devlian [24]
<h2>It's <u>1849</u></h2>

I'll explain how I found it without actual multiplication,

{40}^{2}  = 1600 \\  {3}^{2}  = 9 \\ 2 \times 40 \times 3 = 240 \\

So,

{43}^{2}  = 1600 + 240 + 9 \\  = 1849

Hope this will help....

Number of emails received in one account every day from the day it was created until it was canceled:
3241004551 [841]
The answer is B. Complete information.

A sample means only part of the whole. From the day the email was created till it was cancelled is the whole population. Consider that no mails will no longer go in because it is closed so no more additional information or data will enter that category. So it would be considered as complete. If the situation were to ask from one point to another before it was cancelled it would be considered as a sample.

30 POINTS!!! PLEASE HURRY!!Which of the following graphs correctly represents x &gt; -1/2
miss Akunina [59]
<h3>Answer: Second graph</h3>

Why? Because we draw a dashed line through x = -1/2 = -0.5 on the horizontal number line (aka x axis). Then we shade to the right of this dashed line. The shaded region represents all points that make the inequality true. For example, the point (0,0) is in the shaded region. It has an x coordinate of x = 0 which is larger than -1/2

Side note: the dashed line says "points on this boundary do not count as solutions". So any point with an x coordinate of -1/2 does not count.
