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
1. X=2+1/2y+1/2z
2. X=-1+2y+z
3. X=16/3-1/3y-1/3z
Answer:
Triangles ABC and MNO are similar by SSS
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional
In this problem
If this problem the corresponding sides are
AB and MN
BC and NO
AC and MO
Verify if the corresponding sides are proportional
substitute the given values
----- is true
so
When two triangles have corresponding sides with identical ratios , the triangles are similar by SSS Similarity
therefore
Triangles ABC and MNO are similar by SSS
Answer:
50%
Step-by-step explanation:
Answer: the option A.
The elimination method consist is adding the two equations in a way that one variable be eliminated..
In order to do that you might have to manipulate on of the equations prior to add the two equations.
In this case, ff you multiply the second equation by - 1 you will get
- x - y = - 4
which you can add to the first equation
2x + y = 8 to eliminate the y.
