Una fabrica produce botellas en jna linea con tres Maquinas A, B, C. Si fe un lote de 20 botellas, 8 fueron producidas por la maquina, A, 6 por la maquina B y 6 por la C y extraemos aleatoriamente una botella de ese lote. Clacule la probabilidad de que la botella haya sido producida por la máquina A y C.

step-by-step explanation:

|ab| = 1.4 = 4

h = 1.4 = 4

a(abc) area = 4.4 = 16/2 = 8

area of abc = 8 cm^2

good luck ! ; )

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
