Answer:
A. the mode.
Step-by-step explanation:
Mean
Sum of all values divided by the number of values, so is affected by an outlier present in the data-set.
Standard deviation:
Square root of the sum of the differences squared between each value and the mean, divided by the sample size. As it's related to the mean, it is affected by an outlier.
Range:
Subtraction of the largest value of the data-set by the smallest value, and thus, is also affected by an outlier.
Mode
Value that appears the most often in the data-set, and thus, not affected by an outlier, which means that the correct answer is given by option A.
Answer:1. Angle BDA and angle BEA are the same angles.
2.AB is the bisector of the quadrilateral (It splits it in half turning it into two triangles that are exactly the same).

Answer:
C
Step-by-step explanation:
Given the 2 equations
6x + 2y = 8 → (1)
12x + y = 22 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 24x - 2y = - 44 → (3)
Add (1) and (3) term by term, thus eliminating y
- 18x = - 36 ( divide both sides by - 18 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
6(2) + 2y = 8
12 + 2y = 8 ( subtract 12 from both sides )
2y = - 4 ( divide both sides by 2 )
y = - 2
Solution is (2, - 2 ) → C

Answer:
(4,-4)
Step-by-step explanation:
To find the point which is not a solution, identify the point which is not in the set of solutions. This will be a point which is not in the shaded section of its graph. Graph the inequality by shifting the parent function down 3 units and to the left 4 units. Then flip the graph because of the negative out front. See the attached graph. All the points lie in the shaded except for (4,-4).
