How many bit strings of length 12 are palindromes and contain 10 as sub string
andre [41]
There are as many palindromic 12-bit binary strings as there are permutations with repetition of 6-bit binary strings, which is equal to 2^6=64.

There are also only two permutations with repetition of 6-bit binary strings, that when each of them is mirrored and the result is "glued" to the right side of the original string, will give a palindromic string without 10 as a substring.
Those strings are 000000 and 111111.

Therefore there are 64-2=62 palindromic 12-bit binary strings with 10 as substring.

The lengths of plate glass parts are measured to the nearest tenth of a millimeter. The lengths are uniformly distributed with v
yarga [219]

Answer:     \text{Mean length}=590.5\ mm\\\\\text{Variance of the lengths}=0.03\ mm

Step-by-step explanation:

The mean and variance of a continuous uniform distribution function with parameters m and n is given by :-

\text{Mean=}\dfrac{m+n}{2}\\\\\text{Variance}=\dfrac{(n-m)^2}{12}

Given : m=590.2\ \ \ n=590.80

\text{Then, Mean=}\dfrac{590.2+590.8}{2}=590.5\ mm\\\\\text{Variance}=\dfrac{(590.8-590.2)^2}{12}=0.03\ mm
