Answer:
Sinx = 5/13
cosy = 5/13
cosy = sinx ; they both share a proportional relationship
Step-by-step explanation:
From the attached triangle, since the triangle is right angled, we can use trigonometric functions where ;
sinx° = opposite / hypotenuse
From Pythagoras ;
Hypotenuse = √(opposite² + adjacent²)
Hypotenus = √(12² + 5²)
Hypotenus = 13
Sin x° = opposite / hypotenus = 5 / 13
Sin x° = 5/13
Cos y = adjacent / hypotenus = 5 / 13
Hence,
sinx = cosy
Therefore, they both share a proportional relationship.
Answer:
1) 10.55%
2) 30.77%
Step-by-step explanation:
52/52•39/51•26/50•13/49 = 0.105498... ≈ 10.55%
100% chance you draw a unique card on the first draw
51 cards left of which 13(3) = 39 are unique suit for your second draw
50 cards left of which 13(2) = 26 are unique suit for your third draw
49 cards left of which 13(1) = 13 are unique suit for your forth draw.
Two balls are already green
