Question

The stem and leaf plot shows kilometers walked by participants in a charity benefit walk. Use it to answer the questions.

Answer 1

Answer:

a. 35 people

b. 22 people

c.The range is calculated by getting the difference between the highest and smallest value.

d. Range=5.2km

Step-by-step explanation:

a. T o determine the number of people who participated in the walk, we count add the number of leafs per stem:

$6+5+8+9+5+2=35$

Hence, 35 people participated in the walk.

b. To find  how many of the walkers traveled more than 14 kilometers, we add those who walked distances greater than 14.0 km;

14 | 2 3 3 8 8 9 = 6 participants

15 | 2 2 2 2 2 3 5 5 7 = 9 participants

16 | 4 5 5 9 9 = 5 participants

17 | 3 5 = 2 participants

=6+9+5+2=22

Hence, the number of people who walked more than 14km is 22 people.

c. The range is calculated by getting the difference between the highest and smallest value.

The lowest value is 12.3

The highest is 17.5

Therefore, the range is calculated as:

$Range=17.5-12.3\\\\=5.2 \ km$

Hence, the range is 5.2km
