Se tiene una caja con seis pelotas de colores amarillo, verde, rojo, café, blanco y negro. El experimento es tomar tres pelotas al azar, en el que si importa el orden en el que se toman las pelotas. Utiliza las permutaciones para encontrar el total de resultados posibles y así calcular la probabilidad para los siguientes eventos. a) Obtener una pelota negra la primera vez que se toma una pelota y sacar una pelota blanca la segunda vez que se extrae una pelota. b) Obtener una pelota amarilla la tercera vez que se toma una pelota.

S. 11 Calculate speed, distance, or time: word problems TLB Greta rented an e-bike to ride while on vacation. On the bike, she traveled 4,800 feet in 3 minutes. What was Greta's speed? Write your answer as a whole number or decimal.

Radon-222 decays at a continuous rate of \( 17.3 \% \) per day. How much will 130 mg of Radon- 222 decay to in 4 days? NOTE: Round your answer to 4 decimal places.

\( a)<5>\sqrt {9<6

What value of \( z \) divides the standard normal distribution so that half the area is on one side and half is on the other? Round your answer to two 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 \( \varnothing \).
