The following table shows some data from a study on substance use among 8th and 12th graders in a certain country. 8th Vaped Vaping-Free Totals X y 60,000 12th Z W 50,000 Total 100,080 110,000 (a) The table leads to a linear system of four equations in four unknowns. What is the system? (Enter your answers as a comma-separated list of equations.) Does it have a unique solution? O This system has no solution. O This system has infinitely many solutions. This system has one solution. ○ This system has a finite number of solutions. Perfect! What does this indicate about the missing data? ○ The given data is sufficient to obtain the missing data (x, y, z and w). The given data is insufficient to obtain the missing data (x, y, z and w). Well done! (b) Given that -80 more 12th graders vaped than 8th graders, find the missing data. (x, y, z, w) =
