Una revista publica tres columnas denominadas “Ciencia” (A), “economía” (B) y “entretenimiento” (C). Los hábitos de lectura de un lector seleccionado al azar con respecto a estas columnas están en la tabla adjunta. Determine cuál es Probabilidad que lea B si también lee A o C . Seleccione una respuesta *

6 hours 48 min

step-by-step explanation:

68÷5=13.6

13.6×30=408min=6 hours 48 min.

hope to and hope that my answer is brainliest.(follow me )

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

the first option is the answer.

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
