Write an inequality for the following situation: I need at least 30 minutes to bake a cake. (Let t hours = the time needed.)

t > 0.5

Step-by-step explanation:

It is t > 0.5 because this specifies that the time needed to bake a cake is more than 0.5 hrs, or 30 minutes.

ok

step-by-step explanation:

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
