La basura que se genera cada año en las ciudades de cierto país está aumentando. La basu- ra generada, en millones de toneladas, fue de 205,2 en 1990 y de 220,2 en 1998. a) Suponiendo que la cantidad de basura generada en esas ciudades es una función lineal del tiempo, hallar una fórmula para tal función. b) Usar la fórmula encontrada en a) para pronosticar la cantidad de basura que será generada en el año 2020.

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

i need the options

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

if you was gonna solve for a, a is a   < -12
