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:
i really dont know
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = (x + 5)(x - 5)
= x² - 5²
= x² - 25
Degree of this polynomial is 2.
Highest power of the variable x will be the degree of the polynomial.
Answer:
175
Step-by-step explanation:
Find how much is left by multiplying 200 by 0.875, since this will give you the remaining 87.5%:
200(0.875)
= 175
So, the answer is 175.
