You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the
Vedmedyk [2.9K]

Answer:

416025

Step-by-step explanation:

For confidence interval of 99%, the range is (0.005, 0.995). Using a z-table, the z-score for 0.995 is 2.58.

Margin of error = 0.2% = 0.002.

Proportion is unknown. So, worse case proportion is 50%. p = 50% = 0.5.

\\ n = \left(\frac{\texttt{z-score}}{\texttt{margin of error}} \right )^2\cdot p\cdot (1-p) \\ = \left(\frac{2.58}{0.002} \right )^2\cdot 0.5\cdot (1-0.5)=416025

So, sample size required is 416025.

Any multiple of (-2x+3y=18) would constitute an "other equation" forming a system with an infiinite number of solutions.  The reason for that is that the two equations would be "dependent."

On the other hand, looking at the system

<span>-2x+ 3y= 18
</span><span>-2x+ 3y= 19

we see that there is no solution.  Why?  Because -2x + 3y cannot equal 18 and 19 at the same time.  You'd have two non-intersecting, parallel lines.
