Answer:
A
Step-by-step explanation:
The diagram shows two parallel lines XY and WV.
1. Parallel lines XY and WV are cut by transversal XW, then angles YXZ and VWZ are congruent as alternate interior angles.
2. Parallel lines XY and WV are cut by transversal YV, then angles XYZ and WVZ are congruent as alternate interior angles.
AA similarity theorem states if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
So, by AA similarity
Answer:
Step-by-step explanation:
Let M denote the event that the stock makes money and D denote the event that the stock pays dividends.
It is given that
Observe that the two events M and D are not independent because if the stock doesn't make money then it will not pay dividends. Therefore the event (D given M does not occur) is a null event, i.e
It is also given that,
Recall that :
Here, we are required to find
