Find the interquartile range (IQR) of the data set. 1,1,3,4,4,5,5,5,6,7,9
iragen [17]
The interquartile range is 3
Let each side perpendicular to the wall be x
The parallel to the wall will be 320-2x
the area will be:
A(x)=x(320-2x)
A(x)=320x-2x^2
This is a quadratic with a =-2 and b=320
Maximum area will occur where x=-b/2a
=-320/(-2*2)
=80 ft
thus the width will be 80 ft and the length will be:
length=320-2*80=160 ft
5.4 T=46.9
It would take 46.9 minutes to fill up the pool
Answer:
x = 
Step-by-step explanation:
Cos 45= 12/x
x=12/Cos 45


x=
