Let X and Y be jointly continuous random variables. Each of the parts below has an unfinished equality which can be completed with one of the following options: E[X], E[Y ], X, or Y. Some of these options might be used more than once, and others might not be used at all. After each equal sign, please indicate the appropriate option. For example, if the unfinished equality is Σ x P(X = x) = , then you would write E[X] after the equal sign. You do not need to justify your answer.

Regardless of the relationship between X and Y,
E[E[X |Y]] =

E[E[X | Y]]=E[X]

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
