Mathematics

Solve the problem.The table below summarizes the construction cost of a set of homes (excluding the lot cost) along with the square footage of the home's floor space. Find a linear equation that relates the construction cost in thousands of dollars to the floor space in hundreds of square feet by finding the least squares line for the data.

A. y = 7.97x - 13.54 B. y = 7.87x - 13.08 C. y = 8.13x - 12.79 D. y = 8.13x

Use Stokes' Theorem to calculate the circulation of the field F around the curve C in the indicated direction.F = 3xi + 2xj + 7zk; C: the cap cut from the upper hemisphere x2 + y2 + z2 = 16  by the cylinder 

A. 4? B. 3? C. 8? D. 2?

Solve using the elimination method. Use a graphing calculator to check your answer. 2x + 8y = 10 4x = 8 - 16y
