Answer:

Step-by-step explanation:
The average rate of change measures the average rate at which a function changes per unit time in a given interval. In another words, the average rate of change is the relationship between vertical and horizontal changes between two points of the function. So, basically if you are trying to find the average rate of change, you are trying to find the slope.

If
represents the months, then:
Let:

So:
For:


Therefore:

Answer:
Yes I can :O
Mean: About 11.87
Median: 11
Mode: 10
Step-by-step explanation:
Mean: Add up all the numbers and divide by the total number of numbers
<em>*deep breath in haha*</em>
6+7+7+8+8+9+9+9+50 (the 10s)+33 (the 11s)+12+12+12+12+13+14+14+16+16+17+17+18+18+19=356
356 (total) / 30 (number of numbers) = 11.8666666666666666666666 etc = 11.87
Median: With all the numbers in order, the middle number (if there are two add them together and divide by 2)
Not much to show, just mark them off starting from the outside getting inside, you end up with 11!
- See attached
Mode: Data value that occurs most often, in this case we can see that 10 happened the most
Hope this helps, have a nice day! :D
For any polynomial, first check to see if it factors. Then you can set each factor equal to zero.

The three zeros are -1,1,3
Next plug in values in each interval between zeros to test whether its greater than 0.
Try x values: -2,0,2,4
x = -2 yields a negative result, the interval x< -1 is Not a solution.
x = 0 yields a positive result, the interval -1
x = 2 yields a negative result, the interval 1
x = 4 yields a positive result, the interval x>3 IS a solution
The answer to this question is c. Hope I was able to help
