Answer:
And we can find this probability using the complement rule and the normal standard table or excel:
The firgure attached illustrate the problem
Step-by-step 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 retirement savings of a population, 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 complement rule and the normal standard table or excel:

Answer:
2244.9
Step-by-step explanation:
Anually compound interest formula
PV(1+i)^t
1800(1+.0375)^6
1800*1.0375^6
2244.921387 which rounds to
2244.9
Answer:I think the answer is x=25 sorry if im wrong ツ.
Step-by-step explanation:
Hope this helps you out ツ
Answer:
first we multiply 2357 x 8870
which resulted in 20906590
then we multiply the resultant with 7809 then the final answer is
163,259,561,310
