The ages and grades of some of the 19 girls on a club soccer team are shown in the table.

Which two-way frequency table correctly shows the marginal frequencies?

C.

Step-by-step explanation:

Table A and Table D add up to a total of 21 girls. The question says there are 19 girls, so those two are eliminated. Table B's data doesn't even add properly so that is eliminated too. This leaves Table C.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
