1a.
Show from first principles, i.e., by using the definition of linear independence,
that if μ = x + iy, y ̸= 0 is an eigenvalue of a real matrix
A with associated eigenvector v = u + iw, then the two real solutions
Y(t) = eat(u cos bt − wsin bt)
and
Z(t) = eat(u sin bt + wcos bt)
are linearly independent solutions of ˙X = AX.
1b.

Reduce the system
(D2 + 1)[x] − 2D[y] = 2t
(2D − 1)[x] + (D − 2)[y] = 7.
to an equivalent triangular system of the form
P1(D)[y] = f1(t)
P2(D)[x] + P3(D)[y] = f2(t)
and solve.

Identify each of the following statements as true or false in relation to confidence intervals (CIs).
Note: 0.5 marks will be taken away for each incorrect answer. The minimum score is 0.

True False
A 95% CI is a numerical interval within which we are 95% confident that the true mean μ $μ$ lies.
A 95% CI is a numerical interval within which we are 95% confident that the sample mean x¯¯¯ $\bar{x}$ lies.
The true mean μ $μ$ is always inside the corresponding confidence interval.
For a sample size n=29 $n = 29$ , the number of degrees of freedom is n=30 $n = 30$ .
If we repeat an experiment 100 times (with 100 different samples) and construct a 95% CI each time, then approximately 5 of those 100 CIs would not $n o t$ contain the true mean 𝜇.

In the majority of cases, students dealing with upper-level Math questions will have to solve not only numerical problems or equations but also verbal tasks. The answers that are provided below free of charge will help you to find solutions to your questions that are dealing with more advanced Maths problems. Remember that one must look into analysis and evaluation of original instructions, which is why upper-level Maths requires more thinking as you study questions and see how the answers have originated. The trick is to see similarities in solutions that are being provided as it always helps.
