Identify which of the following statement(s) is always true?

julia-pushkina [17]

Answer:

Statement 3

Step-by-step explanation:

Statement 1: For any positive integer n, the square root of n is irrational.

Suppose n = 25 (25 is positive integer), then

$\sqrt{n}=\sqrt{25}=5$

Since 5 is rational number, this statement is false.

Statement 2: If n is a positive integer, the square root of n is rational.

Suppose n = 8 (8 is positive integer), then

$\sqrt{n}=\sqrt{8}=2\sqrt{2}$

Since $2\sqrt{2}$ is irrational number, this statement is false.

Statement 3: If n is a positive integer, the square root of n is rational if and only if n is a perfect square.

If n is a positive integer and square root of n is rational, then n is a perfect square.

If n is a positive integer and n is a perfect square, then square root of n is a rational number.

This statement is true.

A freelance computer consultant keeps a database of her clients, which contains the names S = {Acme, Bakers, Cores, Dual, Energy

DaniilM [7]

We want clients that do not owe her money or have employed her in the last year. In set terminology, the or operator is represented by the union of two sets.

So, we're looking for the union between the subsets of clients that don't owe money and clients that have employes in the last year.

The first subset is A', because we're looking for the negation of its condition.

The second subset, by definition, is exactly C.

So, the answer is A' ∪ C.

To list the customer, we have:

A' = {Bakers, Dual, Flavour, Hilbert}

C = {Acme, Cores, Dual, Energy, Global, Hilbert}

So, their union is composed by all elements belonging to A' or E (or both), without repetitions:

A' ∪ C = {Acme, Bakers, Cores, Dual, Energy, Flavour, Global, Hilbert} = S
