(the sum of annual average book values) ÷ asset’s life
(beg book value +the end book value) ÷ 2.
Explanation:
Depreciation is simply when an asset begin to wear and tear and thereby its value is reduced.Straight line depreciation is calculated when the difference between the cost of an asset and the expected salvage value is divided by the number of years it is projected to be used.
Using this method, the annual average investment can be calculated as:
• beg book value +the salvage value) / 2.
• (the sum of annual average book values) ÷ asset’s life
Option b. A and B are conditionally independent given C2.
Explanation:
The conditional probability of an event is the probability that a given event will occur given that another event, say A has already occurred.
In a case where events A and B are independent (in this case, where the probability of A has no effect on the probability of B occurring), the conditional probability of an event B given that A has taken place is simply the probability of the event A.
If the two events are not independent, then the probability of an event occurs as an intersection of set A and B.
