You start driving north for 27 miles, turn right, and drive east for another 36 miles. At the end of driving, what is your strai
1 answer:
Answer:
Step-by-step explanation:
If you drive straight north then turn and drive straight east, you have driven 2 sides of a right triangle. The straight line distance from where you are to where you started from is the hypotenuse of the right triangle. Use Pythagorean's Theorem to solve:
and
and
That means that length of the hypotenuse is 45.
45 miles is the distance.

Step-by-step explanation:
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".
The population proportion have the following distribution
And we can solve the problem using the z score on this case given by:
We are interested on this probability:
And we can use the z score formula, and we got this:
And we can find this probability like this:
