d) $128.65
Step-by-step explanation:
The table format from the question can be properly expressed as :
Coefficients Standard Error t Statistic p value
Intercept 39.14942 22.30182 1.755436 0.109712
x 1.792312 0.407507 4.398234 0.001339
Source df SS MS F = 29.51443
Regression 1 16850.99 16850.99 19.34446 = 0.682478
Residual 9 7839.915 871.1017
Total 10 24690.91
For a rural household with $90,000 annual income, Abby's model predicts weekly grocery expenditure of:_________.
The estimated regression equation is as follows:
Expenditure (y) = 39.15 + 1.79 x
For a rural household with $90,000 annual income; the independent variables will assume the following values
x = 50
Thus; the estimated groceries expenditure is computed from the above regression equation by replacing the values of the independent variables;
This can be expressed as:
y = 39.15 + 1.79 (50)
y = 39.15 + 89.5
y = $128.65
So remember that area of a rectangle is a = bh. In this case, our sides are 2 and n - 3 (three less than unknown number) and our area is 22. Using our info, we can form the equation: . From here we can solve for n.
Firstly, foil 2(n-3):
Next, add 6 on both sides of the equation:
Next, divide both sides of the equation and your answer will be 14 = n. In context, the value of the unknown number is 14 in.
