An electronics company wants to compare the quality of their cell phones to the cell phones from three of their competitors. They sample 10 phones from each of the four companies and count the number of defects for each phone. If ANOVA was used to compare the average number of defects, then the treatments would be defined as: .

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:

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
