3.44 each rear tire on an experimental airplane issupposed to be filled with a pressure of 40 pound per squareinch(psi).let x denote the actual air pressure for the right tireand y denote the actual air pressure for the left tire. suppose that xand y are random varibles with the jointdensity
f(x, y)= k(x^2+y^2, 30< -x< 50;
30< -y< 50
0, elsewhere
a.) find k
b.) find p(30< -x< -40 and 40< -y< 50)
c.) find the probability that both tires areunderfilled.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
