Write 5A^2 - 6A = 3I in the form AB = I and hence find A^-1 in the terms of A and I

Hello fellow student of Stroh, how goes it? Anyways, to solve this problem heres what you do. 5A^2-6A=3I 5/2A^2-2A=I A(5/2A-2I)=I A^-1 * A (5/2A-2I) = A^-1 * I 5/2A-2I=A^-1 So as weed need to find AB=I, we know that B=A^-1 (A^-1*A*B=A^-1*I) and the above found A^-1, just multiply that by A to get your proper form. A(5/2A-2I)=I A     B     =I

55% of graduates find a job in field, probability that 1 of 7 random graduate find a job

wot yu need tu du is: chans 1 student will NOT find a job=45% chans 7 students will NOT find a job=(0.45)^7 =0.0037366945 or 0.0037 thus chans 1 av 7 students will find job=1-0.0037 =0.996263 or 99.6%
