The answer is the second one: medulla.

Explanation:

  • Cerebellum: This part of the brain is primarily responsible for coordinating voluntary movements, balance, and posture. Damage to the cerebellum would likely result in issues with movement and coordination, but not directly with breathing or heart function.

  • Medulla: The medulla oblongata is a critical part of the brainstem that controls autonomic functions such as breathing, heart rate, and blood pressure. Damage to the medulla can result in the inability to breathe independently and the need for life support to maintain heart function, which aligns with Ian's condition.

  • Hypothalamus: This part of the brain is involved in regulating various autonomic functions, including temperature regulation, hunger, and thirst, but it is not directly responsible for controlling breathing or heart rate.

  • Midbrain: The midbrain is involved in functions such as vision, hearing, motor control, sleep/wake cycles, and arousal. While it plays a role in the overall function of the brainstem, it is not primarily responsible for autonomic functions like breathing and heart rate.

In summary, the medulla is the part of the brain most likely damaged in Ian's case, given his inability to breathe and maintain heart function without assistance.

Adames Corporation has two manufacturing departments-Cutting and Forming. The company used the following information at the beginning of the year to calculate predetermined overhead rates: - Estimated total direct labor-hours (DLHs): Cutting 6,000, Forming 23,000 - Estimated total machine-hours (MHs): Cutting 13,500, Forming 2,800 - Estimated total manufacturing overhead cost (fixed and variable): Cutting 732,000, Forming 247,000 During the most recent month, Adames started and completed one job. There were no beginning inventories. Information concerning the completed job is as follows: - Direct materials: Cutting 82,600, Forming 12,300 - Direct labor cost: Cutting 11,600, Forming 31,000 - Actual machine-hours: Cutting 1,700, Forming 140 - Actual direct labor-hours: Cutting 480, Forming 1,500 Assume that the company uses separate departmental predetermined overhead rates with the Cutting Dept using machine-hours as the allocation base and the Forming Dept using direct labor-hours. 1. Calculate the predetermined overhead rates for the Cutting and Forming departments separately (round to the nearest cent). 2. Using the departmental rates, calculate the total manufacturing overhead that would be applied to the job. 3. Calculate the cost per unit for the job if the job included 1,250 units (round to the nearest cent). 4. If the company had instead used one plantwide overhead rate, would you expect the job cost to be more or less accurate than what you calculated above?
