9x=81.16
x=9.16
x=144
Let the length be x and the width be y:
Area=x*y=600
thus
x=600/y
Perimeter=2(L+W)
100=2(x+y)
substituting the value of x we obtain:
100=2(600/y+y)
solving for y we shall have:
50=600/y+y
50y=600+y^2
thus
y^2-50y+600=0
solving the quadratic we obtain:
y=20 or y=30
thus the length=30 ft and the width=20 ft
The correct order to determine if the results are significant are as follows:
1. Randomly separate the employee's individual results into two groups.
2.Calculate the mean of each group.
3. Calculate the difference of the means
4. Run the experiment many times
5. Calculate the probability of a difference of 5.
These steps are used to determine statistical significance by finding difference of means.
