Answer:
Day 1: 12 is 40% and 18 is 60%
Day 2: 14 is 47% and 16 is 53%
Day 3: 13 is 43% and 17 is 57%
as for the second question, the reason why it's different for each day is probability, the probability can change with literally every movement like how hard you fling it or if there's outside interference like the wind.

Okay so the first thing we should do here is round 5.29 rounds to 5.30 3.59 rounds to 3.60 and 4.79 rounds to 4.80 now add all of those up youll get 13.7 you can round that to 14 so samanthas estimate is accurate
        
             
        
        
        
Answer:
u=54
Step-by-step explanation:
VX is middle line of triangle, so
VX=ZY/2.....(1)
 
We know that
Zy=u 
Vx=u-27
Put that in (1) we have:
u-27=u/2
2u-54=u
2u-u=54
u=54
