6... I think.
I hope that this is right
The mean of the sample given by 44,22,11,17,21 will be given by:
![\mu= \frac{\Sigma x_i}{n}](https://tex.z-dn.net/?f=%20%5Cmu%3D%20%5Cfrac%7B%5CSigma%20%20x_i%7D%7Bn%7D)
the sum of x's will be:
44+22+11+17+21
=115
n=5
therefore the mean will be:
μ=115/5
=23
Answer:
525 ft sq.
Step-by-step explanation:
Variable.
Length = 2w+5
Width = w
2(l+w)=100
2(2w+5+w)=100
2(3w+5)=100
6w+10=100
w=15
l=35
15*35=525
