This formula is used to find the median in a group data which is located in the median class. Median, m = L + [ (N/2 – F) / f ]C
L means lower boundary of the median class N means sum of frequencies F means cumulative frequency before the median class.
Hope this helps :))
It takes them 5 hours to drive 325 miles!
Since they travel 65 miles per hour, you multiply 65 x 5 and you get 325! Hope I helped :)

Answer: Line AC = 36
Step-by-step explanation: The first and most important clue is the fact that points B, D and F are midpoints of the triangle ACE. What this tells us is that point B divides line AC into two equal sides. Likewise points D and F. If point D divides line EC into two equal sides, then line ED equals
39/2 = 19.5
Also, triangle FED is similar to triangle AEC. Since ED is half of EC, and FE is half of AE. Therefore in triangles FED and AEC,
FD/ED = AC/EC
18/19.5 = AC/39
By cross multiplication we now have
(18 x 39)/19.5 = AC
702/19.5 = AC
36 = AC
Therefore line AC = 36
