The probability that a six sided number cube lands on a 5 is 1/6. Predict the number of times the cube will land on a 5 if the cube is tossed 72 times.

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

5x+10 is the correct one

hope this
