1. Consider the tree diagram in the picture attached.
2 Each of the games picked can be a W (win) or a L (lose), the chances are equal
3. All that could happen in 4 picked games is shown in the picture:
2 w 2 l can happen in the following 6 ways: {(W,W,L,L)(W,L,W,L)(W,L,L,W)(L,W,W,L)(L,W,L,W)(L,L,W,W)}
4. P(2W,2L)=6/16=3/8

We have to complete the statement:
" The rate of change in the function y=x+4 is ______ the rate of change of the function represented in the table."
Let us consider the function represented in table.
The coordinates given in the table are:
(0,6) (2,8) (4,10) and (6,12)
Consider the first two coordinates (0,6) and (2,8)
Equation of line is given by
where 'm' is slope(rate of change) is given by the formula:
So,
So, equation of line is :
(y-6)= 1 (x-0)
y-6=x
y=x+6
Comparing it with standard equation of line y=mx+c with slope 'm'.
So, we get m(Rate of change)=1.
Now,
We will find the rate of change(slope) in the function y=x+4
Comparing it with standard equation of line y=mx+c with slope 'm'.
So, we get m(Rate of change)=1.
So, " The rate of change in the function y=x+4 is equal to the rate of change of the function represented in the table.
