What factors affect the sale price of oceanside condominium units? To answer this question, the following data were recorded for each of the n = 105 units sold at auction: y = sale price (in thousands of dollars) %3D X1 floor height (1, 2, 3, .., 8) X2 = 1 is ocean view; 0 is bay view The least squares prediction equation is y = 17.770 - 0.073 x1 +3.137 x2. %3D Interpret the estimated effect of floor height. Expected sale price increases by $0.73 for each one floor increase in floor height for the same view type. The correlation between selling price and floor height is -0.073. Expected sale price increases by $73 for each one floor increase in floor height for the same view type. Expected sale price decreases by $0.73 for each one floor increase in floor height for the same view type.

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…

Geometry is the branch of mathematics that deals with flat surfaces like lines, angles, points, two-dimensional figures, etc. In Euclidean geometry, one studies the geometrical shapes that rely on different theorems and axioms. This (pure mathematics) ge…

In a two-dimensional plane, a line is simply a figure that joins two points. Usually, lines are used for presenting objects that are straight in shape and have minimal depth or width.
