In question 11 b . Do we need to find the lower bounds for other angles and then find angle o or we need to find the angles and then the lower bound for that angle?

Here you go bro can you please help me with question 14(b) and 15(b)

14b is 11/20
Since ( 1/4 * 2/5) +(3/4*3/5) shows the probabilty of winning one Only

360-46.5-162.5=151

is this the ans..

U need the lower bound for the others,ithink

 

[Bilal Kamal]

you need to find the upper bound for angle AOC and AOB .add them and subtract the value obtained after addition from 360

no the upper bound for others to get the lowest number for boc....

 

[Dream.Eater]

360-46.5-162.5=151

is this the ans..

Yeah,i got the same

 

[Dream.Eater]

Oops sorry.made a mistake in wording there

My gifs have made you blind. Haha

 

[Mahnoorfatima]

360-46.5-162.5=151

is this the ans..

Yep. So we have to find the lower bounds for the others first.

Q 21 b and c as well please?

 

[Mahnoorfatima]

How are you supposed to do these questions? Don't just tell me the answers - tell how did you solve this. I know nothing on these questions

I guess you gotta rote learn the graphs, there is no specific method for that. Well I've done so, from the notes my teacher gave me.

 

[Awesome12]

My gifs have made you blind. Haha

 

[Mahnoorfatima]

Well can you give me the lists of all the possible graphs?

Lol I would. But I don't know how to share a picture through my iPad as my laptop is out of order, google it. Like the list I have is:
1. Quadratic curve
2. Cubic curve
3. Reciprocal graphs,
4.exponential graph
That's all. I've got examples as well bit unfortunately I don't know how to post it.

 

[FLRNAB]

Yeah right. That's impossible.

Be warned:

if u have D4, see its first chapter.
