## Determine value of X and K

- $X$ is between 0.2–0.5.
- Equation: $S = K[XI + (1-X)O]$
- $S$ to be on y-axis and $XI + (1-X)O$ to be on x-axis.
- Calculate $S$ using continuity equation
- Calculate $XI + (1-X)O$ with different values of X ($0.1–0.5$)
- Using the statistics mode of calculator to determine values of slope and R-squared (`MENU` > `6` > `2` ; plot; `OPTN` > `4`)
- Choose $X$ based on max R-squared value, corresponding slope is the value of $K$.
