Answer:
Explanation:
There are only two mutually exclusive possibilities for each complex electronic system: being <em>defective</em> or being <em>not defective</em>:
- Number of complex electronic systems: 7
- Nmber of defective systems: 2
- Number of not defective systems: 5
<em>Probability </em>that no defective systems are found in the sample is the equal to the probability of selecting them consecutively without replacement and finding each one is not defective:
- Porbability the first is not defective × probability the second is not defective
- 5/7 × 4/6 = 20/42 = 10/21
Answer:
Step-by-step explanation:
An eigenvalue of n × n is a function of a scalar considering that there is a solution (i.e. nontrivial) to an eigenvector x of Ax =
Suppose the matrix
Thus, the equation of the determinant (A - 1) = 0
This implies that:
Hence, the eigenvalues of the equation are
Also, the eigenvalues can be said to be complex numbers.
