A consulting company claims that if job seekers attend the company's career development course, their chance of obtaining a job is greatly increased. The company also claims if the job-seeker obtains a job, the course will increase their annual salary by $7,295.00. Kevin, a job-seeker, must decide whether to pay to attend the company's career development course. The cost of the course is $2,763.00, and the average salary in Kevin's desired profession is $61,207.11. Suppose Kevin's chance of getting a job over the next year is 76%. What should Kevin do if he wants to maximize his earnings over the next year?Kevin should not attend the career development course because the expected value of attending the career development course is greater than the expected value of not attending the career development course.Kevin should attend the career development course because the expected value of attending the career development course is less than the expected value of not attending the career development course.Kevin should not attend the career development course because the expected value of attending the career development course is less than the expected value of not attending the career development course.Kevin should attend the career development course because the expected value of attending the career development course is greater than the expected value of not attending the career development course.

Which statement best explains whether the table represents a linear or nonlinear function? Input (x) Output (y) 2 5 4 10 6 15 8 20 A It is a linear function because the input values are increasing. B It is a nonlinear function because the output values are increasing. C It is a linear function because there is a constant rate of change in both the input and output. D It is a nonlinear function because there is a constant rate of change in both the input and output.

Look at this function: x y −12 −8 −8 −6 −4 −4 0 −2 Mina said that the function is linear. Jenna said that the function is nonlinear. Which of the following explains who is correct? A Mina, because for every 2-unit increase in x, there is an increase in y by 4 B Mina, because for every 4-unit increase in x, there is an increase in y by 2 C Jenna, because the point (0, −2) does not lie on the straight line that contains the other points D Jenna, because the point (−12, −8) does not lie on the straight line that contains the other points

3. [09.01] A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent? (2 points) t = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground t = 1.5; it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground t = 3; it takes 3 seconds to reach the maximum height and 3 seconds to fall back to the ground t = 3; it takes 3 seconds to reach the maximum height and 6 seconds to fall back to the ground
