Suppose we roll two fair four-sided dice. let x denote the sum of the two roll outcomes. for example, if the first roll yields "3" and the second roll yields "1," then x = 3 + 1 = 4. the probability distribution for x is given: value of x 2 3 4 5 6 7 8 probability 1/16 2/16 3/16 4/16 3/16 2/16 1/16 p(x < 5) has value:

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
