Last year there was 20 students in a class. this year there are 30% more students. how many students are in the class?

26

Step-by-step explanation:

To find the increase, we take the percentage increase times the original amount

increase = 30% * 20

increase = .30 *20

increase = 6

To find the new students in class, take the original student plus the increase

New class size = 20+6

                          =26

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.

translate k to n and reflect across the line containing jk.
