Answer:
Realization :
since there are 3-variable. Therefore 2ⁿ = 2³ = 8
From the attached solution, f(x,y,z) = y' + xz'
also' see the circuit diagrams of my realizations of AND-OR and NAND-NAND
Step-by-step explanation:
See attached picture for minimal 2-level AND-OR and NAND-NAND of the logic function.
f(x,y,z) = y' + xz' was designed from the function f(x,y,z) = Σm(0,1,4,5,6)
Then, minimal 2-level AND-OR was designed and after was NAND-NAND designed as well.
Answer:
In order to find the variance we need to calculate first the second moment given by:
And the variance is given by:
And the deviation would be:
Step-by-step explanation:
Previous concepts
The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.
The variance of a random variable X represent the spread of the possible values of the variable. The variance of X is written as Var(X).
Solution to the problem
For this case we have the following distribution given:
X 3 4 5 6
P(X) 0.07 0.4 0.25 0.28
We can calculate the mean with the following formula:
In order to find the variance we need to calculate first the second moment given by:
And the variance is given by:
And the deviation would be:
