The following two-way table shows the data for the students of two different grades in a school: member of science club not member of science club total grade 7 20 2 22 grade 8 20 8 28 total 40 10 50 based on the relative row frequency, the students of which grade are more likely to be members of the science club? grade 7 grade 8 the students of both grades are equally likely to be members of the science club no conclusion can be drawn about the chances of a student being a member of the science club

grade 7

Step-by-step explanation:

Grade 7: 20/22 students in club

Grade 8: 20/28 students in club

Grade 7 has higher % of students in science club

Grade 7

Step-by-step explanation:

The relative row frequency of members of the Science Club is: Member of Science Club / Total

in Grade 7: 20/22 = 0.91.

And in Grade 8 is: 20/28 = 0.71.

Then, students of Grade 7 are more likely to be members of the science club.

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
