-4x=4
Step-by-step explanation:

So in this problem we need to do some addition.
take the starting balance (-200) and add it to the amount you paid back (30)
-200 + 30 = -170
So basically... you divide the 3 to 2 and that's how you get the decimal. The decimal is... 0.666666666667
Population mean = (7+8+6+6+6+4+4+1+2+7+6+1+1+1+3+3+5+4+5+7) / 20 = 87/20 = 4.35 <==
sample mean = (4+5+7) / 3 = 16/3 = 5.33 <==
A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. An equation that produces such a set of ordered pairs defines a function. What is the catch? There can be at most one output for every input.
