<span>For this example, the value presented would be considered a statistic. The value is a statistic as it represents a numerical measurement of a sample. If it were a parameter, it would need to represent a numerical measurement of a population.</span>
300/8 = 37.5
37.5 x 12 = 450
New temp. = 450 K

Answer:
endothermic
Explanation:
An endothermic is any process with an increase in the enthalpy H (or internal energy U) of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
Answer:
900.48925 Hz
979.9785 Hz
Explanation:
= Relative velocity of ambulance =
= Velocity of wall = 0
v = Velocity of sound in air = 343 m/s
From doppler effect we have
The frequency of sound is 900.48925 Hz
When the wall acts like a source
The frequency of sound is 979.9785 Hz
