Are the triangles congrouent? if so which postulate are the congrouent by?

ankoles [38]

Answer:

ASA

Step-by-step explanation:

They give us one pair of angles and one pair of congruent sides for it to be ASA we need an additional angle but on the other side from where the last angle was. By vertical angles proof we can see that the angles at the intersection will be congruent so you have one angle then a side then another angle

Suppose you roll n ≥ 1 fair dice. Let X be the random variable for the sum of their values, and let Y be the random variable for

noname [10]

Answer:

X and Y are stochastically dependent RVs .

Step-by-step explanation:

Let ,

X = sum of the values that come up after throwing n (≥ 1) fare dice.

Y = number of times an odd number come up.

Let, n = 3

then, P(X =6) = p (say) clearly 0 < p < 1

and P (Y = 3) = $\frac{1}{8}$

And,

P( X = 6, Y = 3) = 0 ≠ $P(X = 6) \times P(Y= 3)$

Hence, X and Y are stochastically dependent RVs
