SOLVE USING WHILE. A perfect number is a positive integer that is equal to the sum of its positive divisors except the number itself. The first two perfect numbers are 6 and 28 since 1+2+3=6 and 1+2+ 4+7+14=28. Write a matlab computer program that finds the first n perfect number (the user must input the value of n) and show them in a vector

Consider the following two-server one-queue system from time = 0 to time = 20 min. If both servers are available when a customer arrives, the customer will choose server1. Customers waiting in the queue enter service whenever any one of the two servers becomes available (first come, first serve). Arrivals and service times are: • Customer #1 arrives at t = 0 and requires 2 minutes of service time • Customer #2 arrives at t = 1 and requires 5 minutes of service time • Customer #3 arrives at t = 3 and requires 3 minute of service time • Customer #4 arrives at t = 12 and requires 4 minute of service time Solve for system throughput (X) (# of customers served per unit time during the simulation time), total busy time for server 1(B1), total busy time for server 2(B2), mean service time for server 1(Ts1), mean service time for server 2(Ts2), server 1 utilization (U1), server 2 utilization (U2), average delay in the queue (D), average number of customers in the queue (Q), and average number of customers in the system (L). Also, draw the graph of time vs number of customers in the system. Show your work to receive full credit.

The following transactions and adjusting entries were completed by Legacy Furniture Co. during a three-year period. All are related to the use of delivery equipment. The double-declining-balance method of depreciation is used.
| Year 1 | |
| Jan. 4 | Purchased a used delivery truck for $27,680, paying cash. |
| Nov. 2 | Paid garage $725 for miscellaneous repairs to the truck. |
| Dec. 31 | Recorded depreciation on the truck for the year. The estimated useful life of the truck is four years, with a residual value of $4,900 for the truck. |
| Year 2 | |
| Jan. 6 | Purchased a new truck for $49,850, paying cash. |
| Apr. 1 | Sold the used truck purchased on Jan. 4 of Year 1 for $15,050. (Record depreciation to date in Year 2 for the truck.) |
| June 11 | Paid garage $450 for miscellaneous repairs to the truck. |
| Dec. 31 | Recorded depreciation for the new truck. It has an estimated residual value of $9,185 and an estimated life of five years. |
| Year 3 | |
| July 1 | Purchased a new truck for $53,640, paying cash. |
| Oct. 2 | Sold the truck purchased January 6, Year 2, for $17,607. (Record depreciation to date for Year 3 for the truck.) |
| Dec. 31 | Recorded depreciation on the remaining truck purchased on July 1. It has an estimated residual value of $12,345 and an estimated useful life of eight years. |

| b. |
1/2 the previous |
|
| c. |
remain the same |
|
| d. |
2 times larger than the previous |

| e. |
4 times larger than the previous |
2. One form of Newton’s 2nd Law is written F = ma
If the mass is three times larger than before and the force is twice as large, the value of the new acceleration compared to its previous value will be

3.In a fictional alternate universe assume that Newton’s Second Law was a = m/F where a, m and F mean the same thing as they do in your current universe. Give a short answer to the following:
Explain what would happen to the value of a measured acceleration
in the alternate universe if the mass were suddenly increased while
the force stayed the same.
Explain what would happen to the value of a measured acceleration in the alternate universe if the mass stayed the same while the force suddenly decreased.

Many students accumulate debt by the time they graduate from college. Shown in the following table is the percentage of graduates with debt and the average amount of debt for these graduates at four universities and four liberal arts colleges. University % with Debt Amount($) College % with Debt Amount($) 1 72 32,970 1 83 28,754 2 68 32,110 2 94 29,000 3 58 11,228 3 56 10,201 4 64 11,853 4 49 11,015 a. If you randomly choose a graduate of College 2, what is the probability that this individual graduated with debt (to 2 decimals)? b. If you randomly choose one of these eight institutions for a follow-up study on student loans, what is the probability that you will choose an institution with more than 80% of its graduates having debt (to 3 decimals)? c. If you randomly choose one of these eight institutions for a follow-up study on student loans, what is the probability that you will choose an institution whose graduates with debts have an average debt of more than $ 20,000 (to 3 decimals)? d. What is the probability that a graduate of University 1 does not have debt (to 2 decimals)? e. For graduates of University 1 with debt, the average amount of debt is $ 32,970. Considering all graduates from University 1, what is the average debt per graduate? Round to nearest dollar.

Part 1:
Consider the following perpetual system merchandising transactions
of Belton Company. Use a separate account for each receivable and
payable; for example, record the sale on June 1 in Accounts
Receivable—Avery & Wiest.
June 1 Sold merchandise to Avery & Wiest for $9,850; terms 2/5,
n/15, FOB destination (cost of sales $7,000).
2 Purchased $5,250
of merchandise from Angolac Suppliers; terms 2/10, n/20, FOB
shipping point.
4 Purchased
merchandise inventory from Bastille Sales for $12,100; terms 3/15,
n/45, FOB Bastille Sales.
5 Sold merchandise
to Gelgar for $11,700; terms 1/5, n/15, FOB destination (cost of
sales $8,050).
6 Collected the
amount owing from Avery & Wiest regarding the June 1
sale.
12 Paid Angolac Suppliers for the June 2
purchase.
20 Collected the amount owing
from Gelgar regarding the June 5 sale.
