It is D. There are 12 months in a year and she needs to save atleast 9,000.
600x12=7,200
350x24=8,400
225x36=8,100
200x48=9,600
Answer:
B. $129 million
Explanation:
bad debt expense for the year = balance in allowance at the end + write off - balance in allowance at the beggining
= $319 million + $137 million - $327 million
= $129 million
Therefore, Oracle Corporation report as bad debt expense for the year is $129 million.
Answer:
And we can find this probability using the normal standard distribution table or excel and we got:

Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the expected return, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution table or excel and we got:
