In the city where aiko lives, there are 44 buses that go from point aa to point bb, 33 buses that go from point bb to point cc, and 55 buses that go from point cc to point dd. how many different ways can aiko use the buses to travel from aa to bb to cc to dd? there are __[blank]__ different ways that aiko can use the buses to get from aa to bb to cc to dd. enter your

  60

Step-by-step explanation:

For each of the 4 buses from A to B, Aiko can take 3 possible routes to C, for a total of 4×3 = 12 ways to get from A to C.

Then, for each of those, Aiko can take any of 5 buses to D, for a total of 12×5 = 60 different ways Aiko can use buses to get from A to D.

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
