Answer:

m=\frac{5}{7}

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-9, -10)

Point (-2, -5)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{-5+10}{-2+9}
  2. Add:                              m=\frac{5}{7}

And we have our final answer!

A realtor collects the data set given in DS 12.2.4 concerning the sizes of a random selection of newly constructed houses in a c
Yuliya22 [10]

The table is missing in the question. The table is attached below.

Solution :

Let X = appraised value

    Y = area (square feet)

The regression line is given by :

$\hat y = b_0+b_1X$

$b_1=\frac{n\sum XY-\sum X \sum Y}{n \sum X^2-(\sum X)^2}$

   $=\frac{15(5964990)-(2157)(33370)}{15(404799)-(2157)^2}$

  $=12.3267$

$b_0=\frac{\sum Y}{n}-b_1\frac{\sum X}{n}$

   $=\frac{33370}{15}-\left(12.3267 \times \frac{2157}{15}\right)$

  $b_0=452.0841$

The regression line is :

$\hat Y = 452.0841+12.3267 X$

To estimate the error variance, we have:

Error variance, $\sigma =\sqrt{\frac{\sum (Y-\hat Y)^2}n-2{}}$

                           $=\sqrt{\frac{587682.3}{15-2}}$

                            $=212.6178$
