Areal estate agent would like to predict the selling price of a single-family house by predicting the price (in thousands of dollars) based on the square footage (in 100 square feet). if the lsrl for the data is ŷ = 3.8785x + 18.3538. predict the price of a 3000 square foot house (in thousands of dollars).

$134.7088 thousand dollars

Step-by-step explanation:

The given equation of Least Squares Regression Line is

where, is predicted selling price of the house (in thousands of dollars) based on the square footage (in 100 square feet).

We need to find the price of a 3000 square foot house (in thousands of dollars).

3000 = 30 × 100

3000 square foot = 30 square footage (in 100 square feet).

Substitute x=30 in the given equation.

Therefore, price of a 3000 square foot house is $134.7088 thousand dollars.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
