Times for an ambulance to respond to a medical emergency in a certain town are normally distributed with a mean of 400 seconds
and a standard deviation of 50 seconds.
Suppose there are 144 emergencies in that town.
In about how many emergencies are the
response times expected between 350 seconds and 450 seconds?

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
