A furniture factory has 2230 machine hours available each week in the cutting department, 1470 hours in the assembly department, and 2960 in the finishing department. Manufacturing a chair requires 0.3 hours of cutting, 0.5 hours of assembly, and 0.6 hours of finishing. A cabinet requires 0.8 hours of cutting, 0.3 hours of assembly, and 0.1 hours of finishing. A buffet requires 0.2 hours of cutting, 0.1 hours of assembly, and 0.9 hours of finishing. How many chairs, cabinets, and buffets should be produced in order to use all the available production capacity?
Please help and provide step by step so I can learn how to do this! Thank you :)

Please show all steps. Consider the following data pertaining to the three warehouses operated by a company:
| Warehouse # |
Std. deviation of lead time demand |
| 1 | 845 |
| 2 | 410 |
| 3 | 225 |
The company considers consolidating any two of its warehouses (i.e., risk pooling). Based on
the information provided above and given that lead time demands between any two
warehouses are correlated at -0.3 (i.e.,ρ12=ρ23=ρ13= -0.3). In which case will the reduction
in safety stocks resulting from warehouse centralization likely be the greatest if we want to
achieve a 97% service level? (Please provide detailed calculation processes. Typed also)

1. A 100.0-mL sample of 0.500 M sodium hydroxide is titrated with 0.100 M nitric acid. Calculate the pH after 400.0 mL of acid has been added.
2. A 1.0-L buffer solution contains 0.100 mol HCN and 0.100 mol LiCN. The value of Ka for HCN is 4.9 x 10-10. Because the initial amounts of acid and conjugate base are equal, the pH of the buffer is equal to pKa = -log (4.9 x 10-10) = 9.31. Calculate the new pH after the addition of 0.010 mol of HNO3 to the buffer. Ignore any change of volume brought about by this addition.
3. Calculate the pH of a 1.0-L solution that is 0.50 M in NH3 and 0.20 M in NH4Cl after the addition of 30 mL of 1.0 M HNO3 to the buffer. pKb = 4.75.

An Izod impact test was performed on 20 specimens of PVC pipe. The ASTM standard for this material requires that Izod impact strength must be greater than 1.0 ft-lb/in. The sample average and standard deviation obtained were x = 1.121 and s = 0.328, respectively. (a) Test H0: µ = 1.0 versus H1: µ 1.0 using α = 0.01 and draw conclusions. (b) Use the P-value approach to confirm your inference (c) Construct the 99% lower confidence bound on the mean and use it to test the hypothesis. (d) Suppose that the mean strength is as high as 1.1 ft-lb/in, the engineer would like to detect this difference with probability at least 0.90. Was the sample size n = 20 used in part (a) adequate? Use the sample standard deviation s as an estimate of σ in reaching your decision. Estimate what sample size is needed to detect this difference.

One mole of Neon at T=298K and P=10.0 bar expands to final pressure of 1.0 bar. Calculate the final temperature, q, w, change in energy, enthalpy, eand entropy when the expansion is carried our according to the following scenarios:
A. They system is held in a heat bath that maintains constant temperature and the expansion is carried out very slowly and carefully, with the external pressure being gradually reduced from 10 bar to 1 bar.
B. The system is held in a constant-temperature bath, but the external pressure is reduced suddenly from 10 bar to 1.0 bar at the very begining and kept at 1.0 bar thereafter.
C. The system is thermally insulated and the external pressure is reduced slowly and carefully.
D. The system is thermally insulated, and expand into an evacuated container having 10 times the volume of the flask. No external pressure opposes the expansion.
