The life of light bulbs is distributed normally. The variance of the lifetime is 225 and the mean lifetime of a bulb is 570 hours. Find the probability of a bulb lasting for at least 545 hours. Round your answer to four decimal places.

rick would give her the best deal as he will charge $8.88 per hour

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.

won't that be plagrisim thought?
