B Euclid's chief of police is planning emergency routes. She needs to find the shortest route between the following pairs of locations:
Pair 1: the police station to City Hall
Pair 2: the hospital to City Hall
Pair 3: the hospital to the art museum
1. Give precise directions for an emergency car route for each pair.
2. For each pair, find the total distance in blocks a police car following
your route would travel.
С
1. The stadium is at (-2,3) and the high school is at (1,8). What is the
shortest driving distance (in blocks) between these two locations? Can
you figure this out without looking at the grid? Explain.
2. Suppose you know the coordinates of two landmarks in Euclid.
How can you determine the shortest driving distance (in blocks)
between them?
D
1. A helicopter can travel directly from one point to another. For each
pair in Question B, find the approximate distance (in blocks) a
helicopter would have to travel to get from the starting location to the
ending location. You may find it helpful to use a centimeter ruler.

In this problem, we explore the effect on the standard deviation of multiplying each data value in a data set by the same constant. consider the data set 14, 6, 8, 15, 15. (a) use the defining formula, the computation formula, or a calculator to compute s. (round your answer to one decimal place.) s = 4.28 (b) multiply each data value by 3 to obtain the new data set 42, 18, 24, 45, 45. compute s. (round your answer to one decimal place.) s = 12.83 (c) compare the results of parts (a) and (b). in general, how does the standard deviation change if each data value is multiplied by a constant c? multiplying each data value by the same constant c results in the standard deviation remaining the same. multiplying each data value by the same constant c results in the standard deviation being |c| times as large. multiplying each data value by the same constant c results in the standard deviation increasing by c units. multiplying each data value by the same constant c results in the standard deviation being |c| times smaller. (d) you recorded the weekly distances you bicycled in miles and computed the standard deviation to be s = 3.8 miles. your friend wants to know the standard deviation in kilometers. do you need to redo all the calculations? yes no given 1 mile ≠1.6 kilometers, what is the standard deviation in kilometers? (enter your answer to two decimal places.)
