-4 is correct.
Just convert the mixed numbers to decimals with a calculator then multiply.
Answer:
5900 units per year
Step-by-step explanation:
The average rate of change from (x₁, y₁) to (x₂, y₂) is the slope of the straight line joining the two points.
slope = (y₂ - y₁)/(x₂ - x₁)
From the graph, I estimate your points to be (2006, 35 000) and (2015, 88 000).
slope = (88 000 - 35 000)/(2015 - 2006) = 53 000/9 ≈ 5900 units per year
The average rate of change in the number of digital cameras sold between 2006 and 2015 was 5900 units per year.
Answer:
32d
Step-by-step explanation:
-The students ride their bikes to and from school every day. The distance is thus;

-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:

Now, we multiply the distance per day by the total number of days:

Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).
