Answer:
A polynomial with complex coefficients of degree n has n complex roots, counted with multiplicity.
Step-by-step explanation:
We are given a polynomial p(x) in the question with degree n.
The degree n means the n is the highest power of variable in the given polynomial.
The equation:
Fundamental theorem of Algebra
- The Fundamental theorem of Algebra states that a a polynomial of degree n will have n roots of the equation.
This can further be explained as:
- A polynomial with complex coefficients of degree n has n complex roots, counted with multiplicity.
Answer:
E(x)=0.15
V(x)=0.3075
S(x)=0.5545
Step-by-step explanation:
The mean of a discrete variable is calculated as:
where are the values that the variable can take and
are their respective probabilities.
So, if we call x the number of defective transistors in cartons, we can calculate the mean E(x) as:
Because there are 0 defective transistor with a probability of 0.92, 1 defective transistor with a probability of 0.03, 2 defective transistors with a probability of 0.03 and 3 defective transistors with a probability of 0.01.
At the same way, the variance V(x) is calculated as:
Where
So, the variance V(x) is equal to:
Finally, the standard deviation is calculated as:
