Helene is doing a probability experiment. she picks a marble from a bag without looking. she writes down the marbles color in the table. then she puts the marbles back into the bags. the table shows her data.

color | number of times picked

| red | 15 |

| blue | 6 |

| green | 12 |

| black | 20

| yellow | 7 |

based on the data in the table what is the probability that helene will pick a green marble next?

a.4/5

b.3/4

c.1/5

d.1/10

e.1/12

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: it's upside down and i can't read it

step-by-step explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

the answer is 13/48
