A tank contains 420 litres of a solution, with 20 kilograms of salt in the solution. A solution with a concentration of $\frac{5}{7}$ kilograms per litre enters the tank at a rate of 7 litres per minute. The well-stirred solution flows out of the tank at the same rate. Determine the mathematical model that gives the function $y(t)$, the number of kilograms of salt in the tank after $t$ minutes.\ A. $\frac{dy}{dt} = \frac{5y}{7}$ and $y(0) = 420$ \ B. $\frac{dy}{dt} = 7 - (\frac{20}{420})(7t)$ and $y(0) = \frac{5}{7}$ \ C. $\frac{dy}{dt} = 20 - \frac{y}{420}$ and $y(0) = 5$ \ D. $\frac{dy}{dt} = 5 - \frac{y}{60}$ and $y(0) = 20$ \ E. $\frac{dy}{dt} = 7 - \frac{y}{420}$ and $y(0) = 20$

Question 1: A typical machine has a 32-bit IR and a total of 128 different instructions. Show the instruction format for such a machine if it has one memory address. How many memory locations can this machine access? Question 2: Assume a machine that has instructions of length 16 bits. An instruction has a 6-bit operation code and a 10-bit memory address. Assume that the machine has the following instructions: Load AC from memory, Store AC to memory, Add contents of memory to AC, and save it into AC. Assuming a memory that has 16-bit locations, A. Assign an operation code for each instruction. B. Write a program (sequence of instructions) that adds the contents of Memory location 151h to the contents of Memory location 150h and stores the result in location 152h. If the program starts at location 100h, show the contents of the locations that carry the program. C. Show the contents of IR, PC, AC, and Memory locations 150h, 151h, and 152h during execution (after each fetch cycle and each execute cycle). Initially, Location 150h has the value 2Bh and Location 151h has the value A1h. Question 3: For the machine described in question 2, assume a memory that has 8-bit locations and a data bus of 16 bits (two locations can be transferred to the CPU at a time). a) How many memory locations could the memory have? b) Repeat part (c) in question 2.

1) A dart game costs $5 to play. If the player hits the center, they win $30. If the player hits the closest ring to center, they win $10. If the player misses both areas, they win nothing. The probability the player hits the center is 0.2, but the probability the player misses both areas is 0.55. a) Fill in the following table (4.5 points). OUTCOME PAYOUT P(X = x) b) What is the expected value of this game (1.5 points)? c) What is the standard deviation of the game (1 point)? 2) As of 2023, 22% of social media users worldwide use TikTok. If 15 people are selected at random: a) What is the probability that the first 4 people selected use TikTok (1 point)? b) What is the probability that 8 use TikTok (1 point)? c) What is the probability that at most 7 of the randomly selected people use TikTok (1 point)?

Texts: Copy the included Node class into a file Node.py in your project. In your main function, allow the user to keep adding items to a linked list until they are finished (you may copy the main function from slide 41, where names are added until the user enters 'q'). After the user is done creating the linked list, pass the head to the following functions which you will create: 'length'. This function accepts the head of a linked list and returns the number of items in it. 'num_times'. This function accepts the head of a linked list and a target value. It should return the number of times the target value appears in the linked list. For your test code, you may simply hardcode a value for the target. class Node: """ Represents a singly-linked node """ def __init__(self, data, next=None): self.data = data self.next = next
