Which of the following is a reason why you can not make a statistical inference on the population?" The answer is The wrong sampling method was used.
Answer:
D
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
That is the x- coordinate remains unchanged while the y- coordinate is the negative of the original y- coordinate.
Given
A(- 3, 5 ) → A'(- 3, - 5 )
B(2, 8 ) → B'(2, - 8)
C(- 4, - 5 ) → C'(- 4, 5 )
The rule for reflection in the x- axis has been applied here → D
80 Because the numbers are going up by 10
Answer:
Option (D)
Step-by-step explanation:
Subtraction property of equality tells that whatever subtracted from one side of the equation must be subtracted from the other side.
If x + 2 = 2,
By the property of subtraction of equality,
x + 2 - 2 = 2 - 2
x = 0
But in the given question,
shows the addition property of equality in step (2)
Therefore, subtraction property of equality was not applied.
Option (D) will be the answer.
