To do groups of 9, she could make 2 rows of 9. To do 3, she could do 6 rows of 3. Last, to do 6 she could do 3 rows of 6. :)
Y0ou find a common denominatior, in this case is 15.... then multiply whatever u had to get the denominator 15 times the top number, so 3/5 + 10/15 = 13/15
I hope this helps, I wrote the new equation each time you get a new number and where it should be placed
B because you need to do 2/6 which is the probability of getting a number above 4 times 1/2 the probability of getting heads. 2/6 x 1/2 = 2/12 = 1/2
Answer:
Option 3
The rate of change is -5%
Step-by-step explanation:
Given : An exponential function for compounding interest, 
To find : What is the rate of change?
Solution :
The general form of an exponential function is:

Where, a is the initial amount,
(1+r) is the rate of change,
r is the growth or decay factor
We have given, 
Rate of change is



Convert to percent,

Therefore, Option 3 is correct.
