Amelia, luis, shauna, and clarence used different approaches to solve the inequality 7.2b + 6.5 > 4.8b – 8.1. amelia started by subtracting 7.2b from both sides to get 6.5 > –2.4b – 8.1. luis started by subtracting 4.8b from both sides to get 2.4b + 6.5 < – 8.1. shauna started by subtracting 6.5 from both sides to get 7.2b > 4.8b – 14.6. clarence started by adding 8.1 to both sides to get 7.2b + 14.6 > 4.8b. which student’s first step was incorrect, and why? amelia’s, because the variable term must be isolated on the left side luis’s, because he flipped the inequality sign when he subtracted shauna’s, because she did not apply the subtraction property of equality properly clarence’s, because the terms he added together were not like terms

The resumâ´es of two male applicants for a college teaching position in chemistry are placed in the same file as the resumâ´es of two female applicants. two positions become available, and the first, at the rank of assistant professor, is filled by selecting one of the four applicants at random. the second position, at the rank of instructor, is then filled by selecting at random one of the remaining three applicants. using the notation m2f1, for example, to denote the simple event that the first position is filled by the second male applicant and the second position is then filled by the first female applicant, (a) list the elements of a sample space s; (b) list the elements of s corresponding to event a that the position of assistant professor is filled by a male applicant; (c) list the elements of s corresponding to event b that exactly one of the two positions is filled by a male applicant; (d) list the elements of s corresponding to event c that neither position is filled by a male applicant; (e) list the elements of s corresponding to the event a â© b; (f) list the elements of s corresponding to the event a âş c; (g) construct a venn diagram to illustrate the intersections and unions of the events a, b, and c.
