You toss a fair coin 9 times, and record all the outcomes. A sequence is any consecutive runs of coins that have the same outcome. For instance, the outcomes : HHHTTH have 3 sequences, of lengths 3, 2, and 1 respectively. On expectation, how many sequences do you observe? Pick one of the choicesa. 3b. 4.5c. 5d. 6

b or 2, just plug these equations into your graphing calculator then check the graph to see the image. if it matches up then that's your answer!

b

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
