To demonstrate probabilities, a mathematics teacher had students draw marbles from a bag which contained 9 yellow marbles and 8 blue marbles. during class, the bag was dropped and 2 yellow marbles and 2 blue marbles were lost. tell whether the loss of marbles changes the probability of drawing a blue marble from the bag. if so, was the probability increase or decreased?

true

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

answer: i think you should do the math and pay attention in class : )
