I'll help you with some of your questions:
Everyone, in each fishing session, caught at least 10 fish (each in each session).
Let Fxz- x is in z fishing session.
Gxy-x caught y fish.
Not sure if I got this right, though.
Determine the truth sets for the statement forms i: A'(x)^C(x); ii: B(x)-->A(x)
where A(x): x^2-9<0, B(x):3x+3(greater than/equal to)0, C(x):|2x-5|>4
i) |2x-5|>4 means 2x-5>4 or 2x-5<-4 after rearranging this and combine it with the negation of A(x) which is x^2-9>=0 which means either x>=3 or x<=-3 you will get whatever answer it would be. for ii use material conditional where B(x)->A(x) is the same as: ~(B(x)&~A(x)).
