40.9267 is the square root
Answer: The answer is 80%.
Step-by-step explanation: Let us define the following events.
B = the event that the shirt is blue,
G = the event that the shirt is green
and
S = the event that the shirt is striped.
So, n(B) = 8, n(G) = 7, n(B and S) = 5, n(G and S) = 4.
n(S) = 5 + 4 = 9.
We have

Therefore, the required probability is

Thus, the answer is 80%.
Angle x° and angle
154° are supplementary angles, meaning that they equal 180° when added.
Answer: 0.6 in 10 % ; 0.4 in 15 %
Step-by-step explanation:
1. (x*10%) + (y*15%)/ x+y=12%
2. x+y = 1 x= 1-y
(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y
-2x=-3y
2x = 3y 2(1 - y)= 3y
2-2y=3y 2= 5y
y= 0.4
x= 0.6
