Company XYZ know that replacement times for the DVD players it produces are normally distributed with a mean of 8 years and a standard deviation of 1.8 years. Find the probability that a randomly selected DVD player will have a replacement time less than 2.2 years? P(X < 2.2 years)

if im not mistaking its

step-by-step explanation:  

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other

step-by-step explanation:

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
