Question

Rick surveyed 50 students at his school to see how many have after-school jobs and how many are getting the new video game console that is coming out next month. From his data, 30% of the students are getting the new console. Also, of the 20 students who have after-school jobs, 45% are getting the new console. Using this information, complete the following table with the relative frequency of the columns. 0.30 0.70 1.00 0.20 0.80 0.45 0.55 Mathematics

Answer 1

I'm not sure about the "table" that the question mentions, but I'll try to help you break down the data

Answer 2

So, there are 50 students total in the survey.
30% of the total 50 plan to get the new console, so that makes 15 total students who plan to get the new console (50 * 0.3 = 15)
20 students have after-school jobs, which is 40% of the students surveyed (20/50 *100%)
And of these 20 students, 45% (9 students) plan to get the new console.
That also means that 9 of the 15 students who plan to get the new console have afternoon jobs. So, we can compute that 60% (9/15 *100%) of the students planning to get the console also have afterschool jobs.

Answer 3

By contrast, you can also say that 55% of students do *not* have afterschool jobs (100%-45%)
Similarly, 70% of the students do *not* plan to get the new console
And, 40% of students who plan to get the new console do *not* have afterschool jobs

Answer 4

You could also say that 9/50 students have a job *and* plan to get the new console, which would be 18% of the total students surveyed

Answer 5

So that covers what I assume the entries are supposed to be for 0.3, 0.7, 0.45, 0.55. And then 1.0 would just be all 50 students. I'm not sure what 0.2 and 0.8 could be referring to, though...
