I know u gonna use calculator girl.
Answer:
the answer is option c
c)60
Step-by-step explanation:
From the given statement 2 × 3 mixed factorial design where 2 is a factor which is within the subject and
3 is the subject between the subject
then observation per cell where participants will need is 3* 20 = 60 because 3 is the factor between the subject.

Answer:
y = In | cos(2x + c ) | + c
Step-by-step explanation:
y" + (y')^2 + 4 = 0
substituting u = y'
u' + u^2 + 4 = 0
hence : u' = - (u^2 + 4 )
= 1 ------- (1)
integrating both sides of the equation 1
x + c = hence u = -2 tan(2x + c )
remember u = y'
y' = -2 tan(2x + c) ------ (2)
integrating both sides of the equation 2
y = ∫
therefore Y = In | cosu | + c
y = In | cos(2x + c ) | + c
