A bag contains 7 red marbles, 8 blue marbles, and 9 green marbles. What is the probability of choosing a blue marble when one marble is drawn?

The probability of choosing a blue marble is 1/3.

Step-by-step explanation:

Add up all of the marbles.

7+8+9=24.

Next, you get the fraction of the chosen marble type over all marbles. In this case, it's blue, so it's 8/24

Finally, you must simplify the fraction.

1/3 is the simplest form of 8/24.

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
