so everytime, so gotta break it like this? or it depends?

it depends on question
if u nedd to hav break out break if not than dont
in the recnt papers there this usually no nnedd to put it
scale is good=no need for zig zag line!

 

[ahmadumar]

right, so when drawing cumulative freq graph, do we have to pass the line through origin? i never get it?

what is the zig zag means frm the origin??

like this one?

so yeah, draw it as it is in the link u showed me. thats right,
that zig zag at start shows that the numbers before 20 are useless and we dont need them so to save space we dont write the 5 and 10 we just put a zig zag line like that and start from where we need

[dubi2pro]

for this formula of compuund interest,,

A = P + (1 + r/100 ) ^ n

how to make (r) and the subject of formula?

for this formula of compuund interest,,

A = P + (1 + r/100 ) ^ n

how to make (r) and the subject of formula?

get what u r trying to ask here :3

 

[dubi2pro]

i didnt

get what u r trying to ask here :3

the formula for compund interest..

making r the subject of formula!

 

[ahmadumar]

the formula for compund interest..

making r the subject of formula!

move P on the left side. so it becomes A-P= (1+r/100)^n
Now, take under root of n on both sides. then move 100 to left side. and then move 1 to left side done :3 lol
did u get it? :3

nopes!

also what about if wana make n the subject of formula?

 

[dubi2pro]

waiiitt i got it

 

[dubi2pro]

just check if im right, square root of n a-p/100 = r
