densk [106]

Answer:

Minutes can provide us the continuous data as we can have the values between the two minutes, in fraction. So if we consider minutes there will be a complete continuous data for the analysis. However the number of cars, trucks, pedestrians, bicyclists, food trucks etc will be in integers as they can not be described in terms of fractions. So for continuous data option (E) is correct.

The number of minutes for a car to get from the intersection to the administration building.

Alla [95]

Answer:

7213.7kg/m³

Explanation:

Given parameters:

Volume of the metal chunk  = 0.131m³

Mass of the metal chunk  = 945kg

Unknown:

Density of the metal chunk  = ?

Solution :

To solve this problem, density is the mass per unit volume. It is mathematically expressed as;

  Density  = \frac{mass}{volume}  

 So;

 Density  = \frac{945}{0.131}   = 7213.7kg/m³

Sloan [31]

Answer:

77.88 lbm/ft³

Explanation:

Given,

Specific gravity, SG = 1.25

Density of water, ρ = 62.30 lbm/ft³

density of the fluid =

   = S.G x ρ_{water}

   = 62.30 x 1.25

   = 77.88 lbm/ft³

Density of the fluid is equal to 77.88 lbm/ft³
