Answer:
attempts are required to find a matching pair if the digital fingerprint is 64 bits long.
attempts are required to find a matching pair if the digital fingerprint is 128 bits long.
Step-by-step explanation:
Each bit has two options. So
How many attempts are required to find a matching pair if the digital fingerprint is 64 bits long?
So for each of the 64 bits, we have the following number of options.
2 - 2 - 2 - 2 -... - 2
So, in all, there are

options.
So,
attempts are required to find a matching pair if the digital fingerprint is 64 bits long.
128 bits long?
Using the same logic as the first question.

So,
attempts are required to find a matching pair if the digital fingerprint is 128 bits long.
Answer:
9) It will be congruent to the original image. Or stay the same.

Step-by-step explanation:
The answer to this question is C. 0.35.
7 divided by 20 = 0.35
<span>140% becomes 140/100. Since the GCF of these terms in the numerator and denominator is 20, divide each term by that value to get 7/5.</span>
