Answer:
(-3,3)
Step-by-step explanation:
Using elimination:
Multiply the first equation by 8 and the second by 5 which equals
40x+56y=48
-40-60y=-60
Now you add them together
40x+(-40x)=0 so that crosses out
56y+(-60y)= -4y
48+(-60)=-12
You now have -4y=-12
Divide by -4
y=3
Now plug in y to any of the equations
5x+7(3)=6
5x+21=6
Subtract 21 from both sides
5x=-15
Divide by 5
x=-3
Your final solution is (-3,3)
(A) Mean best describes the amount of water in each bucket.
<h3>
What is mean?</h3>
- A dataset's mean (also known as the arithmetic mean, as opposed to the geometric mean) is the sum of all values divided by the total number of values.
- It is the most widely used measure of central tendency and is frequently referred to as the "average."
- In mathematics, particularly statistics, there are several types of means.
- Each mean is used to summarize a specific set of data, often in order to better understand the overall value (magnitude and sign) of a given data set.
- In two simple steps, we can calculate the mean or average of a data set: add up all of the values to find the sum.
- Subtract the sum from the total number of values in the data set.
Therefore, (A) mean best describes the amount of water in each bucket.
