Calculate distance FC
FC is calculated as:
Where
Considering 
, we have:
--- Pythagoras theorem
Where
and
So:
Take square roots of both sides
So:

Recall that:
So, its time to do some MATH!
ok so i would first approach this problem by placing the prices in order from least to greatest......um it would look something like this...(cue the math skills in my brain)
1.29,1.59,1.99,2..09, and last but most definitely not least (get it?) 2.19
so basically the median is like the MIDDLE number of your data (shout out to my fellow middle children!)
and so you may be asking "how does one figure this out?" and i will tell you that it is quite simple...
so what you got to do is cross out a number from the left and a number from the right, and you will be left with one number, which is your middle number (or in fancy maths language -the median- that was supposed to be said with a British accent, so just bear with me there :-))
and so your final answer should be....(drumroll please)
$1.99 is your median
(ta- da you are supermathematicalgeniuslevel smart)

Answer:
since BEC is an equilateral triangle, then each of its angles is equal to 60 degrees. what you get is: angle BEC = 60 degrees.
Step-by-step explanation:
x - c/2 = -3 c/2
Add c/2 to each side of the equation:
x = -2 c/2
Simplify the fraction on the right side:
<u>x = -c</u>
(this is for fractions!!!!!!!!!!!!) 28/5 or 5 3/5
i think u just make it into 5.6/1 multiply by 10 which gets 56/10 and wala
but it's not simplified. 56 and 10 is divisible by 2 so u get 28/5 which is actually 5 3/5 (which is 5.6!!)
