We know that , the indicator variable is a dummy variable in regression analysis which is used to denote either presence ( by 1 ) or absence ( by 0 ) of a nominal variable that can be responsible for the change in output.

Number of indicator variables = (all levels in the original variable)-1

Here , the given categories as per the location are northeast, northwest, southeast, or southwest.

A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?
Drupady [299]

Answer:

16.56\ g

Step-by-step explanation:

we know that

The density is equal to the mass divided by the volume

Let

x-----> the mass of marble

y----> the volume of marble

z----> the density of marble

z=\frac{x}{y}

in this problem we have

y=6\ cm^{3}

z=2.76\ g/cm^{3}

substitute and solve for x

2.76=\frac{x}{6}

x=2.76*6=16.56\ g
