Manufacture of a certain component requires three different machining operations. Machining time for each operation has a normal
Nikolay [14]

Answer:

0.0359

Step-by-step explanation:

Data provided:

mean values of three independent times are 15, 30, and 20 minutes

the standard deviations are 2, 1, and 1.6 minutes

Now,

New Mean = 15 + 30 + 25 = 65

Variance = ( standard deviation )²

or

Variance = 2² + 1² + 1.6² = 7.56

therefore,

Standard deviation = √variance

or

Standard deviation =  2.75

Thus,

Z-value = \frac{\textup{60 - 65}}{\textup{2.75}}

or

Z-value = - 1.81

from the Z-table

the Probability of Z ≤ -1.81 = 0.0359

yan [13]

Answer:

sp with vat=9040

d=20%

vat=13%

mp=?

Step-by-step explanation:

sp with vat=9040

sp+vat%of sp=9040

sp(1+13/100)=9040

sp=9040/1.13=8000

  • mp=sp+d%ofmp
  • mp-d%ofmp=sp
  • mp(1-20/100)=8000
  • mp=8000/0.8=10000
