Answer:
The sum of the squared residuals
Step-by-step explanation:
If you sum the residuals, you would get 0
if you sum of the absolute values of the residuals you wouldn't be doing "least-squares regression"
The influence of outliers D The slope is another metric that has nothing to do in creating the regression line
Answer:
x < 3
Step-by-step explanation:
Apply distributive property on the left of the inequality to get rid of the parenthesis:
8+4x > 5x+5
subtract 4x from both sides to group all terms with x on the right:
8 > 5x-4x+5
8 > x +5
Now subtract 5 from both sides to collect all numerical terms on the left:
8 - 5 > x
3 > x
Therefore the solution to the inequality are of those real numbers strictly smaller than 3.
The inequality can be written as x < 3 or also as we had it initially: 3 > x
Notice that the opening of the angle symbol is always facing the number 3 , meaning that 3 is the larger of the two numerical objects that are compared.
Answer: 5
Explanation: The square root of 100 is 10. The square root of 4 is 2.
10/2 = 5
Answer:
21
Step-by-step explanation:
1.
a
y = 5/2x - 3...slope = 5/2
5x = 2y - 4
2y = 5x + 4
y = 5/2x +2...slope = 5/2
both equation has same slope = 5/2 so the lines are parallel
b.
2x + 8y = -24
8y = -2x - 24
y = -1/4x - 3...slope = -1/4
48y = -12x -144
y = -1/4 -3...slope = -1/4
both equation has same slope = -1/4 so the lines are parallel
c.
2x-7y = -56
7y = 2x +56
y =2/7x + 8...slope = 2/7
7x +2y = 8
2y = -7x + 8
y = -7/2x + 4...slope = -7/2
first equation has slope = 2/7 and 2nd equation has slope = -7/2...so the lines are perpendicular
2.
A. y = 13
B. y = -2/3x - 2/3 ....slope = -2/3
C. 4x-7y = 56
7y = 4x - 56
y = 4/7x - 8 ...slope = 4/7
D.2x - 4y = -10
4y = 2x +10
y = 1/2x + 5/2....slope = 1/2
------------------------------------------------------
A line perpendicular to -3x + 2y = 8
-3x + 2y = 8
2y = 3x +8
y = 3/2 x +4 ....slope = 3/2
This answer is B
.............................................
a line parallel to 2y -x = 2
2y = x +2
y = 1/2x + 1 ...slope = 1/2
This answer is D
..............................
a line perpendicular to x = -13
answer is A. y = 13
-------------------------------------------
a line parallel to 16x = 28y so
y = 16x/28
y =4/7x ...slope = 4/7
This answer is C
