- It can also be used to check the difference between mean of groups.
- It can also be used to check the difference between medians of groups.
- There are many types of ANOVA test: one way, two way, etc
Thus, the correct answer is
Option d) Both (a) and (c)

Answer: 10
Step-by-step explanation Simplifying
2x + 7 = 3(x + -1)
Reorder the terms:
7 + 2x = 3(x + -1)
Reorder the terms:
7 + 2x = 3(-1 + x)
7 + 2x = (-1 * 3 + x * 3)
7 + 2x = (-3 + 3x)
Solving
7 + 2x = -3 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
7 + 2x + -3x = -3 + 3x + -3x
Combine like terms: 2x + -3x = -1x
7 + -1x = -3 + 3x + -3x
Combine like terms: 3x + -3x = 0
7 + -1x = -3 + 0
7 + -1x = -3
Add '-7' to each side of the equation.
7 + -7 + -1x = -3 + -7
Combine like terms: 7 + -7 = 0
0 + -1x = -3 + -7
-1x = -3 + -7
Combine like terms: -3 + -7 = -10
-1x = -10
Divide each side by '-1'.
x = 10
Simplifying
x = 10
