[Done] Find the solution set of the following linear system. Identify inconsistent systems and dependent equations. [tex]\left\{\begin{aligned} x-3 y-z & = -9 \\ -x+8 y-4 z & = 24 \\ 2 x-15 y+7 z & = -45 \end{aligned}\right.[/tex] Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. The system is consistent and the solution set is {[tex]\([/tex] $\square$, $\square$, $\square$ )}. (Simplify your answers.) B. The system is consistent and dependent. The solution set is the set of all ordered triples {([tex]$\square$[/tex], [tex]$\square$[/tex], z) }, where (Type an expression using z as the variable. Simplify your answer.) C. The system is inconsistent.

[Done] Consider the following data on some weak acids and weak bases: Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2 the solution that will have the next lowest pH, and so on.

[Done] Calculating Binomial Probabilities Leigh plays a game at a fundraiser for which there is a probability of 0.2 that she wins. She plans to play this game times. What is the probability that she wins exactly 1 time? Enter your answer to 4 decimal places. [tex]\begin{array}{l} P(X=k)=\binom{n}{k} p^k(1-p)^{n-k} \\ P(X=1)=\square \end{array}[/tex]

[Done] Type the correct answer in the box. The solubility of calcium carbonate is [tex]$14 \frac{\text { milligrams }}{\text { liter }}$[/tex]. This rate means that 14 milligrams of calcium carbonate can dissolve in 1 liter of water. How much water would be required to fully dissolve 11 grams of calcium carbonate? Express your answer to the correct number of significant figures. One milligram is equal to 0.001 grams. It would take $\square$ liters of water to fully dissolve 11 grams of calcium carbonate.
