Answer:
P =44 cm
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 = s^2
Taking the square root of each side
sqrt(121) = sqrt(s^2)
11 = s
We want to find the perimeter of a square
P = 4s where s is the side length
P = 4(11)
P =44 cm
Answer:
160, 160, 200, 200
Step-by-step explanation:
All you have to do is double the numbers.
Answer:
25 numbers
Step-by-step explanation:
we have five different bases to choose from
(1,2,3,4,5)
The expected length of code for one encoded symbol is
where is the probability of picking the letter , and is the length of code needed to encode . is given to us, and we have
so that we expect a contribution of
bits to the code per encoded letter. For a string of length , we would then expect .
By definition of variance, we have
For a string consisting of one letter, we have
so that the variance for the length such a string is
"squared" bits per encoded letter. For a string of length , we would get .
