Ajar containing 100 pennies is dumped onto a table, and all those coming up heads are removed. the remaining pennies are placed back in the jar and the process is repeated several times. the results are listed in the table at the right. what is the equation of the exponential model fits the data?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
