The arms pants were measured, in centimeters, for 12 students. The results are shown below

a) No. The stems should not be split

Step-by-step explanation:

14 |  8

15 |  1  4  5

16 |  0  1  2  2  7

17 |  0  1

18 |  0

The stem and leaf plot given in the example has the 150's and 160's split into two different stems which is not correct.

it is x=-4

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
