Answer:
Option C) 0.2358
Step-by-step explanation:
We are given the following data set:
0.23105, 0.4725, 0.8765, 0.4865, 0.5326, 0.7976
Formula:
where are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 0.1122752556 + 0.008765640625 + 0.09633264063 + 0.006340140625 + 0.001123925625 + 0.05358067562 = 0.2784182787
Thus, the standard deviation for given data is
Option C) 0.2358
Given : A social media website has currently = 1,000 members.
In each month number of members gets triple.
To find: Equation that represents number of members m belongs to site.
Solution: Because we are given, each month the number of members gets triple, that means each month we can multiply by 3 to the number of members of previous month.
For first month, we would multiply 1,000 by 3.
For second month, we would multiply 1,000 by 3 *3.
For second month, we would multiply 1,000 by 3*3*3.
Each month one factor of 3 is being increasing.
We could write those 3's as exponents of 3.
Like
As many months as many 3's are there.
So, the exponent of 3 is represnts the number of months.
Let us take a variable for number of month by n.
So, we could setup an equation for number of members m belongs to site on a particular month n as
This is our final equation.
