Which statements are true about x? select three options

The true statements about x are:

x ∈ B ∪ C

x ∈ B ∩ C

x ∈ A ∪ C

A set is a clearly defined collection of objects.

To declare a set can be done in various ways such as:

Multiplying set A x B is by pairing each member of set A with each member of set B.

Example:

A = {1, 2, 3}

B = {a, b}

Then

A x B = {(1, a), (1, b), (2, a), (2, b), (3, a), (3, b)}

Union of set A and B ( A ∪ B ) is rewriting each member A and combined with each member B.

Intersection of set A and B ( A ∩ B ) is to find the members that are both in Set A and Set B.

Example:

A = {1, 2, 3, 4}

B = {3, 4, 5}

A ∪ B = {1, 2, 3, 4, 5}

A ∩ B = {3, 4}

Let us now tackle the problem!

To solve this problem, it is better to draw the Venn diagram as shown in the picture in the attachment.

Let :

A = { p , q , s , t }

B = { q , r , t , x }

C = { s , t , v , x }

From the results above, it can be concluded that the correct statements are:

x ∈ B ∪ C

x ∈ B ∩ C

x ∈ A ∪ C

The first three options

Step-by-step explanation:

Took the test

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
