<p>I can not figure out how to do </p>
<p>PAGE 843 NUMBER 18</p>
<p>in the BLUE BOOK. Also, an explanation is not on CC yet.</p>
<p>Well since 1351 is the median it looks like this.</p>
<p>__ __ 1351 __ __</p>
<p>Plug in the numbers in order u get…</p>
<p>__ __ 1351 1459 1552</p>
<p>However, note that 1238 has to be in the first blank for the new number to be at maximum</p>
<p>1238 __ 1351 1459 1552</p>
<p>Now since it says that now two numbers are the same and that 1351 is the medium than it has to be a number great than 1238, but less than 1351.</p>
<p>So it’s 1350.</p>
<p>Thanks.</p>
<p>Can some explain</p>
<p>PAGE 860 NUMBER 19</p>
<p>Please!</p>
<p>ok so a function f(x) is 2x-1. 1/2f(squareroot of t)=4</p>
<p>so just plug in answer choices</p>
<p>try 81/4= t</p>
<p>so squareroot of 81/4</p>
<p>is 9/2</p>
<p>9/2 times 2 -1=8 times 1/2 =4. answer is e.</p>
