Answer:
y = -0.85 + 0.09x; $49.82
Step-by-step explanation:
1. Calculate Σx, Σy, Σxy, and Σx²
The calculation is tedious but not difficult.
2. Calculate the coefficients in the regression equation
To two decimal places, the regression equation is
y = -0.85 + 0.09x
3. Prediction
If x = 563,
y = -0.85 + 0.09x = -0.85 + 0.09 × 563 = -0.85 + 50.67 = $49.82
(If we don't round the regression equation to two decimal places, the predicted value is $50.56.)
The expanded answer is 2025m^2+1620m+324

Answer:
3x^2+1.5x-9
Step-by-step explanation:
(f+g) (x)
=f(x)+g(x)
=x/2-3+3x^2+x-6
=3x^2+1.5x-9
Answer:
They are a Pythagorean triple that forms a right triangle
Step-by-step explanation:
a2 + b2 = c2
(5)^2 + (12)^2 = (13)^2
25 + 144 = 169
(13)^2 = 169
A is the answer since if you graph it, it has those points, or you may just simply plug in the x points that are given and see if they equal the y number
