Factor out the GCF from the terms of the polynomial –4y^5 + 6y^3 + 8y^2 – 2y. I know that it is either B or D but I got confused

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2

Look at the chart showing the results of a baseball player at bat. which is the probability of getting a hit?

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
