Let x be the jug,
for half-filled, y for the weight of the jug when empty.
∵
x + y = 2.6 kg
∵ x = 4 kg
∴
⋅ 4 + y = 2.6 kg
∴ 2 + y =2.6 kg
∵ y = 2.6 - 2 = 0.6 kg
∴ The weight of the empty jug = 0.6 kg
A) 10. You divide 5/4 to get 1.25 and multiply that by 8 to get 10.
Answer:

Step-by-step explanation:
Given:
Interval, [0, 4]
Required:
Average range of change over [0, 4]
SOLUTION:
Find f(0) and f(4) from the graph:
(when x = 0, y = 0)
(when x = 4, y = 3)
Average rate of change = 
Where,


Plug in the values into the formula for average rate of change.


Average rate of change
