A farm consists of 220 acres of land.  The farmer plans to plant corn (x) and oats (y).  Profit per acre in corn is $40 and in oats is $25.  The number of labor hours is 300; where each acre of corn requires 2 hours, and oats require 1 hour per acre.  Determine the number of acres of corn and of oats that should be planted to maximize profit. Graph the feasible solution and find the corner points.  1.  How many corner points exist for the feasible solution?  2.  One corner point does NOT lie on the x or y axis, what is the y-value of this corner point?  3.  What is the maximum profit?    Do NOT put a comma nor $ sign in your answer for the thousands mark (i.e., use 2000 and NOT $2,000.00).  You may round your answer to the nearest dollar. (When you finish, make sure to show your work to the camera for few seconds, submit your work after you finish the exam. The submitted copy must match what you showed to the camera.  Answers without the chart will not be counted)

Refer to Figure 7.  For each of the following bones, identify whether they are LEFT or RIGHT:  BONE A: BONE C: BONE E: BONE G:

Refer to Figure 13.  Name a muscle that performs the following actions AND include the Number that labels it on the figure.  1. FLEXES the FINGERS. Muscle Name & Number: 2. EXTENDS the WRIST. Muscle Name & Number:

Refer to Figure 10.  Name a muscle that performs the following actions AND include the Letter that labels it on the figure.  1. FLEXES the ELBOW joint. Muscle Name & Letter: 2. ADDUCTS the arm at the SHOULDER joint. Muscle Name & Letter: 3. FLEXS the WRIST joint. Muscle Name & Letter:

Refer to Station/Figure 2.  Examples A and B are drawings of bones from two different pelvises – one of these is ‘male’ and one is ‘female.’ Compare these drawings and use the information from your comparison to PREDICT whether the model pelvis in C is male or female.  A complete answer will identify the sex for each example, A & B, give TWO anatomic reasons how you know this is true, AND a prediction about whether C is male or female based on your reasons. 

Refer to Figure 9. For each of the following bone pairs, name the TWO BONES and the SPECIFIC TYPE of JOINT between them. Name of Bones 2 & 3: , specific type of joint: Name of Bones 9 & 11: , specific type of joint: Name of Bones 10 & 12: , specific type of joint:

Mark True or False for each statement below. 1. TCP flow control ensures that the sender does not overwhelm the receiver by monitoring the size of the receiver’s buffer. 2. The sliding window protocol allows TCP to transmit data even when the window size is zero. 3. With every acknowledgment message, the receiver advertises its current receive window size. 4. The receive window size decreases as the application consumes data from the buffer. 5. TCP flow control relies solely on the sender to determine how much data can be transmitted at a time.

Mark True or False for each statement below. 1. The Internet Protocol (IP) was created as part of the OSI (Open Systems Interconnection) model to ensure a strictly layered approach to networking. 2. The OSI model includes seven layers, while the IP model condenses these into four layers: Access, Network, Transport, and Application. 3. Each Internet packet contains information such as source and destination IP addresses, the protocol being used, and error detection data. 4. In the process of packet delivery, packets always follow the same route through the network to ensure reliability. 5. IPv4 addresses are 32-bit numeric addresses divided into four bytes.

Mark True or False for each statement below. The scheduler is a part of the operating system responsible for selecting which process runs next, balancing the needs of processes to prevent starvation. The scheduler sets an alarm to manage process execution time, ensuring that a process runs only for its allocated quantum of time. A process in the “Ready” state is runnable but not currently executing on the CPU. A context switch occurs only due to voluntary CPU yield operations, such as a process going to sleep. A context switch involves saving the state of the currently running process so it can resume later.  

Mark True or False for each statement below. 1. A file system helps to locate free storage space and allows multiple processes to access stored information concurrently. 2. File types can only be identified by their file extensions, like .docx or .jpg. 3. In UNIX systems, a soft (symbolic) link allows linking across different file systems, unlike a hard link. 4. A directory is a special file type that stores part of the File Control Block (FCB) information about other files. 5. The link count of a file in UNIX systems increases every time the file is opened to prevent deletion during operation.
