Answer:
The number of palindromes is
when n is even and
when n is odd
Step-by-step explanation:
From the question we are told that
The length of the string is ![n](https://tex.z-dn.net/?f=n)
Generally palindrome is evaluated by considering the first part of a string
When the the length of the string is an even number then
it means that the first part of the string is ![\frac{n}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B2%7D)
Hence the number of bit strings of length n that are palindromes is evaluated as
![p(n_{even }) = 2^{\frac{n}{2} }](https://tex.z-dn.net/?f=p%28n_%7Beven%20%7D%29%20%3D%20%202%5E%7B%5Cfrac%7Bn%7D%7B2%7D%20%7D)
But When the the length of the string is an odd number then
it means that the first part of the string is ![\frac{n-1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bn-1%7D%7B2%7D)
Hence the number of bit strings of length n that are palindromes is evaluated as
![p(n_{odd }) =2^{\frac{n -1}{2} +1 } = 2^{\frac{n +1}{2} }](https://tex.z-dn.net/?f=p%28n_%7Bodd%20%7D%29%20%3D2%5E%7B%5Cfrac%7Bn%20-1%7D%7B2%7D%20%2B1%20%7D%20%3D%202%5E%7B%5Cfrac%7Bn%20%2B1%7D%7B2%7D%20%20%7D)
Generally each bit could be either 0 or 1
Hence the number of palindromes is
when n is even and
when n is odd
Answer:
180°
Step-by-step explanation:
Since a sprinkler rotates 90°, pauses,and then rotates another 90°
So, here total degrees be like
= 90° + 90°
= 180°
hence, The number of degrees did it rotate altogether should be considered as the 180 degrees.
I do not see any answer choices....but I do know that the more allowances (dependents) u claim, the less they take out each pay period...but the more u have to pay at the end of the year when taxes are due.
