Two components in the series have dependability of .
We need both two components to function in order to determine the engine's reliability. Since each component has dependability of , we must determine the likelihood that both components will function in order to determine the engine's reliability.
The possibility that a product, system, or service will function as intended for a predetermined amount of time, or that it will run faultlessly in a predetermined environment, is known as reliability.
By multiplying each of the reliability coefficients, we may calculate this probability:
P is equal to after being rounded to three decimal places.
The engine has a dependability rating of .
Hence,
Two components connected in series have dependability of .
Reliability and failure probability are complimentary, or.
In various cases, the distinctive qualities of a series arrangement will be demonstrated. is the resultant reliability of two components.
A component's reliability is assessed in light of the application for which it will be utilised. An operational profile gives a description of the situation. Software reliability can be calculated or measured.

#SPJ4
Answer:
14.3kg
Explanation:
Given parameters:
Quantity of heat = 149000J
Change in temperature = 5.23°C
specific heat of the ice = 2000J/kg°C
Unknown:
Mass of the ice in the bag = ?
Solution:
The heat capacity of a substance is given as:
H = m c Ф
H is the heat capacity
m is the mass
c is the specific heat
Ф is the temperature change;
since m is the unknown, we make it the subject of the expression;
m = H/ mФ
m = = 14.3kg
