A bit string of length refers to a sequence of bits, each of which can be either 0 or 1, that is a fixed length. The total number of possible bit strings of length n is 2^n.
To start, let's define what the function w() represents. The function w(x) returns the Hamming weight of bit string x, which is the number of positions in the string where the bit is 1.
Now, we need to prove that w(x y) = w(x) w(y)− 2m, where x and y are bit strings of length n and m is the number of positions where both x and y have 1s.
First, let's consider the case where x and y have no 1s in common. In this case, m=0 and w(x y) will be equal to the Hamming weight of the concatenated string x y, which is the sum of the Hamming weights of x and y.
This is because there are no positions in which both x and y have 1s, so the number of 1s in x y will be equal to the number of 1s in x plus the number of 1s in y.
Now, let's consider the case where x and y have some 1s in common. In this case, we need to subtract the number of overlapping 1s from the sum of the Hamming weights of x and y, since these overlapping 1s will be double-counted in the concatenated string x y. The number of overlapping 1s is equal to 2m, since each position where both x and y have a 1 will be counted twice in the concatenated string.
Therefore, we can express w(x y) as w(x) + w(y) - 2m, which is equivalent to w(x) w(y) - 2m. This completes the proof.

Create a round object to hang in your window that will touch the midpoints of all four edges of your window
The round object that can touch the midpoints of all four edges of a window is illustrated by a circle with dimensions.(x-h)² + (y-k)² = r².
What is a midpoint?It should be noted that a midpoint is a point that is lying between two points and is in the middle of the line joining the two points.
Based on the information given, the center is (h,k) and tthe radius = r.
Top of the circle = (h,r+k) = midpoint of the window's top
The circle's bottom = (h,k-r)=midpoint of the window bottom
The left edge of the circle = (h-r, k)=midpoint of the window's left side
The right edge of the circle = (h+r, k)= midpoint of the window's right side

Answer:

Explanation:
In a typical office, biometric authentication might be used to control access to employees and registered visitors only. We know the system will have some false negatives, some employees falsely denied access, so we need a human override, someone who can examine the employee and allow access in spite of the failed authentication. Thus, we need a human guard at the door to handle problems as well as the authentication device; without biometrics, we would have had just the guard. Consequently, we have the same number of personnel with or without biometrics, plus we have the added cost to acquire and maintain the biometrics system. Explain the security advantage in this situation that justifies the extra expense.
The security advantage in this situation that justifies the extra expense is that these Biometric devices is one that separates the handling of issues regarding biometric information from the system operating system.
