Answer:
The probability that a person selected at random has virus and is aged between 21 and 25 is 0.58.
Explanation:
let A be the event that the selected person has a virus.
let B1, B2 and B3 be the events that the selected perosn is M, W and L accordingly.
the probabilities are given by:
P(B1) = 0.3
P(B2) = 0.5
P(B3) = 0.2
P(A|B1) = 0.65
P(A|B2) = 0.82
P(A|B3) = 0.5
probability of having virus and aged between 21 and 25 is given by:
[P(B2)*P(A|B2)]/[P(B1)*P(A|B1) + P(B2)*P(A|B2) + P(B3)*P(A|B3)]
= [(0.5)*(0.82)]/[(0.3)*(0.65) + (0.5)*(0.82) + (0.2)*(0.5)]
= 0.58
Therefore, the probability that a person selected at random has virus and is aged between 21 and 25 is 0.58.
Answer:
These statements are correct:
In a command economy, state-owned enterprises have little incentive to control costs and be efficient.
In a command economy, the absence of competition means that state-owned enterprises do not have incentive to be efficient. This is because In command economies, these companies are most of the time monopolies who have a safer market to sell their products, because consumers lack choice.
Mixed economies were once uncommon throughout much of the world, although they are becoming more popular now.
Most economies now are mixed: in part free market economies, in part command economies. For example, in most developed countries, most sectors are left for private companies to compete, but a few areas are still directly controlled by the government, either fully or partially (for example: the healthcare sector, and education).
Answer:
See below
Explanation:
Given that,
Accounts receivables :
Beginning balance 1 September = $22,400
Services on account = $45,000
Cash collected = $34,400
Written off accounts = $2,000
Allowance for doubtful accounts:
Beginning balance 1 September = $4,400
Adjusted balance for Allowance for doubtful accounts on 30th September
= Beginning balance 1 September - Written off accounts + Bad debt expense
= $4,400 + $2,000 + ($45,000 × 8%)
= $4,400 + $2,000 + $3,600
= $6,000
