Double integrals are part of the fundamental concepts of Differential and Integral Calculus when we are interested in working with spatial notions of volumes or even surface areas. Based on this concept, judge the following information: I. To calculate a double integral in a rectangular region, we proceed with the use of dodecahedrons to approximate the volume of a surface. II. The gradient vector is used to calculate iterated integrals. III. The surface volume is approximated by the Riemann sum limit for functions of two variables. What is stated in:
Exercise 3 (15 points): Demonstrate the following properties, justifying: 1) If A, B and C are matrices of format m × n, then A + (B + C) = (A + B) + C. 2) If A is a matrix of format m × n and r, s are scalars, then (r + s)A = rA + sA.

Find an equation of the plane α if it passes through the point M (1,2,1) and is parallel to the plane β with equation 4x - y + z + 10 = 0.
A manufacturer of custom drinking mugs has a fixed setup cost of $1,000 per order plus a variable cost of $1.50 per mug. How many mugs were produced when the total cost was $2, 800?
The MSC was curious to see whether they could say that the mean number of visits per student after COVID is more than during COVID. We randomly took a sample of 64 students that visited the MSC during COVID and the mean number of visits was 2.8 with a standard deviation of 1.05. After COVID we took a random sample of 64 students that visited the MSC and found the mean number of visits per student was 3.2 with a standard deviation of 1.12. Run a hypothesis test at a significance level of 0.10 on the claim that the mean number of visits per student after COVID is greater than during COVID. Answer: 1. Null and Alternative Hypothesis 2. Test Statistic 3. P-Value - just state the p-value 4. Decision 5. Conclusion

ABC Corp. has just paid a dividend of $0.45. ABC has an annual required return of 11.68%. Attempt 1/5 for 10 pts. Part 1 If dividends are annual and expected to be constant, what is the value of the stock? 3.85 Correct ✓ Attempt 1/5 for 10 pts. Part 2 What is ABC's dividend yield? 11.88% Correct ✓ Attempt 1/5 for 10 pts. Part 3 From now on, assume that the dividend of $0.45 was a quarterly dividend. What is the quarterly discount rate? 2.7732% Correct ✓ Attempt 2/5 for 9 pts. Part 4 What is the value if dividends are constant and quarterly? 16.2 Correct ✓ Attempt 1/5 for 10 pts. Part 5 We now think that dividends will grow by 0.5% from quarter to quarter. The firm just paid the quarterly dividend of $0.45. What is the value of the stock? 19.88 Correct ✓ Attempt 2/5 for 9 pts. Part 6 A different analyst thinks that ABC's dividends will grow by 5% for the next 4 quarters, and then grow by 0.5% thereafter. What is the value of the stock?
Intro You bought a 10-year zero-coupon bond with a face value of $1,000 and a yield to maturity of 3.1% (EAR). You keep the bond for 5 years before selling it. Attempt 1/5 for 10 pts. Part 1 What was the price of the bond when you bought it? Part 2 What is the rate of return (HPR) if the yield to maturity is 4.9% when you sell the bond? Part 3 What is the rate of return (HPR) if the yield to maturity is 1.9% when you sell the bond?
Airline passengers arrive randomly and independently at the passenger-screening facility at a major international airport. The mean arrival rate is 10 passengers per minute, and passenger arrivals follow a Poisson distribution. (Round your answers to six decimal places.) solve and Compute the probability that three or fewer passengers arrive in a one-minute period. solve and Compute the probability of no arrivals in a 21-second period. solve and Compute the probability of at least one arrival in a 21-second period.
