The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $830,000, and it would cost another $17,500 to install it. The machine falls into the MACRS 3-year class (the applicable MACRS depreciation rates are 33.33%, 44.45%, 14.81%, and 7.41%), and it would be sold after 3 years for $630,000. The machine would require an increase in net working capital (inventory) of $14,500. The sprayer would not change revenues, but it is expected to save the firm $457,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 40%. What is the Year-0 net cash flow? $ What are the net operating cash flows in Years 1, 2, and 3? Round your answers to the nearest dollar. Year 1 $ Year 2 $ Year 3 $ What is the additional Year-3 cash flow (i.e, the after-tax salvage and the return of working capital)? Round your answer to the nearest dollar. $ If the project's cost of capital is 11 %, what is the NPV of the project? Round your answer to the nearest dollar. $ Should the machine be purchased?

Unlike direct materials, the sum of all the direct labor variances is always equal to the flexible budget variance.

True

False

A negative direct labor efficiency variance is considered favorable.

True

False

For direct labor, if the efficiency and rate variances are both negative, then the flexible budget variance will be unfavorable.

The credit department of Lion’s Department Store in Anaheim, California, reported that 26% of their sales are cash, 27% are paid with a credit card, and 47% with a debit card. Twenty percent of the cash purchases, 86% of the credit card purchases, and 61% of the debit card purchases are for more than $50. Ms. Tina Stevens just purchased a new dress that cost $120. What is the probability that she paid cash? (Round your answer to 3 decimal places.)

Nike claims that the number of miles a jogger can get a on a pair of Nike’s running shoes is higher than 1000. Moreover, Nike also claims that their shoes outperform Adidas shoes by more than 15 miles. We have samples of 150 joggers using Nike shoes and 170 using Adidas shoes. The sample average of miles they got are 1015 for Nike and 995 for Adidas. The sample standard deviations are 100 for Nike and 50 for Adidas.

a.) At a 5% level of significance, is there statistical evidence showing that Nike shoes get more than 1000 miles?

b.) Obtain the p-value for the previous test. What does it mean?

c.) At a 5% level of significance, is there statistical evidence showing that Nike shoes outperform Adidas shoes?

d.) Obtain the p-value for the previous test. Interpret.

emergency physics question!

In recent years, public universities have experienced major budget cuts due to reduced funding from their state governments. These budget cuts usually occur at the most inopportune time—during the school year when contractual commitments with faculty and staff had been signed, programs had been planned, and students were enrolled and taking classes.

Required:

1. Should the administration be “fair” to all affected and institute across-the-board cuts whenever the state announces a reduction in funding?
2. If not across-the-board cutbacks in programs, then would you recommend more focused reductions, and if so, what priorities would you establish for bringing spending in line with revenues?
3. Since these usually are not one-time-only cutbacks, how would you manage continuous, long-term reductions in budgets extending over a period of years?
4. Should the decision-making process be top-down (centralized with top administrators) or bottom-up (participative)? Why?
5. How should issues such as protect-your-turf mentality, resistance to change, and consensus building be dealt with?

You need to write and run C programs (as processes on your Linux machine), and monitor their behavior. Consider the following problem: A program is to be written to print all numbers between 1 and 1000 (inclusive) that are not (evenly) divisible by either 2 or 3. This problem is to be solved using three processes (P0, P1, P2) and two one-integer buffers (B0 and B1) as follows:  P0 is to generate the integers from 1 to 1000, and place them in B0 one at a time. After placing 1000 in the buffer, P0 places the sentinel 0 in the buffer, and terminates.  P1 is to read successive integers from B0. If a value is not divisible by 2, the value is placed in B1. If the value is positive and divisible by 2, it is ignored. If the value is 0, 0 is placed in B1, and P1 terminates.  P2 is to read successive integers from B1. If a value is not divisible by 3, it is printed. If the value is positive and divisible by 3, it is ignored. If the value is 0, P2 terminates. Write a program to implement P0, P1, and P2 as separate processes and B0 and B1 as separate pieces of shared memory {each the size of just one integer}. Use semaphores to coordinate processing. Access to B0 should be independent of access to B1; for example, P0 could be writing into B0 while either P1 was writing into B1 or P2 was reading.

At 700 K acetaldehyde decomposes in the gas phase to methane and carbon monoxide. The reaction is:
CH3CHO(g)→CH4(g)+CO(g)
A sample of CH3CHO is heated to 700 K and the pressure is measured as 0.43 atm before any reaction takes place. The kinetics of the reaction are then followed by measurements of total pressure and these data are obtained:

Question:

Find total pressure after 1.39×10⁴ s .

************CODING IN C++ ONLY ********************

Instructions

Write a function, remove, that takes three parameters: an array of integers, the number of elements in the array, and an integer (say, removeItem).

The function should find and delete the first occurrence of removeItem in the array. (Note that after deleting the element, the number of elements in the array is reduced by 1.) Assume that the array is unsorted. Also, write a program to test the function.

Your program should prompt the user to enter 10 digits for the array. Display the starting array to the user and prompt them to select an integer to remove. After the selected integer has been removed, the updated list should be displayed to the user. If the value does not exist or the array is empty, output the following message: x is not in the list

GRADING CRITERIA

1)  Defined the remove function

2) Removing elements from the list

3) List does not contain integer to be removed
