Tan 18 = opposite side/adjacent side
0.3249 = 4/adjacent side
and adjacent side = 4/0.3249 = 12.31
Now let's apply Pythagoras to find x
4² + 12.31² = x²
16 + 151.55 = x² and x² = 167.55
Then x = √167.55 and x = 12.94 ≈ 13
You will add them all together, then multiply the sum by 6.
713/6 = 118.833333
this rounded to the nearest hundredth

The median of the data is 6 and the IQR will be 4.
<h3>What are median and IQR?</h3>
The median is the number separating the greater half from the lower half of a sample data in probability theory and statistics. The interquartile range is a measure of statistical dispersion, or the spread of the data, in descriptive statistics.
To calculate the median first arrange the data in the increasing order and then find the mid value.
3,4,6,6,6,8,9,9,12
The middlemost value will be the median.
Median = 6
To calculate the IQR convert the data into lower limits and the upper limits from the median and then calculate the IQR.
3,4,6,6, |6| ,8,9,9,12
Lower Upper
Q1 = (4 + 6)/2 = 5
Q2 = ( 9+9)/2 = 9
IQR = 9 - 5 = 4
Therefore, the median of the data is 6 and the IQR will be 4.

Isolate the s. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
Subtract 19 from both sides
7 (-19) = 4s + 19 (-19)
7 - 19 = 4s
-12 = 4s
Isolate the s. Divide 4 from both sides
-12/4 = 4s/4
s = -12/4
s = -3
-3 is your answer for s
hope this helps
