Answer: P(B)= 15 P(A^c)
Step-by-step explanation:
Multiply the first one then the second one multiply and then do to the 2nd power
I do not speak Spanish sorry :(
X= -10/17 .................................................
It is 4 as you can see every y in the table is 4 time bigger than x.
Answer:


So the best answer for this case would be:

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 costs of unleaded gasoline of a population, and for this case we know the distribution for X is given by:
Where
and
We select a sample size of n =16. Since the distribution for X is normal then we know that the distribution for the sample mean
is given by:


So the best answer for this case would be:
