7 0

Answer:

n\geq8

Step-by-step explanation:

You add 4 to both sides to make n the only thing on one side. Then to make the answer look better you move n to the left side and flip the symbol because n changed sides.

4\leq n-4\\ 4+4\leq n-4+4\\ 8\leq n\\ n\geq 8

Which combination represents the empty set? motor ⋃ manual motor ⋃ bicycle motor ∩ manual motor ∩ bicycle
creativ13 [48]

The combination that denotes the empty set{∅} is motor ∩ bicycle.

<h3>What is a set theory?</h3>

Set theory is the mathematical study of well-defined groups of things called elements of the set.

In the given Venn diagram, the elements in the set of Motor, Manual, and Bicycle are as follows:

  • Motor = {8, 24}
  • Manual = {24, 32}
  • Bicycle = {44}
  • The union of motor and manual i.e. Motor ⋃ Manual = {24}

The combination that represents an empty set {∅} is the intersection that occurred between motor and bicycle and can be expressed as:

= motor ∩ bicycle

This is because there are no set elements overlapping between motor and bicycle, this makes it an empty set{∅}.
