Answer:

Step-by-step explanation:

The null hypothesis is described as the default hypothesis while the alternative hypothesis us always tested against this null ie the opposite of the null hypothesis.

In this case study, Let the proportion of houses that have home security be p

Thus, the null hypothesis is proportion of houses that have home security is 45% : p = 45%

The alternative hypothesis is proportion of houses that have home security is different than 45%: p =/ 45%

1. Solve the following system using the substitution, elimination, or graphing method for the y coordinate.
AlekseyPX
\bf \begin{cases}
\boxed{x}=-4y+3\\
-x-4y=-3\\
-----------\\
-\left( \boxed{-4y+3} \right)-4y=-3
\end{cases}
\\\\\\
4y-3-4y=-3\implies \stackrel{\textit{another way of saying the equations are identical}}{0=0}

so the 2nd equation is really the first equation in disguise.

since both equations are the same, that means if you graph them, is just one line pancaked over the other, and the solutions points is every single one on each, namely infinitely many solutions.
