

E = { T , R , I , G , N , O , M , E , Y }

F = { B , E , T , R }
