Making a Prediction
try
In a population of 1,000 students, 50 were asked by
random sampling what their plans were after
graduation from high school. Their responses are
shown in the table
Using proportional reasoning, make a prediction
about how many students you would expect to have
plans to attend college

Write numerical coefficient of y² in the expression 2x² - 15xy – 7y²

What is the point of inflection for the function f(x)=2cos4x on the interval (0, pi/2)

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
