Suppose that for X = net amount won or lost in a lottery game, the expected value is E(X) = ?$0.50. What is the correct interpretation of this value?
A. The most likely outcome of a single play is a net loss of 50 cents. B. A player will have a net loss of 50 cents every single time he or she plays this lottery game. C. Over a large number of plays the average outcome for plays is a net loss of 50 cents. D. A mistake must have been made because it's impossible for an expected value to be negative

Provide an appropriate response.Suppose that you start a business manufacturing and selling computers, and it costs you $7995 to get started. You determine that each computer will cost $852 to manufacture. Write and explain a linear equation which gives your total cost to manufacture x computers in terms of y1 (in dollars).
A. To find the total cost, multiply the number of computers (x) by the cost per computer (7995 dollars) and subtract the fixed cost (852 dollars). Thus, y1 = 7995x - 852 gives this total cost (in dollars). B. To find the total cost, multiply the number of computers (x) by the cost per computer (7995 dollars) and add the fixed cost (852 dollars). Thus, y1 = 7995x + 852 gives this total cost (in dollars). C. To find the total cost, multiply the number of computers (x) by the cost per computer (852 dollars) and add the fixed cost (7995 dollars). Thus, y1 = 852x + 7995 gives this total cost (in dollars). D. To find the total cost, multiply the number of computers (x) by the cost per computer (852 dollars) and subtract the fixed cost (7995 dollars). Thus, y1 = 852x - 7995 gives this total cost (in dollars).
Solve the equation by multiplying both sides by the LCD.
