Elina [12.6K]

Answer:

$x=\frac{\pi }{6} ,\frac{7\pi }{6}$

Step-by-step explanation:

$3*cot^2x-1=0\\\\3*cot^2x=1\\\\cot^2x=\frac{1}{3} \\\\cot(x)=\sqrt{\frac{1}{3} } \\\\cot(x)=\frac{1}{\sqrt{3} } \\\\\frac{1}{tan(x)}=\frac{1}{\sqrt{3} } \\\\tan(x)=\sqrt{3} \\$

x=tan^-1( $\sqrt{3}$ )

It has to be in Quadrant 1 $\frac{+}{+} =+$ or 3 $\frac{-}{-}=+$ for positive.

$x=\frac{\pi }{6} ,\frac{7\pi }{6}$

Unless that incorrect due to tan(x) range is $-\frac{\pi }{2} \leq x\leq \frac{\pi }{2}$ . Then the only answer is $x=\frac{\pi }{6}$

Given a regular square pyramid with RS = 6 and PX = 4, find the following measure.<br><br> PY =

Dennis_Churaev [7]

Answer:

$PY=5\ units$

Step-by-step explanation:

we know that

Applying the Pythagoras Theorem

$PY^{2}=PX^{2}+XY^{2}$

In this problem we have that

$XY=RS/2=6/2=3\ units$

$PX=4\ units$

substitute

$PY^{2}=4^{2}+3^{2}$

$PY^{2}=25$

$PY=\sqrt{25}\ units$

$PY=5\ units$

The least likely measure of central tendency to be used would be; The range.

<h3>How to identify measures of central tendency?</h3>

We are given the points scored by the basketball team as;

84, 67, 74, 87, 67, 73

Now, the three major measures of central tendency are mean, median and mode.

Mean is the average while mode is the most frequent item while median is the middle term when arranged in ascending order.

However, when discussing their year, what the paper would like to know is their average amount of points per game for the year and as such he will use the mean.

However, the least likely measure of central tendency to be used would be the range.
