Question

Indicate whether the following mathematical statements are true (T) or false (F)
1.1 The set = {2,3,5,7,9,11} is a set written using roster notation?
1.2 If = { }, then F is a set?
1.3 If two matrices A and B are conformable, then = ?
1.4 A matrix with ≠ 0 is invertible?
1.5 If : 4 = : 6 then : = 3: 2 ?

Answer 1

Given : Few Statements

To find : Which are True & which are False

Solution:

set = {2,3,5,7,9,11}

Roster notation is a list of elements, separated by commas, enclosed in curly braces.

Hence this is True

If = { }, then F is a set   - True     Null or Empty Set

two matrices A and B are conformable   then A = B    FALSE

number of columns of A = the number of rows of B.

1.4 A matrix with ≠ 0 is invertible  - TRUE

4 = : 6   then 3 : 2   TRUE
