3 times 3 and 3 to the second power
First, find the mean. You'll need it to compute the variance.

The variance of the sample is then computed with the formula

The standard deviation is the square root of the variance, so
10.8 + 42 4/5 would be D) 53 3/5.
6.81 times 10^16 is the answer in scientific notation
Answer: If you are solving for m it would be -37 or 37 with the added negative
Step-by-step explanation:
34 = -(m + 3)
34 = -m - 3
+ 3 = -m + 3
37 = -m
