Mean is average
triangle has 3 sides
mean of its sides is
if the sides are a,b,c meause then mean of the sides is (a+b+c)/3=mean=18

perimiter=a+b+c

therefor
perimiter/3=18

multiply both sides by 3
perimiter=54 yardds

I think this is the answer- so do 18x3 beacuse each side if the triangle is 18yards and a triangle has 3 sides! :)

Dunno if its right. :0

Answer:

-$0.26

Step-by-step explanation:

Calculation to determine the expected value of playing the game once

Expected value= [18/(18+18+2) x $5)]- [20/(18+18+2) x $5]

Expected value= ($18/38 x $5) - (20/38 x $5)

Expected value= ($2.37-$2.63)

Expected value= -$0.26

Therefore the expected value of playing the game once is -$0.26
