A weak entity has a primary key that is partially or entirely generated from the relationship's parent entity.
An entity type should contain a key attribute that uniquely identifies each entity in the entity set, although certain entity types do not have a key attribute. These are known as Weak Entities.
Entity sets with insufficient properties to generate a primary key are referred to as weak entity sets, whereas entity sets with a primary key are referred to as strong entity sets. Because the weak entities lack a primary key, they cannot be recognized on their own and must rely on another entity (known as owner entity).
Hence, the correct option is weak entity.

Answer:
n= 6.11 years
Explanation:
Giving the following information:
Present value= $40,000
Future value= $20,000
Decrease rate= 0.12
<u>To calculate the number of years for the car to reach a value of $20,000; we need to use the following formula:</u>
n= ln(FV/PV) / ln(1+i)
n= ln(20,000/40,000) / ln(1.12)
n= 6.11 years
Answer: Material Efficiency
Explanation: Material Efficiency is concerned with the use of physical processes that uses less material to produce higher outputs using recycled materials thereby reducing wastes.
Material efficiency uses the strategy of re-manufacturing and modular manufacturing, reuse and recycling of product components, using less material in product designs and redesigning manufacturing processes to use less energy, less water and less raw materials.
Material efficiency help not only in reducing manufacturing costs but also in reducing wastes and associated costs.
