standard error of the mean = 1.6960

Mean (\overline{X}) = 53 minutes

Standard deviation ( s ) = 53.9 minutes

n = 1010

standard error of the mean  =  

\sigma _{\overline{X}}    =   \frac{s}{\sqrt{n}}

        = \frac{53.9}{\sqrt{1010}}

What shows the volume
Svetllana [295]

Answer:

654 1/2 cm³

Step-by-step explanation:

First the volume of the cylinder, the formula for that is πr²h

Radius is half of diameter so 7/2=3.5

3.5^2=12.25

12.25x22/7=38.5

38.5x15=577.5

Now the cone, the formula for this is πr²h/3

It has the same radius as the cylinder so 3.5^2=12.25

12.25x22/7=38.5

38.5x6=231

231/3=77

Now we add them together to find total volume.

577.5+77=654.5
