Consider two classes, A and B, playing "coin toss" until one of the classes wins n games. Assume that the probability of A, tossing coin "head" is the same for each game and equal to p, and the probability of A tossing coin "tail" is 1-p. (Hence, there are no ties.) Let P(i,j) be the probability of A winning the series if A needs i more coin tosses to win the series and B needs j more coin tosses to win the series. Set up a recurrence relation for P(ij) that can be used by a dynamic programming algorithm. P(ij) = p P(i-1.j-1) + (1-p) P(i-1.j-1) P(ij) (1-p) P(i-1.j) + p P(ij-1) P(ij) p P(i-1.j) + (1-p) P(i.j-1) P(i+1j+1)= p P(i-1.j) + (1-p) P(ij-1) P(i+1j+1) = p P(ij) + (1-p) P(ij)

1. Determine the equation of the line through the given point (a) parallel and (b) perpendicular to the given line Given: Point: ( -1,-4) Line: 4x-2y=3 2. Draw the line 4x-2y=3 and your answer for letter (a) in problem number 1 3. Draw the line 4x-2=3 and your answer for letter (b) in problem number 1 4. a2x-7ay+5a=0 Reduce the given equation to (a) intercept form (b) slope-intercept form A is the last two digit of your ID number, for example your ID number 20201000111, then (a) is 11 hence your equation would be 22x-77y+55=0
The annual snake festival is upon us and all the snakes of the kingdom have gathered to participate in the parade. The chef was tasked with reporting on the parade, so he decided to watch all the snakes first. When he sees the snake first, it will be his head, so he marks the "H". Snakes are long, and when they see the snake finally scurry away, they mark its tail with a "T". In the interim, when the snake is moving around it, or in the time between one snake and the next snake, it marks a '.'. Since the snakes come in a procession and one by one, a valid message would be something like "..H..T...HTH....T.", or "...", or "HT", while "T ...H..H.T", "H..T..H", "H..H..T..T" would be invalid messages (see explanation below). Formally, a snake is represented by an 'H' followed by some (possibly null) '.' and then 'T'. A valid message is one that begins with the (probably zero-length) string '.' and then some (possibly zero) snakes, with some '.'s in between, and finally some (possibly zero)…

5:10 Question 4 of 15 .5G Which of the following describes the entropy change in the given reaction? 2 Cl₂O(g) → 2 Cl₂(g) + 7 O₂(g) Submit A) The entropy change is negative because a larger molecule (Cl₂O₂) is converted into two smaller molecules (Cl₂ and O₂). B) The entropy change is zero because the reactants and products are all gases. C) The entropy change cannot be determined because the temperature is not specified. D) The entropy change is negative because there are more moles of products than reactants. Tap here or pull up for additional resources E) The entropy change is positive because there are more moles of products than reactants.
