Part 3) {L, M, N, P, Q, R, S, T, V, W,X,Y, Z}
Step-by-step explanation:
Part 1) List the elements of the set
x is an integer for the interval (-1/2,9/2)
Remember that
-1/2=-0.5
9/2=4.5
so
we know that
The integers in the given interval are
(-0.5,4.5)
therefore
The elements of the set are
{0,1,2,3,4}
Part 2) List the elements of the set
x is an month of the year which does not contain 31 days
The months which not contains 31 days are
February, April, June,September, November
therefore
The elements of the set are
{February, April, June,September, November}
Part 3) List the elements of the set
x is a consonant of English alphabet which comes before k
we know that
The 21 consonant letters in the English alphabet are
B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W,X,Y, Z
so
The consonant of English alphabet which comes before k are
L, M, N, P, Q, R, S, T, V, W,X,Y, Z
therefore
The elements of the set are
{L, M, N, P, Q, R, S, T, V, W,X,Y, Z}
