Answer:

x = -1

Step-by-step explanation:

-14 + 3x + 30 = 14x +28 +x  [distributive property]

-14+30 +3x = 14x +x +28   [gather like terms on each side]

16 + 3x = 15x + 28  [combine like terms]

16 = 12x + 28  [subtract 3x from each side to gather like terms]

-12=12x  [subtract 28 from both sides]

-1 = x [divide both sides by 12 to solve for x]

A manufacturer makes bags of popcorn and bags of potato chips. The average weight of a bag of popcorn is supposed to be 3.06 oun
alexandr1967 [171]

Answer:

The potato bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn chip bag assembly line.

Step-by-step explanation:

Popcorn mean= μ`1= 3.06

Popcorn St. Dev= σ1= 0.02

Potato Mean= μ`2= 5.05

Potato St. Dev= σ2= 0.05

Finding the z score

z= x- u / σ

Popcorn z= 3.06- 3.03/0.02= 1.5

Potato Z= 5.05-5.07/0.05= -0.4

The mean is taken to be at zero ( 0)  therefore difference of 0.4 is less than a difference of 1.5

Choice 3 is the best option .
