Abel and zöe’s grandparents opened a savings account for an equal amount upon the birth of each child. now, the values of their accounts could be found by the following expressions, where t represents the years since 2011.

abel: y = 1266.77(1.03)t

zöe: y = 1159.27(1.03)t

based upon this information, find the difference in the children’s ages.

abel is
years older than zöe.
suggestions: find the ratio 1266.77/1159.26. what does that ratio represent in terms of powers of 1.03? you also can graph both equations and figure out the shift.

The weight of 46 new patients of a clinic from the year 2018 are recorded and listed below. construct a frequency distribution, using 7 classes. then, draw a histogram, a frequency polygon, and an ogive for the data, using the relative information from the frequency table for each of the graphs. describe the shape of the histogram. data set: 130 192 145 97 100 122 210 132 107 95 210 128 193 208 118 196 130 178 187 240 90 126 98 194 115 212 110 225 187 133 220 218 110 104 201 120 183 124 261 270 108 160 203 210 191 180 1) complete the frequency distribution table below (add as many rows as needed): - class limits - class boundaries - midpoint - frequency - cumulative frequency 2) histogram 3) frequency polygon 4) ogive
