The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way.
For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.
For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.
Yes, you would try to simplify the equation as much as possible in order to get the variable.
Mean of 0,2,3,3,3,, 3,3,4,4,4,4,5,5,6
Deffense [45]
Answer:
3.5
Step-by-step explanation:
mean= 0+2+3+3+3+3+3+4+4+4+4+5+5+6=49
49÷14=3.5
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
