In airline applications, failure of a component can result in catastrophe. as a result, many airline components utilize something called triple modular redundancy. this means that a critical component has two backup components that may be utilized should the initial component fail. suppose a certain critical airline component has a probability of failure of 0.0066 and the system that utilizes the component is part of a triple modular redundancy. (a) assuming each component's failure/success is independent of the others, what is the probability all three components fail, resulting in disaster for the flight? (b) what is the probability at least one of the components does not fail?

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =

X/y + 4y/x divided by x/y - 2y/x explain as in depth as you can how you simplfied the fractions. i don't know where to start on this : /
