Marysya12 [62]

Answer:

2.0

Step-by-step explanation:

Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die

The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)

The first moment (AKA the average is..)

\frac{1+2+3+4+5+6+7}{7}=4

The second moment is..

\frac{1^2+2^2+3^2+4^2+5^2+6^2+7^2}{7}=20

\sqrt{20-4^2}=2

Solve these arithmetic: 2.75+0.003+0.158 =
olganol [36]
First, let's add 2.75 + 0.158.  First, we add the thousandths places.  Now, we have 2.758 + 0.15.  Next, let's add the hundredths place.  This is equal to 2.808+0.1.  Finally, we have the tenths place.  Now, our number is 2.908.

To finish this problem, we add 0.003.  2.908 + 0.003 = 2.911, so 2.911 is the answer to this problem.
