Answer:
The statements must be true are A , D , E
Step-by-step explanation:
* Lets explain the figure
- There is a triangle
- Its interior angles are x° , y° , z°
- The angle of measure w° is an exterior angle of the triangle at the
vertex whose measure is z°
- There a fact in the triangle is the measure of the exterior angle of a
triangle at one of its vertices is equal to the sum of the measures
of the two opposite interior angles to this vertex
∵ w° the measure of the exterior angle of the vertex whose measure
is z°
∵ x° , y° are the measures of the opposite interior angles of the angle
whose measure is z°
∴ w° = x° + y°
∴ w° > x°
∴ w° > y°
* Lets find the statements must be true
# w > x ⇒ A
# x + y = w ⇒ D
# w > y ⇒ E

Answer: 1/80</h3>
Reason:
Set A = {0,1,2,3,4,5,6,7,8,9}
Set B = {0,1,2,3,4,5,6,7}
The probability of getting a "2" from set A is 1/10 since there is one copy of "2" that we want out of ten values total.
The probability of getting a "2" from set B is 1/8 for similar reasoning. This time there are eight numbers in this set.
Multiply those fractions mentioned (1/10)*(1/8) = 1/80
This fraction converts to the exact decimal value of 0.0125, meaning there's exactly a 1.25% chance of getting "2" twice in a row.
You can put each into standard form to see whether they have the right value.
