The mean weight of an adult is 65 kilograms with a standard deviation of 13 kilograms. If 92 adults are randomly selected, what is the probability that the sample mean would differ from the population mean by greater than 1.9 kilograms? Round your answer to four decimal places.

\[ \frac{11}{45} \] Yukarıdaki rasyonel sayının ondalık gösterimi aşağıdaklerden hangısidır? \( \begin{array}{llll}\text { A) } 0.24 & \text { B) } 0.24 & \text { C) } 0.24 & \text { D) } 0.204\end{array} \)

Radon-222 decays at a continuous rate of \( 17.3 \% \) per day. How much will 180 mg of Radon- 222 decay to in 4 days? NOTE: Round your answer to 4 decimal places.

e the system of equations by the addition method. If a system contains decimals, you may want to first clear the equation of decimals. \( \left\{\begin{array}{l}0.06 x+0.06 y=0.24 \\ -0.1 x+0.7 y=2.4\end{array}\right. \) ect 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; \( \{(x, y) \mid 0.06 x+0.06 y=0.24\} \) or \( \{(x, y) \mid-0.1 x+0.7 y=2.4\} \). C. There is no solution; \( \{ \) or \( \varnothing \).

Solve the system of equations by the addition method. If a system contains fractions, you may want to clear the equation of fractions. \( \begin{array}{l}\frac{21}{5} x-y=\frac{4}{5} \\ 7 x+\frac{y}{2}=\frac{11}{5}\end{array} \) 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.) C. There are infinitely many solutions; \( \left\{(x, y) \left\lvert\, \frac{21}{5} x-y=\frac{4}{5}\right.\right\} \) or \( \left\{(x, y) \left\lvert\, 7 x+\frac{y}{2}=\frac{11}{5}\right.\right\} \) Co solution; \( \{0 \) or \( \varnothing \).
