Answer:
50%.
Step-by-step explanation:
Dado que hay 12 canicas en una bolsa y 6 de ellas son verdes, para determinar la probabilidad de que si se elige una canica al azar, esta sea verde, se debe realizar el siguiente cálculo:
6 / 12 = X
0.5 = X
0.5 = 50/100
50/100 = 50%
Así, hay un 50% de probabilidades de que, eligiendo una canica al azar dentro de la bolsa, la canica elegida sea verde.

Find the area of a sector, whose perimeter is 40 cm, and the radius is 8 cm.
Answer:
96 cm²
Step-by-step explanation:
From the question,
s = (2πr∅/360)+2r................. Equation 1
Where s = Perimeter of a sector, r = radius, ∅ = angle subtend by the sector at the center of the circle.
Given: s = 40 cm, r = 8 cm
Constant : π = 3.14.
Substitute into equation 1 and solve for ∅
40 = (2×8×3.14×∅/360)+(2×8)
40 = (50.24∅/360)+16
40-16 = 50.24∅/360
50.24∅/360 = 24
50.24∅ = 24×360
50.24∅ = 8640
∅ = 8640/50.24
∅ = 171.97°
Area of a sector (A') = ∅πr²/360
A' = 171.97×3.14×8²/360
A' = 95.997
A' ≈ 96 cm²

Answer:
Radius: R = 12 in
Diameter: D = 24 in
Circumference: C = 75.4in
Area: A = 452.39 in²
Step-by-step explanation:
Solutions:
Diameter d= 2r
D = 2 × 12
D = 24
Circumference
C = 2πr
C = 2 × π × 12
C = 24π
C = 75.3982237
Area:
A = πr²
A = π × 12²
A = 144π
A = 452.389342
Which words represent a positive number?
answer:'+' also means 'add'
It signifies a positive number, as described above, but it also means 'add' or 'plus'. For example 2+3 means 'two plus three' with a result of 5. Here, the plus-sign means addition. The same confusion happens with the minus ( – ) sign.

Answer:
B, 3 8/9
Step-by-step explanation:
It all comes down to equivalent fractions.
2 1/3 as an improper fraction is 7/3.
1 5/9 as an improper fraction is 14/9. 1/3 = 3/9.
With that being said 7 x 3 = 21 resulting in 21/9.
14/9 + 21/9 = 35/9.
35/9 as a mixed fraction is 3 8/9.
Both table A and Table B below represent linear relationships.
Based on the information in the tables, which statement is true?
Group of answer choices
Both Table A and Table B represent proportional relationships.
Table A represents a proportional relationship but Table B does not.
Neither Table A nor Table B represent a proportional relationship.
Table B represents a proportional relationship but Table A does not.
Answer:
Both represent a proportional relationship
Step-by-step explanation:
This is because when the independent variable in each table increases, the dependent variable increases as well, making the relationship proportional.

Makers of a new pain-relieving medication claim that it relieves chronic pain faster than the current top-selling pain reliever on the market. A
double-blind experiment was conducted in which 10 people who experience chronic pain were randomly selected to take either the new or the
current medication. Each of the 10 people recorded the time, in minutes, from taking the medication until pain relief. After an appropriate time
period, each of the 10 people took the other medication and recorded the time from taking the medication until pain relief. The medication each
person took first was randomly determined, and because both medications look the same, the people in the study did not know which medication
was taken first. The table below shows summary statistics for the results.
