Answer:
hello your question is incomplete attached below is the complete question
A) overall mean = 5.535, standard deviation ≈ 0.3239
B ) upper limit = 5.85, lower limit = 5.0
C) Not all the samples meet the contract specifications
D) fluctuation ( unstable Asphalt content )
Explanation:
B) The daily average asphalt content has to obtained in order to determine the upper and lower control limits using an average asphalt content of 5.5% +/- 0.5% everyday
The upper limit : 14 may = ( 5.8 + 5.1 ) / 2 = 5.85
The lower limit : 16 may = ( 5.2 + 4.8 ) / 2 = 5.0
attached below is the required plot
C ) Not all the samples meet the contract specifications and the samples that do not meet up are samples from :
15 may and 16 may . this is because their Asphalt contents are 6.2 and 4.8 respectively and sample number 18 and 20
D ) what can be observed is that the ASPHALT content fluctuates between the dates while the contract specification is fixed
Answer:
1123.6 pounds/ square inch.
Explanation:
Fluid pressure is the ratio of force or weight applied by the fluid per unit area.
i.e Fluid pressure =
The maximum load of the jack is obtained at its maximum capacity = 5000 pounds
Area of the large piston on the jack = 4.45 square inches
Thus,
Fluid pressure =
= 1123.5955
Fluid pressure = 1123.6 pounds/ square inch
Thu, the fluid pressure in the jack at maximum load is 1123.6 pounds/ square inch.
