Answer:
-15
Step-by-step explanation:
3x+5=BD
4x+20=AE
3x+5 = 4x+20
subtract 3x from 4x = 1x = x
subtract 20 from 5 = -15
-15=x
Answer:
At the end of the 2 year, the book value of the truck is $12,600
Step-by-step explanation:
we know that
<u><em>Double declining balance method</em></u> is a form of an accelerated depreciation method in which the asset value is depreciated at twice the rate it is done in the straight-line method.
Step 1
Determine the straight-line depreciation rate
Divide the total cost by the number of years in the asset's useful life.

Step 2
Then, multiply that number by 2 and that is your Double-Declining Depreciation Rate
-----> is the depreciation for Year 1
Step 3
At the end of the first year, the book value of the truck is

Step 4
For Year 2, we will apply the same formula to the book value of the truck by the end of Year 1

-----> is the depreciation for Year 2
therefore
At the end of the 2 year, the book value of the truck is

Answer:
Upper P95 = 16.21in
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:

Upper P 95
This is the 95th percentile, which is X when Z has a pvalue of 0.95. So X when Z = 1.645.
Then




Upper P95 = 16.21in
the difference between those two bird wingspans is 115.4 inches
