Answer: Option D
D. $108
Step-by-step explanation:
We must calculate the expected cost per patient to use treatment method B.
The expected cost for a discrete random variable x is:

Where
is the cost associated with the probability 
In this case, the random variable x is represented by the cost of each treatment.
For treatment B there is a possibility that antibiotic 2 works, in that case the cost x would be $ 100 and 
There is also the possibility that it does not work, in this case the cost x would be $180 and the probability 
The expected cost is:

Answer:
Angle BCA = 90
Step-by-step explanation:
A triangle inscribed inside of a circle using the diameter as it's hypotenuse is a right triangle
Where the angle opposite of the hypotenuse ( or diameter ) is the right angle
Angle BCA is the angle opposite of the diameter
Hence BCA = 90
Where the coordinates of a points pedepend on the distance to the origin of the coordinate system and also depend on the angle, the coordinate system is a POLAR coordinate system.
