Answer:
To find the mean (average) all the # of workers and divide it by the data points. One way you can do this is through a calculator or even Excel spreadsheet.
Step-by-step explanation:
1) Add all them up
2) Divide them by the # of data points
You have write a fraction from the figure.
In the numerator you have write the total of shaded boxes (in the second figure: 6) and in the denominator you have to write the total of boxes ( in the second figure: 10)
So the answer is 6/10 and this makes sense because this represents the same fraction from first fraction
56.25 so yeah I hope that helps

Answer:</h2>
The simplified form of the given polynomial equation is:
<h2>
Step-by-step explanation:</h2>
We are asked to simplify the given polynomial expression in terms of the variable x.
The algebraic expression is given as:
On taking out the terms from both the brackets the sign of the terms of the second bracket gets interchanged as there is a negative sign preceding it.
Hence, we get the expression as:
Now on combining the like terms we get:
9514 1404 393
Answer:
A
Step-by-step explanation:
The second equation differs from the first in that -9 is a term added to both sides of the equation. The addition property of equality tells you that doing this will not change the value of the variable.
_____
The reason (not justification) for doing this is that the sum of 9 and its additive inverse is 0, the additive identity element. This means the equation can be simplified to 3x = 12, which is the point of making that step (subtracting 9).
