Question

Is this correct?

Answer 1

I don't think it's correct. Let's wait for AravindG

Answer 2

A disjunction is a compound statement formed by joining two statements with the connector OR. I dont see usage of OR in your statement.

Answer 3

Oh wait...I just noticed.

Answer 4

I think you should make the disjunction relative base on your condition and your conclusion is :
1/ I have to study from 8 to 4
2/ I can hand out at the time before 8 or after 4
then your interval is correct,

Answer 5

Ok so you have formed the example using OR But you have mentioned an interval not belonging to it. So are you referring to the case where you dont study?

Answer 6

however, the interval is just (0,8) or (16,24) not infinitive

Answer 7

^^

Answer 8

because time start at 0 and end at 24

Answer 9

I was about to say that too. You will also study from 8 to 4 in the previous day. So that is cannot be included.

Answer 10

The provided answers above mainly agree with all my thoughts regarding this question. The interval firstly would be infinitive (as time starts from 0-24).

Answer 11

Why are you still going for infinity? We are referring to time here in a day. Its maximum value is 24 hours.

Answer 12

I made a small change in the ending:

An example of disjunction that is used in the real world could be when I start and end my schoolwork. I start studying at 8 am and end at 4 pm, this means that I can am not studying before 8 am or after 4 pm. This means that I have started my schoolwork at 8am or after (x>8) and I have ended my schoolwork at or before 4pm (x≤). The interval notation of the time when I do not study would be (0, 8) U (16,24).

Answer 13

Sorry @AravindG. My mistake I was meant to say that it *wouldn't be infinite as time in a day is valued as 24 hours in total...

Answer 14

Yeah np @Silver-Fox Everyone makes mistakes :)

Answer 15

@adrianajones Did that help?

Answer 16

The time you dont study is either (0,8) OR (4,24). Yes that is a disjunction.

Answer 17

agree!! XD
