How long did real cowboys live? One answer may be found in the book The Last Cowboys by Connie Brooks (University of New Mexico Press). This delightful book presents 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:

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
(a) Make a stem-and-leaf display for these data. (Use the tens digit as the stem and the ones digit as the leaf.)
(b) Consider the following quote from Baron von Richthofen in his Cattle Raising on the Plains of North America: "Cowboys are to be found among the sons of the best families. The truth is probably that most were not a drunken, gambling lot, quick to draw and fire their pistols." Does the data distribution of longevity lend credence to this quote?

Sort of, these cowboys lived somewhat long lives, as evidenced by the high frequency of leaves for stems 5 and 6 (i. e., 50- and 60-year-olds).No, these cowboys did not live long lives, as evidenced by the high frequency of leaves for stems 4 and 5 (i. e., 40- and 50-year-olds). Yes, these cowboys certainly lived long lives, as evidenced by the high frequency of leaves for stems 7, 8, and 9 (i. e., 70-, 80-, and 90-year-olds).

a)

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

b)

Yes, these cowboys certainly lived long lives, as evidenced by the high frequency of leaves for stems 7, 8, and 9 (i.e., 70-, 80-, and 90-year-old).

Step-by-step explanation:

a)

Arranging the data in ascending order

47

52

57

58

58

61

66

70

97

Now the Stem and leaf plot of the data is given below

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

b)

The stem and leaf plot shows that cowboys lived long boys as the stem of 7 8 and 9 has higher frequency of leaves. Thus, the correct option is "Yes, these cowboys certainly lived long lives, as evidenced by the high frequency of leaves for stems 7, 8, and 9 (i.e., 70-, 80-, and 90-year-old)".

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
