Mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.

  • A linear pair is made up of two angles, and the sum of their measures is 180°.

<h3>What is the formula for linear pairs?</h3>
  • A two-variable linear equation of the form axe + by + c, with a, b, and c all being real numbers and not equal to zero.
  • The Transitive Property states that if all real numbers x, y, and z are equal, then x=z.
  • Substituting characteristics. If x=y, then x can be swapped to y in any equation or formula.
  • Mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.
  • A linear pair is made up of two angles, and the sum of their measures is 180°.
  • Line pairs can be congruent.
  • Adjacent angles are joined by a vertex.
  • Angles that are similar cross across.
  • A linear pairing is unnecessary.

Therefore, mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.

  • A linear pair is made up of two angles, and the sum of their measures is 180°.

Which conditional probabilities are correct? Check all
saveliy_v [14]

Answer:

Correct options:

P(D | F) =  6/34

P(E | D) = 7/25

P(F | E) = 8/18

Step-by-step explanation:

In the figure attached, the missing Venn diagram is shown.

P(D | F) = P(D ∩ F)/P(F) = (5+1)/(5+1+7+21) =  6/34

P(E | D) = P(E ∩ D)/P(D) = (6+1)/(6+1+5+13) = 7/25

P(D | E) = P(E ∩ D)/P(E) = (6+1)/(6+1+7+4) = 7/18

P(F | E) = P(E ∩ F)/P(E) = (7+1)/(6+1+7+4) = 8/18

P(E | F) = P(E ∩ F)/P(F) = (7+1)/(5+1+7+21) =8/34
