For a perfectly symmetrical distribution with a mean of 50, what is the value of the median?
1 answer:
In a set of data, if the data is perfectly symmetrical then the mean is equal to the median. In this case, the median would be 50.
For example, consider the data set: {25, 50, 75}
The mean is going to be 50 because = 50
The median is also 50 because that is the middle number when ordered numerically.
Hope this helped! Let me know if you have any more questions.

second option
Step-by-step explanation:
Substitute x = f(x) into g(x) , that is
g(f(x))
= g(x + 2)

The exact distance between two points L=(1,-3) and P=(8,-7)is 8.062 units, is obtained by formula and graphical method.
Step-by-step explanation:
The given is,
Two points are L=(1,-3) and P=(8,-7)
Step:1
By graphical method,
First point L (1,-3)
The values of x=1 and y=-3 noted in the graph
Second point P(8, -7)
The values of x=8 and y=-7 noted in the graph
Now join the points L and P, in the graph,
Distance between two points are 8.1 units
( OR )
Step:2
By formula method,
Distance =
Where,
L (1,-3) are ()
P (8,-7) are ()
Substitute the values,
=
=
=
=
Distance = 8.06225 units
Result:
The exact distance between two points L=(1,-3) and P=(8,-7)is 8.062 units, is obtained by formula and graphical method.
