Mount mckinley in alaska is 20,320 feet above sea level. Mauna kea in hawaii is 13,796 feet above sea level. How many more feet
1 answer:
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- Mount Mckinley is 20,320 feet above sea level.
- Mauna kea is 13,796 feet above sea level.
2. Then, you only need to substract both quantities to solve the exercise, as following:
Therefore, as you can see, the answer is: 6,524 feet.

Answer:
And we can find this probability with the following difference:
We can use the following commands on the ti 84
2nd>VARS>DISTR
And then we look for normalcdf and we input this:
normalcdf(0.7,1.4,0,1)
The other possible code would be:
normalcdf(-1000,1,4,0,1)-normalcdf(-1000,0.7,0,1)
And we got:
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
For this case we want to find this probability:
And we can find this probability with the following difference:
We can use the following commands on the ti 84
2nd>VARS>DISTR
And then we look for normalcdf and we input this:
normalcdf(0.7,1.4,0,1)
The other possible code would be:
normalcdf(-1000,1,4,0,1)-normalcdf(-1000,0.7,0,1)
And we got:
