4 friends have more than 7 stickers and less than 13 stickers they share the stickers evenly how many stickers NEED HELP
mash [69]
Well,  there can be two answers. So, plus 3 other friends (4 people total) are sharing stickers.
To answer this, all you need to do is count by four. 
4 is not greater than 7 so can not be the answer
4+4 or 8 IS greater than 7 and less than 13 so it can be the answer
4+4+4 or 12 IS ALSO GREATER THAN 7 and less than 13 so it can be the answer
4+4+4+4 is 16 and is greater than 13 so it cannot be the answer
SO it is either 8 or 12 stickers

The table represents an exponential function.
Stels [109]

The exponential function is given in the form

y= a (b)^{x}

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

2= a(b)^1

or

2= ab............................(eqn 1)

Now plug second

2/5 = a(b)^2 .............................( eqn2)

Divide equation 2 by equation 1

\frac{2=ab}{\frac{2}{5}=ab^2}

On simplifying we get

5= \frac{1}{b}

or

b=\frac{1}{5}

So the multiplicative rate of change of the function is

a) \frac{1}{5}
