Times for an ambulance to respond to a medical emergency in a certain town are normally distributed with a mean of 450 seconds and a standard deviation of 50 seconds
Suppose there are 288 emergencies in that town
In about how many emergencies are the response times expected between 400 seconds and 500 seconds?

dhhghghghhrhbb it 5

d

step-by-step explanation:

the answer will be b x² +x-1

step-by-step explanation:

6e14 is the answer.

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.
