Explanation:

Step1: Understand the meaning of "at least"

"At least \(\frac{1}{2}\) of an inch" means \(\frac{1}{2}\) inch or more.

Step2: Count the number of Xs

Count the number of Xs at \(\frac{1}{2}\), \(\frac{3}{4}\), and \(1\).

• At \(\frac{1}{2}\): \(1\) X
• At \(\frac{3}{4}\): \(4\) Xs
• At \(1\): \(1\) X

Step3: Sum up the counts

\(1 + 4+1=6\)

Answer:

\(6\)
