Consider u = {x|x is a positive integer greater than 1}. which is an empty set? {x|x ∈ u and 1/2x is prime} {x|x ∈ u and 2x is prime} {x|x ∈ u and 1/2x can be written as a fraction} {x|x ∈ u and 2x can be written as a fraction}

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

the answers are in the images, i received 100% on this assignment. hope this !
