did you ask your teacher for help...... or something.........

Answer 10

Seriously?! You must SHOW YOUR WORK! No one knows how to help you until you DO something. TAGGING everyone falls under the definition of SPAM. Don't do it. It takes a little patience, sometimes.

C = Number of Children in the Study
A = Number of NonChildren in the Study.

\(C + A \ge 40\)

\(C \le 30\)

If there is more to be done, here, it is not clear from your problem statement. Show your work and someone is likely to help you finish up.
