Question

A survey was conducted with high school students in each grade to see how many prefer math or English. Some of the data are shown below.

A 6-column table has 3 rows. The first column has entries Math, English, total. The second column is labeled 9 with entries blank, 40, 63. The third column is labeled 10 with entries 18, blank, 26. The fourth column is labeled 11 with entries blank, 15, 29. The fifth column is labeled 12 with entries blank, 32, 67. The sixth column is labeled Total with entries 90, 95, 185.

Which statements are true? Check all that apply.

Twenty-three ninth graders and fifteen eleventh graders prefer math.
Fourteen eleventh graders prefer math and eight tenth graders prefer English.
Thirty-five twelfth graders prefer math and nine tenth graders prefer English.
Twenty-three ninth graders and thirty-five twelfth graders prefer math.
Eighteen tenth graders prefer English and fourteen eleventh graders prefer math.

Answer 1

Fill in missing entries by subtracting:
- 9th math = 63 − 40 = 23
- 10th English = 26 − 18 = 8
- 11th math = 29 − 15 = 14
- 12th math = 67 − 32 = 35

So the true statements are:
- "Fourteen eleventh graders prefer math and eight tenth graders prefer English."
- "Twenty-three ninth graders and thirty-five twelfth graders prefer math."
