Random variable
Explanation:
A function that assigns a numerical value to each outcome of an experiment is described as a random variable. Random variables helps to determine the outcome of a random event.
- Example of a random event is tossing of die, casting of a coin.
- Random variables ascribe numerical values to the outcome of an experiment.
- They are often used in probability to determine the extent of the certainty of an experimental procedure.

Answer:
3.7kg
Explanation:
The following data were obtained from the question:
Volume = 3.7L
Mass =?
Next, we shall convert 3.7L to m³.
This is illustrated below:
1000L = 1m³
Therefore, 3.7L = 3.7/1000 = 0.0037m³
Now, we can obtain the mass of the water as shown below:
Density of water = 1000kg/m³
Volume of water = 0.0037m³
Mass of water =..?
Density = Mass /volume
1000kg/m³ = Mass /0.0037m³
Cross multiply
Mass = 1000Kg/m³ × 0.0037m³
Mass = 3.7Kg
Therefore, the mass of the water is 3.7Kg.
Answer:
1/3 times.
Explanation:
Let V₀ be the peak voltage .
IR ( rms ) = ( V₀ / √2 R )
R is value of resistance
IC = ( V₀ ωC / √2 )
( 1 / ωC is reactance of capacitance in ac circuit )

= 
When frequency is tripled angular frequency will also be tripled
hence the ratio
becomes 1/3 times.
The answer to the question being asked on what do you called when the movement of the bones around a fixed angle without lateral displacement is ROTATION. Rotation movement allows the bone to move in a single long axis without being displaced.
