The following data are arranged in ascending order and the median of the data is 60.
choli [55]
The median of the data is 60. That means the two middle numbers divided by 2 = 60.

(x + x + 2) / 2 = 60...multiply by 2
2x + 2 = 120
2x = 120 - 2
2x = 118
x = 118/2
x = 59

x + 2 = 59 + 2 = 61

so ur numbers go : 26,29,42,53,59,61. 70, 75, 82, 93

Gala2k [10]
Perimiter is 20ft
width is
what
do you mean the width is  8 feet less than the length? or 4ft less?

anyway

P=2(L+W)
20=2(L+W)
divide by 2
10=L+W
and
L=10-W

width is 4ft less than length (I assuming)
W=-4+L
repalce W with -4+L
L=10-(-4+L)
L=10+4-L
L=14-L
2L=14
L=7
W=-4+L
W=-4+7
W=3

it is 7ft by 3ft

10,388*2.5=25970

Now lets find the feet/week by multiplying that value by 7:

25970*7=181790

Now lets convert the feet to km:

181790/3281=55.4068881439

Resulting in approximately 55 kilometers
