What are the determinants for solving this linear system? 5x + 3y = 17 −8x − 3y = 9 |A| = |Ax| = |Ay| =
valentina_108 [34]

For this case we have the following system of equations:

5x + 3y = 17\\-8x - 3y = 9

We can Rewrite the system of equations of the form:

Ax = b

Where,

A: coefficient matrix

x: incognita vector

b: vector solution

We have then:

A=\left[\begin{array}{ccc}5&3\\-8&-3\end{array}\right]

x=\left[\begin{array}{ccc}x\\y\end{array}\right]

b=\left[\begin{array}{ccc}17\\9\end{array}\right]

Then, the determinant of matrix A is given by:

|A|=(5)(-3)-(3)(-8)\\

|A|=-15+24

|A|=9

Answer:

The determinants for solving this linear system are:

|A|=9

antiseptic1488 [7]

The 90% confidence interval is between R96.94 and R105.06

The confidence (C) = 90% = 0.9, Mean (μ) = 101, standard deviation (σ) = 39, sample size (n) = 250

α = 1 - C = 1 - 0.9 = 0.1

α/2 = 0.1 / 2 = 0.05

The z score of α/2 corresponds with the z score of 0.45 (0.5 - 0.05) which is equal to 1.645

The margin of error (E) is given by:

E=Z_\frac{\alpha }{2} *\frac{\sigma}{\sqrt{n} } \\\\E=1.645 *\frac{39}{\sqrt{250} } =4.06

The confidence interval = μ ± E = 101 ± 4.06 = (96.94, 105.06)

Therefore the 90% confidence interval is between R96.94 and R105.06
