The exponential function is given in the form

where a is the initial value and b is the multiplicative rate of change
So lets plug the first two values of the table in this function , we get
or

Now plug second

Divide equation 2 by equation 1

On simplifying we get

or

So the multiplicative rate of change of the function is

Answer:
Boys - 36$ 33 cents
Girls - 72$ 67 cents
Step-by-step explanation:
Boys x
Girls 2x
Total 109
2x+x=109
3x=109/:3
X=36,3333
Boys x =36$ 33c
Girls 2x= 72,666= 72$ 67c
<u>Answer:</u>
- Colin will have $2365 after 3 years.
<u>Step-by-step explanation:</u>
<u>Using PRT/100, we can find the interest and then sum it up with the principle amount.</u>
- => 2200 x 2.5 x 3/100 = Interest
- => 22 x 2.5 x 3 = Interest
- => 55 x 3 = Interest
- => 165 = Interest
- => 2200 + 165 = Total amount
- => $2365
Hence, <u>Colin will have $2365 after 3 years.</u>
Hoped this helped.

1 and 1/10
i think that is what it is
Answer:

Step-by-step explanation:
The experimental probability is based on what already happened.
So we see that both of them found a total of 11 + 3 + 36 + 40 + 134 = 224 coins.
The coins that are worth MORE THAN 10 cents are 11 quarters and 3 fifty-cent pieces (we exclude dimes because we want MORE THAN 10 cents, NOT 10 cents exactly).
So 11 + 3 = 14 coins are worth MORE THAN 10.
So the probability of finding one worth more than 10 cents next is 14/224 = 1/16
