Answer:
x = -3, y = -3.5. As an ordered pair it is (-3, -3.5).
Step-by-step explanation:
9x − 4y = −13
9x − 2y = -20
Subtract:-
-2y = 7
y = -3.5.
Substitute for y in the first equation:
9x - 4(-3.5) = -13
9x = -27
x = -3.
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
Point G cannot be a centroid because GE is wider that JG or JG is shorter than GE. So in this diagram GE is wider than JG with 10 cm and 5 cm respectively based on this information Point G cannot be a centroid of triangle HJK. So the answer is point G cannot be a centroid because JG is shorter than GE.
Answer:
66 ft
Step-by-step explanation:
L ∝ n
L = kn , k -> number of sections
Length of 3 sections= 18 ft
3n = 18
n = 18/3
n = 6 ft
Length of 1 section of fence = 6 ft
Length of 11 sections of fence = 6* 11 = 66 ft
Answer:
Step-by-step explanation:
Given:
AC = 5
BC = 6
DB = 4.2
∠ACD ≅ ∠BCD
AD = 
∵ ∠ACD ≅ ∠BCD
∴ CD is the angle Bisector of ∠ ACB
We know that, from angle bisector theorem that,
The angle bisector of an interior angle of a triangle divides the opposite side in two segments such that the two segments are proportional to the other two sides of the same triangle.
Therefore, the sides that are in proportion are given as:
Substituting the given values we get:
Therefore, the value of is 3.5.
