Answer:
The treatment should be stated by the four companies,since it more interested in the quality among each of the companies to be compared.
Step-by-step explanation:
From the example given, Since an electronic company wants to differentiate their cell phones quality to the cell phones from their three main competitors.
If ANOVA is used to determine the average number of defects, then the treatment should be defined for the four companies because it is more interested in comparing the quality among the different companies.
The sum of functions is given as:

In this case we have:
![(f+g)(x)=5x+\sqrt[]{x-1}](https://tex.z-dn.net/?f=%28f%2Bg%29%28x%29%3D5x%2B%5Csqrt%5B%5D%7Bx-1%7D)
The domain of the functions is any number that makes the squared root a real number, then:

Hence the domain of the functions is:
Answer:
<h2>18</h2>
Step-by-step explanation:
The formula of a distance between two points:

We have the points (5, -7) and (5, 11). Substitute:

Mass, hardness, density, luster
Answer:
120°
Step-by-step explanation:
Sum of angles = (n-2)180°, where n is the number of sides.
This is a hexagon, so n=6.
Sum of angles = (6-2)180° = 720°
Each interior angle = 720°/6 = 120°
