The Two sets A and B are said to be disjoint sets if A n B=_____
asambeis [7]

The Two sets, A and B, are said to be disjoint sets if A n B=ϕ

<h3>What does it mean for two sets to be disjoint?</h3>
  • Disjoint sets are a pair of sets that do not share any elements. For instance, sets A=2,3 and B=4,5 are not connected sets.
  • When two sets don't share elements, they are considered disjoint sets. In other words, the null set will result if we find the intersection of two sets. The process is straightforward; two sets are given in this procedure.
  • When using a disjoint set union, it is possible to add new sets, combine existing sets, and check whether two sets of elements are the same in almost real-time.

By what number must you multiply a quantity in order to increase it by 25% in a single step?
Brrunno [24]

Answer:

5/4

Step-by-step explanation:

Lets suppose a quantity A that has a value of x

A = x

25% of A is = x/4

now adding this 25% to get 25% increase in the original value

A' = x+ x/4

    A' = 5x/4

    A' = 5*A/4

This means that , in order to increase the value by 25%  in a single step we must multiply the the original value by 5/4.
