Answer:
1a) 0.03 = 3/100 = 3%
2b) 0.08 = 8/100 = 8%
3c) 0.4 = 4/100 =4%
4d) 3/90
5e) 4/90
Step-by-step explanation:
a, b, c we multiply the probability of each one green = 1/10 red = 3/10 blue = 4/10 yellow = 2/10
They are independant and they are replaced.
2a ) they are dependent as they are not replaced so before multiplying we see the total is reduced each turn. From 1/10 to 3/9 for green and red.
They mention independent as they stay independent per 2 picks.
Meaning red is dependant on green but yellow is not dependant on when we pick for red its only dependant for blue.
1 x 3 = 3 10x 9 = 90 = 3/90 green and red
2 x 4 = 8 10 x 9 = 90 = 4/90
Your answer should be 60%, but I'm not sure.

Answer:
x = 12
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
8 + 6x is an exterior angle of the triangle, thus
8 + 6x = 30 + 4x + 2 = 4x + 32 ( subtract 4x from both sides )
8 + 2x = 32 ( subtract 8 from both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Answer:
Step-by-step explanation:
3(1/6+2/9)+(-2)
3(7/18)+(-2)
*reduce 3 and 18
7/6-2
*take 7 subtract with 2
= -5/6
