We know that
the formula in solving residual is shown below:
[Residual value] = [Observed value] - [predicted value]
so
[Observed value]=25
[predicted value]=27.745
[Residual value]= 25 - 27.255----------> -2.745
Residual values = -2.745
the answer is the option D) -2.745
Answer:
Write the written problem into an equation to get:
3x +2 = 5x -4
To solve:
Add 4 to each side:
3x+6 = 5x
Subtract 3x from each side:
2x = 6
Divide both sides by 2:
x = 6/2
x = 3
Step-by-step explanation:
Slope intercept is y = mx + b
b is 1470
2x + 3y = 1470
2x (-2x) +3y = 1470 - 2x
3y = -2x + 1470
3y/3 = (-2x + 1470)/3
y = -2/3x + 490
hope this helps
