Question

The universal set, &, and set W are defined below.

{= {all integers}

W= {a : 3 <2<10}

Select all of the statements below that are true.

Answer 1

The statements that are true are;

4∈W

10∈W

Which statements are true?

Universal set, E = {all integers}

= {....-1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10....}

W = {x: 3 < x ≤ 10}

= {4, 5, 6, 7, 8, 9, 10}

∈ is a set term which means member of

∅ is a set term which means empty or null.

Check all statements:

A. 3∈W

False

B. 4∈W

True

C. 1∈W

False

D. 7.5∈W

False

E. 10∈W

True

F. W= ∅

False
