Mrs. ronilo had her students make a stem-and-leaf plot of the heights of all of the students in the class. the mean was 55. dave was absent the day they did this, and he is 57 inches tall. how does adding him into the data change the measures of central tendency?

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
