Richiez: that should be Denniece1

bitex2: Let sinx be = y
substitute for y
2y^2+3y+1=0
factorize
(2y-1)(y-1)=0
y=1/2 or 1
hence sinx=1/2 or 1
x=sin^-1(1/2)=30 or 150
OR
X=Sin^-1(1)=90
x=30,90,150 degrees
range of x is
30_<x_<150
pls i am a newcomer here i dont knw the particular email to message my solution to.PARDON

.
The set of people we are concerned with are the Lunchers => U = 50
D for Dodo R for Rice and B for Beans

D & R only = 6
B only = 22
B, R & D = 3
B & R only = 5
B & D only = 7 - 3 = 4 (i.e minus those that ate the Holy Trinity )
D only = R only = x

50 = x + 6 + x + 4 + 5 + 22 + 3
x = 5

(1) Those who Rice anyhow = 5 + 6 + 3 + 5 = 19 students (As you must have noticed, this answer is diff from my initial post Too much AKPU dey worry eye, This one is correct though, as far as I can see )
(2) Dodo People = 5 + 6 + 3 + 4 = 18 students.

Kendzyma: bro its 30 and 90....

smurfy:

He is right.

busuyem:

Sorry, I think ur solution is wrong because u made use of 50 as the universal set when universal set is 2000. 50 is just the number of those that do not partake in the three food (Beans, Rice and Dodo). Check ur workings again.

factorial1: ...ehm *clears throat* like seriously, I just dey refreash page...finding it difficult to get my brain @ease...lowkey tinx, hope my ans. correct sha....?

aysuccess99:
bro factorial, lowkey tinz ke.......? if i hear....? u dat i saw carying pen and one big jotter solving like a maths guru,which u are, nd using three big calculators:casio, porpo and one big scientific calc...i hail o my oga.

Richiez: 2Sin²x - 3Sinx + 1 = 0

find x

don't panic time just started counting

Alpha Maximus: Next question loading..

aysuccess99:
i always fear this guy qstn......anyway let it load fast o...what abt d soln of d first one nd scoreboard

Kendzyma: Master jaryeh!!!!!!!!

jaryeh:

Oga mi

Kendzyma: Chai...only 1 question since

factorial1: following though...no calculator, no pen(*coughs*) to solve, nothing nothing! Me Ah no du again jawe...
