Solve the System by Using Substitution $$\left( \begin{array} { l } y& =& \frac { 2 } { 3 } x &- &4 \\5 x &- &4 y& =& 9\end{array} \right)$$

question 72

Short Answer

Solve the system by using substitution. $$\left( \begin{array} { l } y& =& \frac { 2 } { 3 } x &- &4 \\5 x &- &4 y& =& 9\end{array} \right)$$ If the equations of the system are dependent, or if a system is inconsistent, so indicate. In those cases enter dependent or inconsistent . Otherwise, enter your answer as an ordered pair ( x , y ).

Definitions:

T Distribution

A type of probability distribution that arises when estimating the mean of a normally distributed population in situations where the sample size is small and the population standard deviation is unknown.

Confidence Interval

A range of values, derived from the sample data, that is likely to contain the value of an unknown population parameter.

Population Means

The average of a set of characteristics (such as measurements or counts) of the entire population.

Statistically Significant

Indicates that the observed results are unlikely to occur by chance, based on a predefined significance level.
