Question

Given that sigma_i = 1^50 X_i = 250, sigma_i = 1^50 Y_i = 700, sigma_i = 1^50 X_i Y_i = 1200, and sigma_i = 1^50 X_i^2 = 1500, find the following summations: a. sigma_i = 1^50 (5X_i - 8Y_i + 16) b. sigma_i = 1^50 (2X_i + 8Y_i) (X_i - 20) A county's tax office has a list of all 15,000 taxable properties in the county. each property, the list has the assessed market value of the property, V_i, and the amount of any special tax on the property, S_i. The property tax rate in the county is 1.2% of the assessed market value. The total amount of taxed owed to the county is the property tax plus the special tax. Write a formula using summation notation for the total amount of tax revenue that the county is owed by the owners of all 15,000 taxable properties. Round each of the following to four significant digits. a. 0.003666666 b. 36/7000
