Hide div after first two that do not contain checked radio buttons
<p><a href="http://jsfiddle.net/rockitdev/e755d/57/" rel="nofollow">JSFiddle</a></p>

<p>After the first two mini-cog divs, if the radio button contained within it is not checked I want it to hide the div but it's just hiding all divs after the first 2 (the 5th is checked so it should not be hidden in this example).</p>

<p><strong>jQuery :</strong></p>

<pre><code>$("div.mini-cog").slice(2).each(function () {

    // this is hiding Radio Button Question 5, but since its checked i want it to appear
    // $(this).find(':input').not(':checked').parent('div').hide();
});
</code></pre>

<p><strong>HTML :</strong></p>

<pre><code>&lt;form method="post" action=""&gt;
    &lt;div id="question-1" class="mini-cog"&gt;
         &lt;h4&gt;Radio Button Question 1&lt;/h4&gt;

        &lt;label for="radio-choice-1-a" class="checkbox inline"&gt;Choice 1
