Astatistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 50.0 and 60.0 minutes. find the probability that a given class period runs between 50.25 and 51.5 minutes.

0.125

Step-by-step explanation:

The probability density function for a uniformly distributed function in interval [a,b] is given by :-

Given : A statistics professor plans classes so carefully that the lengths of her classes are uniformly distributed between 50.0 and 60.0 minutes.

Let x denotes the lengths of classes.

Then, Density function =

Now, the probability that a given class period runs between 50.25 and 51.5 minutes is given by :_

Hence, the probability that a given class period runs between 50.25 and 51.5 minutes = 0.125

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
