A - drawing a girls name at first
P(A) = 2/(2+9) = 2/11
B - drawing a boys name in second drawing if first drawing was a girls name
P(B) = 9/10
C - drawing a girls name firstly and a boys name secondly
P(C) = P(A) * P(B) = 2/11 * 9/10 = 9/55
ans: 9/55

Answer:
Step-by-step explanation:
To find how many solutions that they have, we must set both equations equal to each other as such:
-3x = -3x + 1
0 = 1, which isn't true
The system has zero solutions, I know this because when I solve the system of equation, I get that 0 =1 which isn't true
Hope that helps!

Answer:
∠Z ≈ 12°
Step-by-step explanation:
Using the Sine Rule in ΔXYZ
= 
, that is
= 
( cross- multiply )
48 × sinZ = 10 × sin96° ( divide both sides by 48 )
sinZ = 
Z = 
( ) ≈ 12°
