An internet service provider has two connection lines for its customers. eighty percent of customers are connected through line i, and twenty percent are connected through line ii. line i has a gamma connection time with parameters α = 3 and λ = 2 min−1 . line ii has a uniform(a, b) connection time with parameters a = 20 sec and b = 50 sec. compute the probability that it takes a randomly selected customer more than 30 seconds to connect to the internet.

first one is a: renaming a fraction. second one is c: de-c

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
