Sherelle and Venita find two bags of coins in their grandmother's attic. Each girl selects a bag, takes a random

sample of 20 coins from that bag, and lists the dates of those coins as the number of years since 1900. Here are

the results.

Sherelle: 72, 56, 81, 84, 75, 26, 39, 62, 65, 66, 85, 71, 74, 68, 73, 66, 83, 60,58, 72

Venita: 45, 65, 73, 57, 79, 66, 69, 75, 51, 44,53, 69, 58, 77, 51, 55, 53, 78, 70, 62

1. Find the five-number summary of each data set. Then construct box-and-whisker plots of the data sets. Draw

both plots above the same number line. Label the plots with the girls' names.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
