Answer:
sin -115° = -0.91
Step-by-step explanation:
Point A is (cos 115°, sin 115°). Since cos 115° = -0.42 and sin 115° ≈ 0.91, it means that the coordinates at point A is (-0.42, 0.91).
As for point B which was revolved around -115°,
the coordinates will be similar to point A but you just have to change the negative.
B(cos -115°, sin -115°) = B(0.42, -0.91)
A, the relationship lasts over a given period of time.
Answer:
A) 12/37
B) 12/46
C) 25/54
D) 29/100
Step-by-step explanation:
Let event A = small-business owner selected economy,
event B = small-business owner selected finding qualified workers,
Thus, probabilities;
P(A)=46/100
P(B)=37/100
P(A∩B)=12/100
A) P(A ∩ B)/P(B) = (12/100)/(37/100) = 12/37
B) P(A∩B)/P(A) = (12/100)/(46/100)= 12/46
C) P(B∩A')= P(B) − P(A∩B) =
37/100 - 12/100 =25/100
P(B∩A')/P(A') =
(25/100)/(1-46/100) = 25/54
D) Using inclusion-exclusion principle;
P(A∪B) = P(A)+P(B)−P(A∩B)=
46/100 + 37/100 - 12/100 = 71/100
Hence, the probability that the owner believes neither that the economy is a challenge for growth nor that finding qualified workers is a challenge for growth is;
P( A' ∩ B') = 1 − P(A∪B)= 1− (71/100)= 29/100
