Answer:

θ = 50 degrees

Step-by-step explanation:

we have sin θ = cos 40°

θ = arcsin ( cos 40°)

and make sure θ is less than 90 and greater than 0

θ = arcsin (0.766044443)

θ = 50 degrees

Answer: The required probability is 0.008.

Step-by-step explanation:

Since we have given that

Probability of bachelor's degree = 0.45

Probability of working in nursing = 0.85

Probability of both = 0.4

So, Probability of getting a graduate is currently working in nursing, given that they earned a bachelor's degree would be :

$P(N|B)=\dfrac{P(N\cap B)}{P(B)}\\\\P(N|B)=\dfrac{0.4}{0.45}\\\\P(N|B)=0.008$

Hence, the required probability is 0.008.
