If all the sectors are the same size, the probability of landing at 5 is 1/6.
This is because it is going to land in one sector out of 6 possible sectors.
Answer: Option A -439
(s o t)(x)=s(t(x))
(s o t)(-7)=s(t(-7))
x=-7→t(-7)=3(-7)→t(-7)=-21
(s o t)(-7)=s(t(-7))=s(-21)
x=-21→s(-21)=2-(-21)^2=2-441→s(-21)=-439
(s o t)(-7)=s(t(-7))=s(-21)=-439
Answer: Option A -439
Answer: 
Step-by-step explanation:
Given: Fraction of 7th graders got A = 
Fraction of 7th graders got B = 
The fraction of the students got an A or B = Fraction of 7th graders got + Fraction of 7th graders got B

Hence, the required fraction: 
As x increasing y decreases.
As x decreases, y increases.
