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).

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

answer: 0.26
