Linda tutors history. for each hour that she tutors, she earns 30 dollars.
let e be her earnings (in dollars) after tutoring for h hours.
write an equation relating e to h. then use this equation to find linda's earnings after tutoring for 30 hours.

E=30h

Step-by-step explanation:

E=30h when h=30

E=30(30)

E=900 dollars

E=30H

E=450

Step-by-step explanation:

30(15)=450

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.
