Divide the given terms:

4/1 = 4

16/4 = 4

64/16 = 4

R = 4

The next term is the previous term multiplied by 4.

64 x 4 = 256

256 x 4 = 1024

1024 x 4 = 4096

The next three terms are: 256, 1024, 4096

The probability of multiple events happening is found by multiplying the probabilities of each event together.

P_{d+even\ number}=P_{d}*P_{even}\\\\P_{d}=\frac{number\ of\ events}{total\ number\ of\ events}=\frac{(d)}{a,\ b,\ c,\ d,\ e)}=\frac{1}{5}\\\\P_{even}=\frac{number\ of\ events}{total\ number\ of\ events}=\frac{(2,\ 4,\ 6)}{(1,\ 2,\ 3,\ 4,\ 5,\ 6)}=\frac{3}{6}=\frac{1}{2}\\\\\frac{1}{5}*\frac{1}{2}=\boxed{\frac{1}{10}}

So yes, 1/10 is the answer :)

Select the best answer to complete the sentence. A Rigid Motion or Isometry ______________________.
Dmitry_Shevchenko [17]

Answer: A. preserves length, angle measures and distance between points

Rigid motions or isometries are any of the three transformations below

  • translation (aka shifting)
  • rotation
  • reflection

Any of those three transformations will keep the figure the same size and shape. That means distances between any two points are kept the same, and angle measures are kept the same as well. Everything is kept the same. The only difference is that the figure is in a different location, is rotated somehow, or it is reflected some way. You can use a series of transformations to undo everything to get the original figure back.

If you wanted to change the size of the figure, then you would apply dilation, which isn't an isometry.
