Question 14 1 pts A numerical algorithm is used to solve the following system of equations: 3z1-221 1-42-3 The numerical results are x1 = 0.997 and x2 = 1.002. The absolute values of the residuals associated with this numerical solution are (to four decimal places with a leading zero before the decimal point): e1 e2 Question 11 0/1 pts Reorder the equations below so that the coeffcient matrix is diagonally dominant. 3a+9b-3c + d-20 4a - 3b+ 12c +2d- 10 4 4a+ b+2c 10d 8 12a + 6b + 4c-1d--5 Question 3 1 pts If a floating point number is stored in 32-bit single precision, there is 1 bit for the sign, 8 bits for the exponent, and 23 bits for the mantissa. What is the machine epsilon in single precision (Enter the mantissa to four decimal places and an integer for the exponent)? x 10
