•you roll two standard number cubes.
what is the probability of rolling a 3 on
one cube, but not both cubes?

5/18

Step-by-step explanation:

There are two ways this can happen: you roll a 3 on the first cube and not a 3 on the second cube, or you roll not a 3 on the first cube and 3 on the second cube.

P = (1/6)(5/6) + (5/6)(1/6)

P = 5/36 + 5/36

P = 10/36

P = 5/18

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
