Solve the System A) No Solution; Inconsistent
B) $\{ ( - 2 , - 6,1 ) \}$

question 23

Multiple Choice

Solve the system. If a system has one unique solution, write the solution set. Otherwise, determine the number of solutions to the system, and determine whether the system is inconsistent, or the equations are dependent.
- $$\begin{aligned}x - \frac { 3 } { 4 } y + \frac { 5 } { 4 } z & = \frac { 15 } { 4 } \\- \frac { 1 } { 4 } x + \frac { 1 } { 2 } y + \frac { 1 } { 8 } z & = - \frac { 19 } { 8 } \\- \frac { 5 } { 2 } x + \frac { 9 } { 2 } y + z & = - 21\end{aligned}$$

• A) No solution; inconsistent
• B) \(\{ ( - 2 , - 6,1 ) \}\)
• C) \(\{ ( 0,0,0 ) \}\)
• D) \(\{ ( 2,1,2 ) \}\)

Definitions:

One-Tailed Test

A statistical test that determines the probability of the observed data under the assumption that one end of the probability distribution is scrutinized.

Two-Tailed Test

A statistical hypothesis test in which the critical area of a distribution is two-sided and tests whether a sample is either greater than or less than a certain range of values.

Null Hypothesis

A statement suggesting that no statistical significance exists in a set of observations.

Alternative Hypothesis

A statement that contradicts the null hypothesis and indicates that there is an effect or a difference.
