Aresearch company performed a study of machiavellian traits in accountants. machiavellian describes negative character traits that include manipulation, cunning, duplicity, deception, and bad faith. a questionnaire was administered to a random sample of 900 acccounting alumni of a large university; however, due to nonresponse and incomplete answers, only 225 questionnaires could be analyzed. several variables were measured, including age, gender, level of education, income, job satisfaction score, and machiavellian ("mach") rating score. the research findings suggest that machiavellian behavior is not required to achieve success in the accounting profession. complete parts a through c below. a. what is the population of interest to the researcher?

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
