Answer:
-5
Step-by-step explanation:
Given the two box plots showing the number of seconds the students completes the 50-meter-dash race before and after the program, we are to determine the difference between the median value of seconds before and after the program.
Median in a box plot is represented by the vertical line that divides the rectangular box in a box plot.
Thus, the median before the program = 15 seconds
The Median after the program = 10 seconds
The median change = 10 - 15 = -5 seconds.
This means, after the program, most of the students now finish the 50-meter-dash faster, about 5 seconds less the former seconds used before the program.
Answer:
Neither
Step-by-step explanation:
1.) has a vertical jump from (4,5) to (4,6), so it is not a linear line.
2.) has a vertical jump from (3,2) to (3,-8) and a horizontal segment from
(3,2) to (9,2)
Therefore there is no correlation between the two lines at all.

Step-by-step explanation:
option a .......
Answer:
Center: (-7, -4)
radius = 4
Explanation:
- Equation: (x + 7)² + (y + 4)² = 16
Circle formula:
(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
- (x - (-7))² + (y - (-4))² = 4²
From this identify:
- h = -7, k = -4, radius = 4
