Answer:

a) True

Step-by-step explanation:

The given statement is true.

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}  

where x_i are data points, \bar{x} is the mean and n is the number of observations.  

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

The standard deviation express the variation of data from the mean and therefore, have the same unit as the data like lbs, inches, dollars, etc.

Coefficient of variation on the other hand is the ratio of standard deviation and mean. It is also a measure of dispersion but since it is a ratio, the units cancel each other.

C.V = \dfrac{s}{\bar{x}}

Thus, coefficient of variation is dimensionless.

Thus, it is a relative measure.

What is the volume of a cylinder that has a radius of 4 cm and a length of 8cm
Shkiper50 [21]

Answer:

volume of a cylinder = 401.92cm³

Step-by-step explanation:

to calculate the volume of a cylinder , we will use the formular for finding the volume of a cylinder

volume of a cylinder =  πr²h

given that

height of the cylinder = 8cm

radius of the cylinder = 4cm

volume of a cylinder = π × (4cm)² × 8cm

volume of a cylinder = π × 16cm² × 8cm

volume of a cylinder = π128cm³

value of π = 3.14

volume of a cylinder = 3.14 × 128cm³

volume of a cylinder = 401.92cm³

Factor:<br><br><br>(m+2)^2−(m+2)+mn·(n+2)+2n(n+2)
bazaltina [42]
ANSWER
{(m + 2)}( {n}^{2} + 2n + m + 1)

EXPLANATION

The given expression is

{(m + 2)}^{2} - (m + 2) + mn(n + 2) + 2n(n + 2)

We factor to get,

= {(m + 2)}(m + 2 - 1) +n (n + 2) (m+ 2)

This implies that,

= {(m + 2)}(m + 1) +n (n + 2) (m+ 2)

We factor further to obtain,

= {(m + 2)}((m + 1) +n (n + 2))

or

= {(m + 2)}( {n}^{2} + 2n + m + 1)
