In Exercises 59 to 66, find the zeros of f. f(x) = x2 f(x) = x + 4x - 21
Normal Distributions (Day 3) 4/10/17 - Definitions - Density curve = curve: - Always on or above horizontal axis - Has area of exactly 1 underneath it - (describes overall pattern of distribution) - - Rather than enumerate the data for a histogram, we can estimate the number of observations in a certain range by looking at the area under the curve in that range. Normal Distributions (Day 3) 4/10/17 - If you consider a value x on the horizontal axis, we have: the area to the left of x is the proportion of scores (or values) less than or equal to x.
