Question 1098537: In regards to the half-life coin toss exponential decay experiment. (Toss 20 coins, remove all the ones showing heads, toss again and again removing all the heads each time. Amount of coins decreases by roughly half each time)

1) State an equation that best fits the results. Use n to represent the number of the toss.

My answer +y+=+n%281%2F2%29%5Ex+

2) State the exponential equation that would predict the number of remaining coins if you began with N° coins.

My answer: ?

Help me see the light, please.

You did fine. N=No(1/2)^x, where x= the number of tosses
With 100 coins, it should go 50-25-12.5
