Acoin will be tossed twice, and each toss will be recorded as heads (h) or tails (1). give the sample space describing all possible outcomes. then give all of the outcomes for the event that the second toss is tails. use the format ht to mean that the first toss is heads and the second is tails. if there is more than one element in the set, separate them with commas. 0.0, sample space: {} event that the second toss is tails: {}

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
