Answer:
5
Step-by-step explanation:
Answer:
5.1
Step-by-step explanation:
Since there is no diagram provided here, we assume that c is the length of the hypotenuse, so we have ...
c² = a² +b² . . . . . . Pythagorean theorem
c² = 2.7² +4.3² = 25.78
c = √25.78 ≈ 5.0774
c ≈ 5.1
Answer:

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:

7 is the answer 4 and lower you round down 5 and up is up
