Outline the design of a scheme that uses message retransmissions with IP multicast to overcome the problem of dropped messages. Your scheme should take the following points into account: i) There may be multiple senders. ii) Generally only a small proportion of messages are dropped. iii) Recipients may not necessarily send a message within any particular time limit. Assume that messages that are not dropped arrive in sender order.

The gomez company, a merchandising firm, has budgeted its activity for december according to the following information: • sales at $500,000, all for cash. • merchandise inventory on november 30 was $250,000. • the cash balance at december 1 was $20,000. • selling and administrative expenses are budgeted at $50,000 for december and are paid for in cash. • budgeted depreciation for december is $30,000. • the planned merchandise inventory on december 31 is $260,000. • the cost of goods sold represents 75% of the selling price. • all purchases are paid for in cash. the budgeted cash disbursements for december are:

Materials purchases (on credit). direct materials used in production. direct labor paid and assigned to work in process inventory. indirect labor paid and assigned to factory overhead. overhead costs applied to work in process inventory. actual overhead costs incurred, including indirect materials. (factory rent and utilities are paid in cash.) transfer of jobs 306 and 307 to finished goods inventory. cost of goods sold for job 306. revenue from the sale of job 306. assignment of any underapplied or overapplied overhead to the cost of goods sold account. (the amount is not material.) 2. prepare journal entries for the month of april to record the above transactions.

True or false: a fitted model with more predictors will necessarily have a lower training set error than a model with fewer predictors.
