In this problem, we will explore how deepening the pipeline affects performance in two ways: faster clock cycle and increased stalls due to data and control hazards. Assume that the original machine is a 5-stage pipeline with a 1 ns clock cycle. The second machine is a 12-stage pipeline with a 0.6 ns clock cycle. The 5-stage pipeline experiences a stall due to a data hazard every 5 instructions, whereas the 12-stage pipeline experiences 3 stalls every 8 instructions. In addition, branches constitute 20% of the instructions, and the misprediction rate for both machines is 5%. (a) What is the speedup of the 12-stage pipeline over the 5-stage pipeline, taking into account only data hazards

Harwood company uses a job-order costing system that applies overhead cost to jobs on the basis of machine-hours. the company's predetermined overhead rate of $2.50 per machine-hour was based on a cost formula that estimates $240,000 of total manufacturing overhead for an estimated activity level of 96,000 machine-hours. required: 1. assume that during the year the company works only 91,000 machine-hours and incurs the following costs in the manufacturing overhead and work in process accounts: compute the amount of overhead cost that would be applied to work in process for the year and make the entry in your t-accounts. 2a. compute the amount of underapplied or overapplied overhead for the year and show the balance in your manufacturing overhead t-account. 2b. prepare a journal entry to close the company's underapplied or overapplied overhead to cost of goods sold.

Sales at a fast-food restaurant average $6,000 per day. the restaurant decided to introduce an advertising campaign to increase daily sales. to determine the effectiveness of the advertising campaign, a sample of 49 days of sales were taken. they found that the average daily sales were $6,300 per day. from past history, the restaurant knew that its population standard deviation is about $1,000. if the level of significance is 0.01, have sales increased as a result of the advertising campaign? multiple choicea)fail to reject the null hypothesis.b)reject the null hypothesis and conclude the mean is higher than $6,000 per day.c)reject the null hypothesis and conclude the mean is lower than $6,000 per day.d)reject the null hypothesis and conclude that the mean is equal to $6,000 per day.expert answer
