Suppose you converted the age distribution into a standard normal distribution. Find the z-score for a patient that is 45 years old and interpret what this value means in the context of the problem.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
