Answer:
And we can find this probability using the normal standard table or excel:
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 amount of ml 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 normal standard table or excel:
Answer:
The first one 10 units would be the perimenter of the tenth figure.
Answer:
The answer is (1,2) (4,4) (3,7)
Step-by-step explanation:
Answer:
the perimeter is of 148 m
Step-by-step explanation:
the perimeter is the sum of all sides so an square has all sides equal so we have

and the area is

so we find x

and now the perimeter
