If the variance of a dataset is 49.0, what would the standard deviation be, written as a float?

The standard deviation of a dataset is defined to be the square root of the variance value, which is easy seeing as you have a variance of 49; therefore, your stdDev would be 7.0. Since this has a python tag, if you were to import math, you could use math.sqrt(x) with x being your variance to come up with a value representing the stdDev
