∻Solution by Steps∻ ‖ step 1 ⋮ Count the number of data points in the stem-and-leaf plot that represent zoos with fewer than 50 bears. ‖ ‖ step 2 ⋮ Identify the stems that represent numbers less than 5 because the stem of 5 represents 50 and above. ‖ ‖ step 3 ⋮ Count the leaves for each stem less than 5. For stem 0, there is 1 leaf; for stem 1, there are 2 leaves; for stem 2, there are 7 leaves; for stem 3, there are 2 leaves; and for stem 4, there are 4 leaves. ‖ ‖ step 4 ⋮ Add the number of leaves from step 3 to find the total number of zoos with fewer than 50 bears: 1 + 2 + 7 + 2 + 4 = 16. ‖ ∻Answer∻ ⚹ 16 zoos ⚹ ∻Key Concept∻ ⚹Interpreting a stem-and-leaf plot⚹ ∻Explanation∻ ⚹The stem-and-leaf plot is used to determine the number of data points that fall within a certain range, in this case, the number of zoos with fewer than 50 bears.⚹◊How many zoos have more than 50 bears based on the given stem-and-leaf plot data?⍭ Generate me a similar question◊
