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 160 emergencies in that town.
In about how many emergencies are the response times expected between 400 seconds and 500 seconds?

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

they go with it happens or they mite give a chance?
