Answer:
15.4
Step-by-step explanation:
mean is just the average of a set of numbers.
4 + 18 + 3 + 29 + 23 = 77
77 / 5 = 15.4
Well I need to know how many classes does the she teach and it would be 18
Pythagorean Theorem: a^2+b^2=c^2
(9)^2 + b^2 = (23)^2
81 + b^2 = 529
b^2 = 529 - 81
b^2 = 448
b^2 =

b = 21.2
