First step when finding the mean is to add all the values together
7 + -9 + 6 + -10 + -13 + -5
To make this easier, first add all the positive numbers 7 + 6 = 13
Then add (basically take away) the minus values one by one
13 - 9 = 4
4 - 10 = -6
-6 - 13 = -19
-19 - 5 = -24
Next step is to divide this total by the number of values there were
In this case, there were 6 values
-24 / 6 = -4
D. -4
The book value of the equipment is $14000
Given,
equipment cost = $20,000
depreciation amounts = $6,000
book value of the equipment = equipment cost - depreciation cost
= 20000 - 6000
= $14000
<h3>What Are Depreciation Expenses?</h3>
Depreciation expense, on the other hand, is the amortized portion of the cost of the business's fixed assets during a certain period. Depreciation expense is recognized in the income statement as a non-cash expense that reduces the net income or profit of the business. For accounting purposes, depreciation expense is debited and accumulated depreciation is credited.
Depreciation expenses are treated as non-cash expenses because periodic monthly amortization is not involved in cash transactions.
