Ответ:
And we can find this probability with thi difference:
And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.
So then we expect about 72.5% of the current shipment times between 1 and 5 days
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 current shipment time of a population, and for this case we know the distribution for X is given by:
Where
and ![\sigma=1.5](/tpl/images/0560/3446/fc192.png)
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 with thi difference:
And in order to find these probabilities we can use tables for the normal standard distribution, excel or a calculator.
So then we expect about 72.5% of the current shipment times between 1 and 5 days
Ответ:
1.25π
Step-by-step explanation:
Hello There!
The area of a sector can be found using this formula
where 0 = angle and r = radius
so given the measures r = 3 and 0 = 50 all we have to do is plug in the values into the formula
so...
so the area of the sector = 1.25π
Note: it says to leave your answer in terms of pi so we do not have to apply pi
