The probability that mary will win a game is 0.05, so the probability that she will not win is 0.95. if mary wins, she will be given $80; if she loses, she must pay $4. if x = amount of money mary wins (or loses), what is the expected value of x? (round your answer to the nearest cent.)

Draw out the fraction then show how you would subtract 5 1/4

Demonstrate the proof of your new polynomial identity through an algebraic proof and a numerical proof in an engaging way! make it so the whole world wants to purchase your polynomial identity and can't imagine living without it! you must: label and display your new polynomial identity prove that it is true through an algebraic proof, identifying each step demonstrate that your polynomial identity works on numerical relationships create your own using the columns below. see what happens when different binomials or trinomials are combined. square one factor from column a and add it to one factor from column b to develop your own identity. column a column b (x − y) (x2 + 2xy + y2) (x + y) (x2 − 2xy + y2) (y + x) (ax + b) (y − x) (cy + d)
