Answer: 1,395 gallons
Step-by-step explanation:
There are 31 days in December.
If using this water fixture would reduce water usage to 45 gallons per day, the number of gallons to be used in December is:
= 45 * 31 days
= 1,395 gallons
The <em><u>correct answer</u></em> is:
She can determine that while there is an association between the variables, there is no correlation, and she cannot determine causation.
Explanation:
Since there is an arch shape to her graph, we know that as one variable changes, the other changes in the same manner. This means there is an association between the variables.
However, since the graph is not linear, there is no correlation between the variables. Since there is no correlation, we cannot determine causation.
Alright, lets get started.
Given information : Irene writes the check of 200 $ . It means the amount is deducted form here account.
Irene deposited 125 $ in her account. Means this amount is added in her account.
Suppose her initial amount in account was x $.
When she writes the check of 200 $, the amount is deducted so new balance is (x - 200) .
When she deposit amount 125 $, it means , the new balance of her account will be: 
Which shows her account is 75 $ less than her previous balance.
Hope it will help :)
You need to add a -1
We can find this by setting up the equation like so
x + (-6) + 12 + 15 / 4 = 5
x + 21 = 20
x = 20 -21
x = -1
Now if we insert -1 where x is located in the equation, you will get a means of 5
