Step-by-step explanation:
- 16-19 -> 3 (16, 17, 19)
- 20-23 -> 1 (21)
- 24-27 -> 3 (24, 26, 26)
- 28-31 -> 4 (28, 29, 30, 31)
- 32-35 -> 5 (32, 33, 34, 34, 35)
First thing you want to do, is reverse the question.
57/3 - 3.
57/3 = 19.
19 - 3.
Your answer is 16.
The formula of a slope:
We have the points (2, 5) and (4, 10). Substitute:
This means that 2.5mm of rain falls every hour
1,1,1,1,1
1x3=3
3-2=1
1x3=3
3-2=1
