Continuous data are data which can take any values. Examples include time, height and weight. Because continuous data can take any value, there are an infinite number of possible outcomes.
Let the total number of people surveyed by y. we can solve this by using algebra.
to find the percentage of a number in terms of decimals or integers, just multiply the total by the percentage, so with this question, y x 40% = 20 shift x40% to the other side and turn it into /40% y = 20 / 40% change the percentage into decimals for easier calculations, y = 20 / 0.4 y = 50
