Imagine that I want to make a 4-step random walk. I am fixed to a single dimension - I can take a step to the left or a step to the right. I will decide the direction I will walk by flipping a coin. If the coin lands heads up (H), I will take a step to the right, and if the coin lands tails up (T), I will take a step to the left. I will toss the coin four times in a row and make note of my final location. How many final locations are possible after four coin tosses

26

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
