so i have these for homework, i dont udnerstand them due to me having a adhd comprehension problem, is there anyone who can walk me through them?

If you sort the elements in D alphabetically, you end up with

D = {a, b, c, d} = E

so right away we have

1. D ⊆ E is true

D is a subset of E because they are the same set, and any set is a subset of itself

2. D ⊂ E is false

Although D is a subset of E, D is not a proper subset of E because they contain the same elements. This would be true if E had any other elements.

3. E ⊆ D is true

4. E ⊂ D is false

5. D = E is true

We've already established at the start.

6. D ≠ E is false

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

the answer is 1/4
