Step-by-step explanation:
Consider the provided information.
For the condition statement or equivalent "If p then q"
The rule for Contrapositive is: Negative both statements and interchange them.
Part (A) If you are taller than 6 ft, then it is unpleasant for you to travel in economy class.
Here p is "you are taller than 6 ft, and q is "it is unpleasant for you to travel in economy class".
It is given that Your contrapositive must not contain explicit references to negation. Assume that the negation of "unpleasant" is "pleasant".
Contrapositive: If it is pleasant for you to travel in economy class then you are not taller than 6 ft then.
Part (B) "If x ≥ 0 and y ≥ 0 then xy ≥ 0" where x, y are real numbers.
Here p is "xy≥ 0, and q is "x ≥ 0 and y ≥ 0"
The negative of xy≥ 0 is xy<0, x ≥ 0 is x<0 and y ≥ 0 is y<0.
Remember negative means opposite.
Contrapositive: If xy < 0 then x<0 and y<0.
900 ÷ 72 = 12.5 minutes
Thus the correct answer is option A .
The answer is b.) sorry if I’m wrong but I did the work and got b.)
Considering the amount they raised and the amount they spent, it is found that the art club had $358 after the show.
