Answer:
C
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
A(3, 4 ) → A'(- 3, 4 )
Since the point A and it's reflection lie on a horizontal line then
distance between = | 3 + 3 | = | 6 | = 6
There are 13 numbers here:
30, 30, 31, 32, 42, 49, 58, 58, 67, 67, 69, 78, 90.
The median number is the 7th number, which is 58.
increasing
This line is increasing
The slope is greater than 0 so the line is going up
2.304
Add 0.234 and 2.07 left to right with 0.234 on the top and 2.07 on the bottom.
