Answer:
a) P(identified as containing explosives)=P(actually contains explosives and identified as containing explosives)+P(actually not contains explosives and identified as containing explosives)
=(10/(4*106))*0.95+(1-10/(4*106))*0.005 =0.005002363
hence probability that it actually contains explosives given identified as containing explosives)
=(10/(4*106))*0.95/0.005002363=0.000475
b)
let probability of correctly identifying a bag without explosives be a
hence a =0.99999763 ~ 99.999763%
c)
No as even if that becomes 1 ; proportion of true explosives will always be less than half of total explosives detected,
The answer to the question is b
Answer:
The quick ratio is 4.75:1.
Step-by-step explanation:
From the given information it is clear that:
Cash = $340,000
Inventory = $280,000
Accounts receivable = $40,000
Accounts payable = $65000
Other current liabilities = $15000
Formula for quick ratio:
Substitute Cash = 340000, Current receivables=40000, Current Liabilities= (65000+15000).
Therefore the quick ratio is 4.75:1.
When you regroup you are basically breaking down the problem.
You would do 60 + 40=?
Then you would do 4 + 3= ?
Your answer would come out to 107
