In a multiple regression model, which of the following is true?
group of answer choices:
o the coefficient of determination will be equal to the square of the highest correlation in the correlation matrix.
o adding variables that have a low correlation with the dependent variable will cause the r-square value to decline.
o the sum of the residuals computed for the least squares regression equation will be zero.
o the adjusted r-square might be higher or lower than the value of the r-square.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

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

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

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

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
