1st, let's calculate the side AB = c in applying the law of cosine:
AC² = BC²+AC² - 2AB.BC. cos87°)
c²= 10.1²+9.8²-2(10.1)(9.8)(cos(87)
c²=102.01 + 96.04 -196.96cos(87)
c² = 187.74 and c = 13.7
Having calculated the 3rd side, now we can apply Heron's formula for the area:
AREA = √p(p-a)(p-b)(p-c), where p is half the perimeter or p=(a+b+c)/2 =16.8
AREA = √16.8(16.8-10.1)(16.8-9.8)(16.8-13.7)
AREA = 49.42 OR 49.4 unit²
Answer:
Option D is the right answer
Explanation:
An Incident Commander's scope of authority is derived from existing laws, agency policies, procedures, and/or through a delegation of authority from the agency administrator or elected official.
Within his/her scope of authority, the Incident Commander establishes incident objectives, then determines strategies, resources, and ICS structure based on the incident objectives.
The incident commander is the person responsible for all aspects of an emergency response; including quickly developing incident objectives, managing all incident operations, application of resources as well as responsibility for all persons involved.
The role of incident commander may be assumed by senior or higher qualified officers upon their arrival or as the situation dictates. Even if subordinate positions are not assigned, the incident commander position will always be designated or assumed.

Answer:
B) The sample size must be greater than 30
Explanation:
According to the central limit theorem the sample size must be greater than 30 in sampling distributions to state that it is approximately normal.
Therefore, the sample size must be greater than 30 for the sampling distribution of the sample proportion of housing units in the large city that are rentals to be approximately normal.
