Step-by-step explanation:
Given the following :
Laps - - - - - - - - 5 - - - 6 - - - 7 - - - 8 - - - 9
Total time - - - 25 - - 28 - - 29 - - 30 - - 32
Using online graphing tool:
The y - axis named dependent variable represents the total time taken.
The x-axis, represents the number of laps.
The equation of the trend line attached to the plot is in the form :
y = mx + c
y = 1.6x + 17.6
Where y = total time taken
x = number of laps
m = 1.6 = gradient of the line (change in y / change in x)
C = 17.6 = intercept (whee the trndline intersects the y-axis).
Answer:
Step-by-step explanation:
21: 9/15+1/4= 0.85, if you turn that into a percent it is 85%

Answer:
Step-by-step explanation:
"length is 4 meters less than 2 times the width"
L = 2W+4
"perimeter is 40 meters"
2L+2W = 40
L+W = 20
(2W+4) + W = 20
3W + 4 = 20
W = 16/3 meters
