For this case we have the following data:
Drained 3.5 Liters in 4 days. If we want to know the volume of water per day, we make a rule of three:
3.5 Liters -----> 4days
x Liters --------> 1 day
Where x represents the amount of water drained each day.
So, we have to:

Liters per day
So, the average change in water volume each day is:
Liters per day
Answer:
Liters per day
Answer:
c
Step-by-step explanation:
a.) 3(2)+4(6)= 6+24= 30
b.)3(6)+4(2)= 18+8= 26
c.)3(2)+4(-6)= 6+(-24)= -18
d.)3(-2)+4(6)= -6+24= 18
-18 is less than -1
Less than inequality sign means less than or equal to
Answer: there are 22 observations that are more than 116.
Step-by-step explanation:
Let x be the random variable.
Given: Sample size = 950
Mean = 78
Standard deviation = 19
The probability that the observations are more than 116 is given by :-

Number of observations are more than 116 = 

Hence, there are 22 observations that are more than 116.
