Answer:
Social environment.
Explanation:
When businesses collect demographic information on where people live, what they buy, and how they spend their time, they are responding to the social environment. The social environment comprises of values, beliefs, practices, customs and behaviors of a group of people living together in a society and how their actions influence their surroundings or environment.
Demographics can be defined as the study and analysis of the characteristics of a population based on pre-defined factors such as education, race, income, sex or gender, and age.
Additionally, businesses gather, analyze and use demographic informations about people in the target market so as to have a competitive edge or advantage and to help build a strong relationship.
The application administrator should tighten measures on the external application used in the database backend especially when it comes to creating user IDs in order to prevent unauthorized users - any off-campus or even non-affiliated users to indiscriminately post links, especially malware and malicious ones. This can be done by selecting a viable verification method in order to only allow on-campus students to sign-up to the service.
Solution:
Given Information,
Heat input is ( 
) = 5.5 × 
Btu/h
Combustion efficiency of the boiler (
) = 0.7
Combustion efficiency after turn up (
) = 0.8
Operation Hour (t) = 5200h
Unit cost (c) = 
Calculate heat output from the boiler 
= x
= 5.5 x x 0.7
= 3.85 x Btu/h
Calculate the heat input to the boiler after the tune-up
= / 
= 3.85 x / 0.8
= 4.8125 x Btu/h
Calculate the saved energy after the tune-up
= -
= 5.5 x - 4.8125 x Btu/h
= 0.6875 x Btu/h
Calculate the annual energy saving ( 
)
= x t
= ( 0.6875 x Btu/h ) ( 5200 hr/yr)
= 3575 x Btu/h
Calculate the annual cost saving
Annual cost saving = 
x Unit cost
= 3575 x Btu/h x
= 82225
Answer:
The tax that must be added to the C corporation tax liability for the year before the S election = $49000*1/4=$12250
The rest of the three instalments of $12250 each will be paid with Lent Corporation's next three tax returns
Explanation:
FIFO Value/basis =$650000
LIFO value/basis =$510000
Difference =$140000
35% Tax =$140000*35% = $49000
The tax that must be added to the C corporation tax liability for the year before the S election = $49000*1/4=$12250
The rest of the three instalments of $12250 each will be paid with Lent Corporation's next three tax returns
