Is this compound statement true or false?

Is the compound statement true or false?





If 15+8=23 then 57/5 =11Is this compound statement true or false?
The statement is false.





An ';implication'; is a statement of the form ';If P then Q.'; An implication is false exactly when P is true and Q is false. So if T is some true statement and F is some false statement then:


(1) ';If T then T'; is true.


(2) ';If T then F'; is false.


(3) ';If F then T'; is true.


(4) ';If F then F'; is true.





For example:


(1) ';If 15+8=23 then 57/5 = 11 2/5.'; is TRUE


(2) ';If 15+8=23 then 57/5 =11.'; is FALSE


(3) ';If 15+8=24 then 57/5 =11 2/5.'; is TRUE


(4) ';If 15+8=24 then 57/5 =11.'; is TRUE





Your statement is of type 2, and is false.Is this compound statement true or false?
CAN BE TRUE AND CAN BE FALSE ITS ALL IN UR MIND
false because 5x11 is 55 not 57.
false because 5x11 is 55 not 57.
true because their is no telling what each # is worth to u
false
