Answer:
P(POSc/Sc)
Step-by-step explanation:
As,
POS= Test has positive results
and
S=Adult has tuberculosis.
The test correctly identifies 74.6% of the time adults with a tuberculosis and correctly identifies those without tuberculosis 76.53% of the time.
In the above statement 76.53% describes the probability of adult who don't have tuberculosis gets the negative results as test is correctly identifying.
So, getting negative results means that not positive results and for this event the notation of complement POSc is used. Also, not having tuberculosis can be denoted as Sc. So,
POSc= Test has negative results
Sc=Adult hasn't tuberculosis
Thus, P(POSc/Sc) depicts the probability of adults not having tuberculosis gets correct results.
Hence, P(POSc/Sc)=76.53%
Hope this helped! the answer is 2^7
Answer:
Cost to buy and run the first car for 5 years=$24000
Cost to buy and run the second car for 5 years=$26000
I think we should buy the first car, because It is cheaper to buy and maintain
Step-by-step explanation:
first car:
Cost $18000 to buy
Cost $100 to maintain each month
5years =5 x 12=60months
Cost to maintain for 60months=100x60=$6000
First car cost to buy and run over the 5 year period=18000+6000=$24000
Second car:
It cost $22400 to buy
Cost $60 to maintain each month
5years=60months
Cost to maintain for 60months is 60 x 60=$3600
Cost to buy and run over the second car for 5years is 22400+3600=$26000
