Machine set up is correct 60% of time & is incorrect 40% of time, 10 % of parts produced are defective when set up is correct, & 60 % would be defective if set up is incorrect. Find the probability that part is defective even though machine was set up correctly

an undamped mass spring system is with mass of 12kg and stiffness of 15N/mm,a)determine the natural frequency and the period of the free motion of the system b)determine the amplitude of displacement A and the phse shift for the initial conditions x0=2mm,v0=-1mm/s

why you argee? this statement. about univesity kids: the top 20 percent are great. they re smart and self directed and they'll anywhere. then there are the rest. they dont know much. I need to write some lines why i agree please give some ideas to start and how to end.

plug in 1 for n for the first term. plug in 2 for second term and so aon until the sixth term ex:(-3)n (-3)1=-3 (-3)2= -6 etc... :P

plug in the value for x and solve 3(2)-10 6-10 =-4 capish?

Draw graph of y= x^(1/2) to help you understand solution. Rotation about y-axis means that the radius of the solid (length being swung around the axis is the x-value). it helps to solve for x-value rather than try to substitute everything. x=y^2 where y>0 each disk or x-val...

Graph it if you don't understand my solution: Linear equations follow the format y=mx+b where m is the slope and b is the y-intercept. let y= fees and x=number of credits now calculate slope (change in y/change in x) m=(2600-2000)/(6-3)= 200 y=200x+b Plug in any point to f...

a) illogical nonidentity because 4 does not equal 5 b) testable statement. i don't know your definition of logical statement and can't be of much more help here 3) false obviously d) logical statement due to commutative prop of addition
