blue marbles
y = yellow marbles
Sum = b+y
The <span>chance of a blue marble being drawn first is:
b / (b+y) = 0.55
</span>The <span>chance of a blue marble being drawn first then a yellow next is:
</span>b / (b+y) * y / (b+y-1) = 0.37
This can be solve easily by using a theorem of Bayes
0.37/0.55 = .67 or 67%
Answer:
Percentage increase.

Answer:
b
Step-by-step explanation:
Using the trigonometric identity
sin2x = 2sinxcosx
That is the angle on the right side is half the angle on the left, thus
sinΘ = 2sin(
Θ )cos(Θ ) → b
Answer:
This is an identity or infinite solutions
Step-by-step explanation:
10x - 12y = 22
5x - 6y = 11
-2(5x - 6y = 11 )
-10x + 12y = -22
10x - 12y = 22
0=0
Identity solution
