"We keep tossing a fair coin n = 10^6 million times, write down the outcomes: it gives a Heads-and-Tails-sequence of length n. W
anyanavicka [17]

Answer:

Check the explanation

Step-by-step explanation:

Let X_{i} be the indicator random variable that takes the value 1 if the ith coin is the first coin in a sequence of 19 consecutive heads.

For any sequence of length 19, the starting coin can be from toss i ,

such that i is between 1 and n - 19+1

Thus the number of such sequences is

Triangle QRS has vertices Q(-4,2),R(3,0), and S(4,3).
Dafna1 [17]

The coordinates of the vertices of \triangle Q'R'S' are Q'(x,y) = (0, -4), R'(x,y) = (7,-6) and S'(x,y) = (8, -3), respectively.

Vectorially speaking, a point is translated to another location on Cartesian plane by means of this expression:

A'(x,y) = A(x,y) + T(x,y) (1)

Where:

  • A(x,y) - Original point.
  • A'(x,y) - Translated point.
  • T(x,y) - Translation vector.

If we know that Q(x,y) = (-4,2), R(x,y) = (3,0), S(x,y) = (4, 3) and R'(x,y) = (7, -6)T(x,y) = (4, -6), then the coordinates of the vertices of the triangle Q'R'S' are:

Q'(x,y) = Q(x,y) + T(x,y)

Q'(x,y) = (-4,2) + (4,-6)

Q'(x,y) = (0, -4)

R'(x,y) = R(x,y) + T(x,y)

R'(x,y) = (3,0) +(4,-6)

R'(x,y) = (7,-6)

S'(x,y) = S(x,y) + T(x,y)

S'(x,y) = (4, 3) + (4, -6)

S'(x,y) = (8, -3)

The coordinates of the vertices of \triangle Q'R'S' are Q'(x,y) = (0, -4), R'(x,y) = (7,-6) and S'(x,y) = (8, -3), respectively.
