Step-by-step explanation:
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.)

Step-by-step explanation:
Answer:
Step-by-step explanation:
15x + 12 + 10 - 20 = 12
15x + 22 - 20 = 12
15x + 2 = 12
15x = 12 - 2
15x = 10
x = 10/15 which reduces to 2/3
