Answer:

Step-by-step explanation:

cos43=60/AC

AC=60/cos43=82.04

cos27=60/BC

BC=60/cos27=67.34

sin(90-43)/BC=sin(43+27)/AB

AB=BCsin70/sin47

AB=67.34sin70/sin47

AB=86.522

P=86.522+67.34+82.04

P=235.9m

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{∅}.

SOMEONE PLEASE HELP MEEEEE!!!!!
Yuki888 [10]

Answer:

total population of school = 1000

1000 - 450 males = 550 female students

550 - 200 females not in extra curriculars = 350 females in extra curriculars

350 + 90 males in extra curriculars = 440 total in extra curriculars

Circle A = 440

Circle B - overlap = 200 females not in extra curriculars

440 + 200 = 640

1000 - 640 = 370 students represented by the portion of the Venn diagram not in either circle
