Answer:
The answer is 7.
Step-by-step explanation:
Determine what values to use from the table to find the average rate of change.
The problem asks for the average rate of change (AROC) from week 3 to week 9. The points referring to these measurements would be (3, 41) and (9, 83), respectively.
Step 2
FInd the AROC from (3, 41) to (9, 83).
The formula for the slope of a line between two given points (which is the same as AROC from the first two the second point) is
AROC = y2−y1x2−x1
In your points, x1 is 3, x2 is 9, y1 is 41, and y2 is 83. Plug these values into the above formula and simplify.
AROC = 83−419−3=426=7
The AROC is 7.
Step 3
Enter your solution.
Enter the value 7 and move on to the next question.
