1. solve. y-5 is less than or equal to 6 (1 point) a) y is less than or equal to 1 b) y is less than or equal to 11*** c) y is less than or equal to -11 d) y is less than or equal to 30 2. solve. 8 > d-2 (1 point) a) d < 10 b) d > 10 c) d < 6 d) d > 4 3. solve. 3.8 is greater than or equal to b + 4 (1 point) a) b is less than or equal to -0.2 b) b is less than or equal to 0.2 c) b is less than or equal to 7.8 d) b is less than or equal to 1.8 also, if anyone knows what the alt code is to make a less than or equal to, and a greater than or equal to symbols, that would be awesome. these are the only alt codes i know, °, •, ÷, ², ®, and √.

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
