+ The work shows the first steps for writing a partial fraction which equations can be used in a system of equations
decomposition
to solve for the unknowns. Check all that apply.
4x3-5 AX + B CX + D
(2x2 + 1)2 (2x2 + 1)(2x2 + 1)2
O A=0
4x3 - 5 = (AX + B)(2x2 + 1) + (x+D
OB=0
4x3-5 = 2 AX3+ Ax + 28x2 + B + Cx +D
OD=-5
O A+C=0
2A + 2B = 4
Done

Asample of 200 rom computer chips was selected on each of 30 consecutive days, and the number of nonconforming chips on each day was as follows: the data has been given so that it can be copied into r as a vector. non. conforming = c(10, 15, 21, 19, 34, 16, 5, 24, 8, 21, 32, 14, 14, 19, 18, 20, 12, 23, 10, 19, 20, 18, 13, 26, 33, 14, 12, 21, 12, 27) #construct a p chart by using the following code. you will need to enter your values for pbar, lcl and ucl. pbar = lcl = ucl = plot(non. conforming/200, ylim = c(0,.5)) abline(h = pbar, lty = 2) abline(h = lcl, lty = 3) abline(h = ucl, lty = 3)
