Answer:
<h3>
The option B) is correct.</h3><h3>
That is the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible is correct answer</h3>
Step-by-step explanation:
Given that " The least-squares regression line "
The least-squares regression line is <u>the line that makes the sum of the squares of the vertical distances of the data points from the line (the sum of squared residuals) as small as possible.</u>
Therefore option B) is correct
Answer :
$52.50 - x
Step-by-step explanation:
8.75*6 = 52.5
Price of the book = x
$52.50 - x
Answer:
x=21°
Step-by-step explanation:
64°=3x+1 --------- because vertically opposite angles are equal
63=3x
x= 63/3
x=21°
Answer:
(-3/2, 5/2)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
3x + y = -2
5x - y = -10
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Eliminate y</em>
- Add 2 equations together: 8x = -12
- Divide 8 on both sides: x = -12/8
- Simplify fraction: x = -3/2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: 3x + y = -2
- Substitute in <em>x</em>: 3(-3/2) + y = -2
- Multiply: -9/2 + y = -2
- Add 9/2 on both sides: y = 5/2
