Develop a multiple regression model to predict the price of a home based on square footage and location. (Price is in thousands of dollars.) Include a dummy variable to represent the location (1 = on cul-de-sac, 0 = not on cul-de-sac). The first few lines of data are below: Home Price SqFt Cul-de-sac

What is the interpretation of Ra²?
a. 91.32% of the variation in Price is being explained by the X’s.
b. 91.32% of the variation in Price is being explained by the X’s once we have taken a penalty for the # X’s using.
c. 92.23% of the variation in Price is being explained by the X’s.
d. 92.23% of the variation in Price is being explained by the X’s once we have taken a penalty for the # X’s using.

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

a. (14,375+570)(5.3) b. 158,417$

step-by-step explanation:

a. you are basically just setting up the equation. f= amount of debt hence 14,375. g= how much she is borrowing from her parents weekly hence 570 and t= the interest on her debt. creating the equation.

b.   14,375+570= 14,945

      14,945 x 5.3 = 79,208.5

      79,208.5 x 2(years) = 158,417(answer)

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
