Desmond builds a set of towers out of blocks. The table shows the number of blocks in each tower.
Tower #
1 2. 3. 4. 5
Number of blocks
5 10 20 40 80
Which explicit formula correctly represents the number of blocks, an, in terms of the tower number, n?
O A. an = n + 80
O B. an = 2n + 5
OC. an = 5(2)-1
OD. an = 10(5)

If you could answer these your a life saver

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
