Use the data below to construct a stem and leaf display on your own paper. Determine if the determination form the book, Last Co
wboys by Connie Brooks (University of New Mexico Press), cowboys were by and large from good families and not necessarily young to die. They were not mostly drunkards, gun gunslingers, or thieves as portrayed in the movies. Does your stem and leaf display of the data support that finding? (answer yes or no). Cowboys: Longevity How long did real cowboys live? One answer may be found in the book The Last Cowboys by Connie Brooks (Univeristy of New Mexico Press). This delightgul book represents a thoughtful sociological study of cowboys in West Texas and Southeastern New Mexico around the year 1890. A sample of 32 cowboys gave the following years of longevity:
Given that a sample of 32 cowboys gave the following years of longevity:
58 52 68 86 72 66 97 89 84 91 91
92 66 68 87 86 73 61 70 75 72 73
85 84 90 57 77 76 84 93 58 47
The stem and leaf display for the data is given as follows: 4 | 7 5 | 2, 7, 8, 8 6 | 1, 6, 6, 8, 8 7 | 0, 2, 2, 3, 3, 5, 6, 7 8 | 4, 4, 4, 5, 6, 6, 7, 9 9 | 0, 1, 1, 2, 3, 7
that would be 20 miles per hour. If in 8 hours you're going 160, then divide 160 by 8 and you'd get 20. Each hour is 20 miles. or 8 times 20 is 160. Your answer is 20 miles per hour
Since the log is 20 m long, correct to the nearest metre and has to be cut into fence posts which must be 90 cm long, correct to the nearest 10 centimetres, there can be x fence posts 90 cm long.
So, we have x × 90 cm = 20 m
x × 0.9 m = 20 m
x = 20 m/0.9 m
x = 222.22
x ≅ 222 fence posts
So, the largest number of fence posts that can possibly be cut from the log is 222 fence posts.
