The box plot that would confirm the inference that Linda made would have a minimum value of 20 and a maximum value of 40. Somewhere in the between is the mean. The box plot should have a confidence interval of 95% in order to have the inference valid.<span />
Answer:80ft
Step-by-step explanation:
Answer:
3.5%
Step-by-step explanation:
The volume of a cylinder = 
<em>r</em> = radius of cylinder,
<em>h</em> = height of cylinder
For the non-optimal can,
<em>r</em> = 2.75/2 = 1.375
<em>h</em> = 5.0

<em />
For the optimal can,
<em>d</em>/<em>h</em> = 1,
<em>d</em> = <em>h</em>
2<em>r </em>=<em> h</em>
<em>r</em> = h/2

They have the same volume.
<em />
<em />

(This is the height of the optimal can)
(This is the radius of the optimal can)
The area of a cylinder is
<em />
<em />
For the non-optimal can,

For the optimal can,

Amount of aluminum saved, as a percentage of the amount used to make the optimal cans = 
5=z−4−3
5=z-7
move -7 to the other side
sign changes from -7 to +7
5+7=z-7+7
5+7=z
Answer: z=12
