Answer:
i dont understand this question at all
Step-by-step explanation:
Well convert all of them into fourths. 3 1/2 = 3 2/4. Add all the whole numbers 2 + 4 + 3 = 9 and then add the fractions 1/4 + 3/4 + 2/4 = 6/4 = 1 2/4. Finally add the whole number and fraction together, 10 2/4 or 10 1/2.

The answer is 9 it’s a multiple of 3 and is also greater than 6
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.)
