Solve the following system of equations. \( \left\{\begin{array}{r}x-2 y+3 z=-1 \\ -2 x+4 y-6 z=2 \\ 3 x-6 y+9 z=-3\end{array}\right. \) Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. There is one solution. The solution is (Type integers or simplified fractions.) B. There are infinitely many solutions. The solution set is \( \{(x, y, z) \mid x-2 y+3 z=-1\} \). C. The solution set is \( \varnothing \).

Solve the following system of equations. \[ \begin{array}{l}3 x+3 y-12 z=9 \\ 2 x+y-z=10 \\ -x-y+4 z=5\end{array} \] Select the correct choice below and, if necessary, fill in the answer boxes to complete your A. There is one solution. The solution is ( (Type integers or simplified fractions.) B. There are infinitely many solutions. The solution set is \( \{(x, y, z) \mid 3 x+3 y-12 z=9\} \) C. The solution set is \( \varnothing \).

Thompson and Thompson is a steel bolts manufacturing company. Their current steel bolts have a mean diameter of 135 millimeters, and a variance of 64 . If a random sample of 46 steel bolts is selected, what is the probability that the sample mean would differ from the population mean by greater than 1.5 millimeters? Round your answer to four decimal places.

Solve the system of equations by the addition method. \( \left\{\begin{array}{l}2 x-y=2 \\ 3 x+y=13\end{array}\right. \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The solution is \( \square \). (Simplify your answer. Type an ordered pair.) B. There are infinitely many solutions; \( \{(x, y) \mid 2 x-y=2\} \) or \( \{(x, y) \mid 3 x+y=13\} \). There is no solution; \( \} \) or \( \varnothing \).

Solve the system by either the addition method or the substitution method. \[ \begin{aligned} \frac{x+4}{2}=\frac{y+15}{5} \\ \frac{x}{2}=\frac{2 y+10}{10}\end{aligned} \] Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The solution is \( \square \). (Simplify your answer. Type an ordered pair.) B. There are infinitely many solutions; \( \left\{(x, y) \left\lvert\, \frac{x+4}{2}=\frac{y+15}{5}\right.\right\} \) or \( \left\{(x, y) \left\lvert\, \frac{x}{2}=\frac{2 y+10}{10}\right.\right\} \). There is no solution; \( \} \) or \( \varnothing \).
