5 At the end of her work day at the Ferguson Corporation, Sarah usually walks to the subway station to travel home. Today, she is walking to the Springdale Town Center first to take care of some errands. She will then continue walking to the subway station to travel home. The map of these routes is shown below.
If Sarah walks to the Springdale Town Center from the Ferguson Corporation and then to the Subway Station, how much farther will she walk than if she walks directly to the Subway Station from the Ferguson Corporation? Show all of your work.

Plz. yesterday, the snow was 2 feet deep in front of archie’s house. today, the snow depth dropped to 1.6 feet because the day is so warm. what is the percent change in the depth of the snow?

Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -5x + 4

Aprisoner is trapped in a cell containing three doors. the first door leads to a tunnel that returns him to his cell after two days of travel. the second leads to a tunnel that returns him to his cell after three days of travel. the third door leads immediately to freedom. (a) assuming that the prisoner will always select doors 1, 2 and 3 with probabili- ties 0.5,0.3,0.2 (respectively), what is the expected number of days until he reaches freedom? (b) assuming that the prisoner is always equally likely to choose among those doors that he has not used, what is the expected number of days until he reaches freedom? (in this version, if the prisoner initially tries door 1, for example, then when he returns to the cell, he will now select only from doors 2 and 3.) (c) for parts (a) and (b), find the variance of the number of days until the prisoner reaches freedom. hint for part (b): define ni to be the number of additional days the prisoner spends after initially choosing door i and returning to his cell.
