<h3>What is the Mean of a Data Set?</h3>
- Mean of a data set is the average of the data set.
- To calculated the mean of a data set, use the formula: Mean = (∑fx)/∑f).
Thus:
∑fx = 974
∑f = 28
Therefore:
Mean = 974/28
Mean = 34.8
In thousands, the mean salary for Linda's employees is 34,800.

Answer:
Correct option: C.
(Both Joey and Nolan)
Step-by-step explanation:
The step Joey did is:
Add 7x to both sides of the equation
Then, he got:
13x - 42 + 7x = 18 - 7x + 7x
20x - 42 = 18
The step Nolan did is:
Add 42 to both sides of the equation
Then, he got:
13x - 42 + 42 = 18 - 7x + 42
13x = 60 - 7x
So both of them used correctly the addition property of equality in the first step of their work.
Correct option: C.
3x-6+4=-20
- add 6 to both sides
3x+4=-20 +6
3x+4=-14
- then subtract 4 from both sides
3x=-14 - 4
3x=-18
- then divide 3 from both sides
-18 divided by 3 = -6
x= -6
