Step-by-step explanation:
2,2,6,15,38,39
6 and 15 are in the middle so add them
21 then divide by 2

Step-by-step explanation:
Answer:
C. 7.9 + x
Step-by-step explanation:
Given - A. 7.9x B. 7.9 · (-10) C. 7.9 + x D. - 79
To find - Which expression doesn't belong? Why does it not belong?
Proof -
As given
A. 7.9x
B. 7.9·(-10)
C. 7.9 + x
D. -79
As we can see that Option A, B, D are the multiple of 7.9 but Option C is not the multiple of 7.9
So, Option C does not belong here.
∴ we get
The correct answer is - C. 7.9 + x
The linear equation that is asked from the problem takes the
form of:
y = m x + b
where,
y = the median salary
x = the number of years
m = the slope of equation
b = y-intercept
The slope of the equation (m) can be calculated using the
formula:
m = (y2 – y1) / (x2 – x1)
m = (1326720 – 441300) / (2008 – 2000)
m = 110,677.5
The y-intercept is then obtained by using any of the data
pair:
441300 = 110677.5 (2000) + b
b = -220913700
Therefore the complete equation is:
y = 110677.5 x – 220913700
The median salary in 2016 is therefore:
y = 110677.5 (2016) – 220913700
y = $2,212,140
Answer:
$2,212,140
