If 56% of the people at a certain conference are doctors, 42% are men, and 39% are malé doctors, what is the probability that a person selected at random at this conference is a doctor or man (or both)?
Write your answer as a decimal (not as a percentage).

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.

-1/4 > -1 2/3. -1/4 is greater than -1 2/3 because it is closer to 0 on the number line.
