Since you provide no options,

the correct venn diagram would  represent

- 2 circle intersect with one another
- 14 will be written on left circle
- 8 written on right circle
- 6 written on intersection
- 2 written outside the circle

hope this helps

Answer:

Step-by-step explanation:

Given :

Total students = 30

Students passed chemistry exam = 20

Students passed physics exam = 14

Students passed both exams = 6

To find: Venn diagram

Solution:

Total students = 30 i.e. U = 30

Students passed chemistry exam = 20

Students passed physics exam = 14

Students passed both exams = 6

Students passed only chemistry = 20-6 =14

Students passed only Physics = 14-6=6

So refer the attached figure for the Venn diagram

Which equation represents the function represented by the table? 17 POINTS!!!
dybincka [34]

Answer:

  f(x) = -x -1

Step-by-step explanation:

You can make the correct choice by seeing which equation works for the first line of the table.

  f(-1) = -(-1) -1 = 0 . . . . . the first equation works

  f(-1) = -(-1) +1 = 2 . . . not zero

  f(-1) = -1 -1 = -2 . . . not zero

  f(-1) = 1 -(-1) = 2 . . . not zero (same as second equation)

How many diagonals can be drawn from each vertex of a 15-gon?
tangare [24]

Answer:

Correct option: third one -> 12

Step-by-step explanation:

In a polygon with 'n' vertex, we can trace diagonals from one vertex to all vertices, except to the vertex chosen and the two adjacent vertices (because we would have sides and not diagonals), so we would have 'n - 3' diagonals.

If we have a polygon with 15 vertex, the number of diagonals from one vertex is 15 - 3 = 12.

Correct option: third one

#12 with explanation please
4vir4ik [10]

Answer:

  • 30.01 units

Step-by-step explanation:

<u>Given vertices WXYZ:</u>

  • W(-4,5), X(2,4), Y(3, -4), Z(-1, -6)

Perimeter is the sum of the side length.

<u>Use distance formula to find each side:</u>

  • WX = \sqrt{(2+4)^2+(4-5)^2} =\sqrt{37} ≈ 6.08
  • XY = \sqrt{(3-2)^2+(-4-4)^2} =\sqrt{65} ≈ 8.06
  • YZ = \sqrt{(-1-3)^2+(-6+4)^2} =\sqrt{20} ≈ 4.47
  • WZ = \sqrt{(-1+4)^2+(-6-5)^2} =\sqrt{130}\sqrt{(-1+4)^2+(-6-5)^2}=\sqrt{130} ≈ 11.40

<u>Find perimeter:</u>

  • P = 6.08 + 8.06 + 4.47 + 11.40 = 30.01 units
