Answer:
P(Type II error) = 0.1
Step-by-step explanation:
In statistics, the formula for power of a hypothesis is given by;
Power = 1 - P(Type II error)
Where P(Type II error) is the probability of making a Type II error.
We are told that the power is 0.9.
Thus;
0.9 = 1 - P(Type II error)
Making P(Type II error) the subject gives;
P(Type II error) = 1 - 0.9
P(Type II error) = 0.1
The question is basically asking you to get "h" to one side by itself, so...
v=1/3Bh
v/3=Bh
3v/B=h
Increasing the length by
we have the new expression for the length as
Increasing the width by
, we have the new expression for the width as
Perimeter of a rectangle is given by adding all the sides, so we have

A=LW and L=W+9 so
A=(W+9)W
A=W^2+9W
W^2+9W-A=0, since A=220
w^2+9w-220=0
w^2+20w-11w-220=0
w(w+20)-11(w+20)=0
(w-11)(w+20)=0
Since w>0
W=11 ft, and since L=W+9
L=20 ft
