Thirty adults were asked how many pets they have had over their lifetime.

The statement that is most likely true is that the median is in the 6-10 interval and the mean is in the 6-10

There were a total of 30 different pieces of data collected, so the 15th and 16th pieces of data that would create the median. Both the 15th and 16th numbers would be in the 6 - 10.

If you find the average of the middle data point in each interval the mean would be approximately 7.2. This is in the 2nd interval (6-10).

Solve the equation on the interval [0, 2π). <br><br> cos x + 2 cos x sin x = 0

Take a common factor of cos(x)
$\cos(x) (1 + 2 \sin(x) ) = 0$
then by zero multplication rules
$\cos(x) = 0$
$x = \frac{\pi}{2} \: x = \frac{3\pi}{2}$
and when
$1 + 2 \sin(x) = 0$
so
$2 \sin(x ) = - 1$
$\sin(x) = \frac{ - 1}{2}$
so
$x = \frac{3\pi}{2} - \frac{\pi}{3}$
and
$x = \frac{3\pi}{2} + \frac{\pi}{3}$
