The variance of a constant is zero. Rule 2. Adding a constant value, c, to a random variable does not change the variance, because the expectation (mean) increases by the same amount. ... Multiplying a random variable by a constant increases the variance by the square of the constant.
It would be 2.36686390533

Answer:
Step-by-step explanation:
I'm guessing your talking about long division,so to divide you Step 1: D for Divide. How many times will 5 go into 65? ...
Step 2: M for Multiply. You multiply your answer from step 1 and your divisor: 1 x 5 = 5. ...
Step 3: S for Subtract. Next you subtract. ...
Step 4: B for Bring down. ...
Step 1: D for Divide. ...
Step 2: M for Multiply. ...
Step 3: S for Subtract.
If its long you still do the same thing and if the decimal is in the divisor then you move the decimal that many times to the inside the bracket and stop at where the problem tells you or just leave it in its hundreths.
