Binary Heap: Extract Max seems wrong: O(n log(n))

[murraycu]

bigoref.com lists the average time complexity of Extract Max for a Binary Heap as O(n log(n)), but it should apparently be O(log(n), as it is on bigocheatsheet.com and in wikipedia:

The other time complexities for binary heap seem wrong too. And for Binomial Heap too, I think,

Incidentally, this seems to be correct on bigocheatsheet.com.
