Researchers at the terry college of business at the university of georgia sampled 344 business students and asked them this question: “over the course of your lifetime, what is the maximum number of years you expect to work for any one employer? ” the sample resulted in ¯x = 19.1 years. assume that the sample of students was randomly selected from the 6000 undergraduate students at the terry college and that σ = 6 years. a. describe the sampling distribution of ¯x. b. if the mean for the 6000 undergraduate students is µ = 18.5 years, find p(x¯ > 19.1).c. if the mean for the 6000 undergraduate students is µ = 19.5 years, find p(x¯ > 19.1).

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
