Answer:
Option A) increase or stay the same
Step-by-step explanation:
Coefficient of Determination:
- It is interpreted as the proportion of the variance in the dependent variable that is predictable from the independent variable.
- The coefficient of determination is the square of the correlation between predicted y scores and actual y scores.
- If coefficient of determination is 0 means that the dependent variable cannot be predicted from the independent variable.
- If coefficient of determination is 1 means the dependent variable can be predicted without error from the independent variable.
- One problem with the coefficient of determination is that it always increases whenever we add a new independent variable
Thus, option A) is the correct answer.
Prime factors of 4,725 are 3, 5 and 7
Answer:
Like terms
Same number of equations as unkowns
Step-by-step explanation:
To add linear equations you need the amount of equations to match the number of unknowns.
The equations must have like terms.
All like terms will be added to each other and might even cancel out and solve one term if equal terms have opposite signs.
F(x+1) = (x + 1)^3
= 3x + 3
= 3(0) + 3
= 3
I think is 3
Answer:
x = 1/2 or 0.5
Step-by-step explanation:
5x - 2(2x-2) = 2(3x - 1) + 7/2
= 5x - 4x + 4 = 6x - 2 + 7/2
= 5x + 4 = 10x - 2 + 7/2
= 5x + 6 = 10x + 7/2
= 5x + 2.5 = 10x
= 2.5 = 5x
Thus, x = 1/2 or 0.5
