A manufacturer has been using two different manufacturing processes to make computer memory chips. Let X denote the time failure of chips made by process A and Y denote the time failure of chips made by process B. Consider the two random variables (X, Y) jointly. It is known that the joint PDF of (X, Y) is:

fₓ,ᵧ (x, y) = { ab e⁻⁽ᵃˣ⁺ᵇʸ⁾, x > 0, y > 0
{ 0 otherwise
where a = 10⁻⁴ and b = 1.2 (10⁻⁴).

Find P(X

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
