The variance of a population can be completed with the following steps:
Compute the mean of the measurement.
Take the difference between each element in the population and the mean.
Square that difference.
Sum the squares of the difference.
Finally, divide by the number of measurements in the population.
Hope this helped!!!XD
Answer:
Area=77
Step-by-step explanation:
P=36
P=2l+2w
l=w+4
P=2(w+4)+2w
P=2w+8+2w
P=4w+8
36=4w+8
28=4w
w=7
l=7+4
l=11
A=lw
A=77
125
