Two different chemotherapy regimens can be used to treat breast cancer. treatment with doxorubicin is known to show a remission rate 40% of the time. this treatment costs $1,000. the other treatment, docetaxel, shows a remission rate 25% of the time and costs $850.
the two treatment plans are:
plan a: treat with doxorubicin. if not effective, treat with docetaxel.
plan b: treat with docetaxel. if not effective, treat with doxorubicin.
based on the data provided, what is the expected cost per patient under plan b?
the answer choices are: $850, $1000, $1,510, or $1,600

Expected Cost under PLAN B = $1600

So, Option D. $1600 is correct

Step-by-step explanation:

Cost of first treatment (docetaxel) whether it is effective or not = $850

Cost of second treatment (doxorubicin) whether it is effective or not = $1000

But The Plan B says, if the first treatment is effective then second treatment is not needed

Now, chance that the first treatment is effective = 25%

So, chance that the first treatment is not effective and you need the second treatment = 75%  

P(first treatment is effective) = 0.25  

Cost(if first treatment is effective) = $850  

P(first treatment is not effective) = 0.75  

Cost(if first treatment is not effective) = 850 + 1,000 = $1850  

Expected cost = P(first treatment is effective) × Cost(if first treatment is effective) + P(first treatment is not effective) × Cost(if first treatment is not effective)  

Expected cost = (0.25 × 850) + (0.75 × 1,850)  

Expected cost = 212.50 + 1387.50  

Expected cost = $1,600

Hence, Expected Cost under PLAN B = $1600

So, Option D. $1600 is correct

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
