Answer: 0.0250
Step-by-step explanation:
Given : A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 50.0 and 60.0 minutes.
We know that the uniform distribution is also known as rectangular distribution.
Density function for uniform distribution :
Now, the probability that a given class period runs between 51.25 and 51.5 minutes :-
Hence, the probability that a given class period runs between 51.25 and 51.5 minutes = 0.0250
The square root of 81 is 9, the square root of 100 is 10. 89 is between 81 and 100, therefore the square root of 89 must be between 9 and 10.
