Answer:

If two parallel lines  p and q are cut by a transversal, then the alternate interior angles are congruent.

Below is the prove of this.

Step-by-step explanation:

As we know that Alternate interior angles are two angles that are on the interior of p and q, but on opposite sides of the transversal.

In other words,  If two parallel lines  p and q are cut by a transversal, then the alternate interior angles are congruent.

Lets prove this.

Given: p ║ q

Prove: ∠1 ≅ ∠2

Statement                                  Reasons

1. p ║ q                                        1. Given

2. ∠1 ≅ ∠3                                  2. Corresponding Angles Postulate

3. ∠3 ≅ ∠2                                 3. Vertical Angles Congruence Theorem

4. ∠1 ≅ ∠2                                  4. Transitive Property of Congruence

vitfil [10]

Answer:

Step-by-step explanation:

Given that if an odd number comes up, you lose.

i.e. P(losing) = P(1,3,5) = \frac{1}{2}

P(win 60) = P(6) =\frac{1}{6} \\

If you get 2 or 4 you roll again

Thus rolling again prob = \frac{2}{6} =\frac{1}{3}

After rolling II time, if get 6, win otherwise lose.

Thus winning amounts A canbe

0     36   60

P(0) = \frac{1}{2}+\frac{1}{3} (\frac{5}{6})=\frac{7}{9}  \\P(36) = \frac{1}{3} (\frac{1}{6})=\frac{1}{18}\\P(60) =\frac{1}{6}

This is a genuine pdf since prob >0 and total prob = 1.

b)Expected gain = sum of gain * prob = \frac{7}{9} (0)+\frac{1}{18} (36)+\frac{1}{6} (60)\\=12

Thus I would be willing to pay an amount atmost 12 dollars.
