What do you think would happen to the average if you kept rolling the number cube over and over? The average would keep increasing. The average would keep decreasing. The average would approach a set value. The average would not follow any pattern.

step-by-step explanation:

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
