Answer:

standard deviation of the distribution = 6.325.

Step-by-step explanation:

i) standard deviation of the population σ = 20

ii) size of sample n = 10.

iii) standard deviation of the distribution = \frac{\sigma}{\sqrt{n}} = \frac{20}{\sqrt{10}} = \frac{20}{3.162} = 6.325

Natasha_Volkova [10]

Answer:

60 inches long are the sides of the pillars.

Step-by-step explanation:

Given : A small bridge sits atop four cube shaped pillars that all have the same volume. the combined volume of the four pillars is 500 ft cubed.

To find : How many inches long are the sides of the pillars?

Solution :

Refer the attached picture below for Clarence of question.

The volume of the cube is V=a^3

Where, a is the side.

The combined volume of the four pillars is 500 ft cubed.

The volume of each cube is given by,

V=\frac{500}{4}=125\ ft^3

Substitute in the formula to get the side,

125=a^3

a=\sqrt[3]{125}

a=5\ ft

We know, 1 feet = 12 inches

So, 5 feet =5\times 12=60 inches

Therefore, 60 inches long are the sides of the pillars.
