A) Show that the equation 20-x^3-7x^2=0 can be rearranged to give x=20/x^2 - 7 b) using xn+1 = 20/x^2 - 7 with x0 = -9 find the values of x1, x2 and x3

c) approximation to the location of one of the roots of the equation.  Each iteration gives a slightly more accurate value of a root .

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
