Answer: pr (blue) = 1/3 or 0.33
Pr(green without replacement) = 1/2 = 0.5
Step-by-step explanation:
Probability = number of possible outcomes/ number of total outcomes
Total number of outcomes is the sum of all the marbles, given as 9
Pr ( first marble blue) = no of blue marbles/ total number of marbles
= 3/9 = 1/3 or 0.333
Second marble is chosen without replacement- this means that the total outcome has reduced by 1, total number of marbles has reduced to 8 because there was no replacement.
Pr (second marble is green) = number of green marble/ total number of marbles without replacing the first marble
= 4/8 = 1/2 = 0.5
I hope this helps.
X/2-y/3=3/2
(6×x/2)-(6×y/3)=6×3/2
3x-2y=9______(1)
x/3+y/2=16/3

Answer:
Step-by-step explanation:
The area of the big triangle is 1/2 b h = 1/2*6*(12^2 = 6^2 + x^2)
that ends up being 
the small triangle are needs to be subtracted....
that is the length of the unknown side...
1/2 B * h of that triangle get you to 
just subtract the two areas
Answer:
2z+6 or 2(z+3) are the equivalent expressions
Step-by-step explanation:
z+(z+6)
opening the brackets
z+z+6
=2z+6
or if we take 2 as common the answer is
=2(z+3)
i hope this will help you :)
