Answer:
And we can find the nnumber of deviations from the mean for each limit given:


So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values
Step-by-step explanation:
Let X the random variable that represent the amount of time it takes him to arrive, and for this case we know the distribution for X is given by:
Where
and
We want to find this probability:
And we can use the z score formula given by:
And we can find the nnumber of deviations from the mean for each limit given:


So we are 3 deviation from the mean and using the empirical rule we know that within 3 deviations from the mean we have 99.7% of the values
Answer:
-19
Step-by-step explanation:
When you subtract from a negative it becomes a bigger number in the negatives. Subtract from a negative is also kind of like adding the 2 numbers then making it negative.
<u>Example:</u>
-2 - 2 = -4
2+2=4 making it negative will give you the answer of -4
-9-10 is like 9+10 which equals 19. Making it negative will give you the answer of -19
