So this is our table:
-----------------
x-values | a b c d e f |
-----------------
y-values | g h i j k l |
-----------------
You can know that the values in the table are proportional if:

Hope that helps :)
C. The range is the difference of the value of the whiskers.
Remember: the range is the highest value subtract the lowest value.
Answer:

Step-by-step explanation:
We have

Put the coordinates of the given points and check the inequality:
For (0; 5) → x = 0; y = 5

For (2; 4) → x = 2, y = 4

For (1; 3) → x = 1, y = 3

Answer:
The answer is below
Step-by-step explanation:
a) The integral
means the total change in level of water in inches from 1 am to 10 am. That is the water level change measured in inches between 1 am and 10 am
b) 7 pm is represented as t = 19 hours, while midnight is represented as t = 24 hours, hence the water level change between 7 pm and midnight is:

c) Using casio calculator to evaluate the integral gives:
= 2.54 inches
D) The total daily change in water level =
= 0.35 inches
You'll have to multiply 0.7 by 120.
120*0.7 = n
n is the number that is 70% of 120
120 * 0.7 = 84
Hope this helps :)
