Step-by-step explanation:
We are given that
Standard deviation of the lifetime,
hours
Mean, 
hours
We have to find the probability of a bulb lasting for between 480 and 526 hours.
Hence, the probability of a bulb lasting for between 480 and 526 hours=0.74454

Answer:
-4
Step-by-step explanation:
Because when distrubuting first you distribute 2(-5) which gives you -10 and then you distribute 2 into 3 which is 2(3) which gives you 6. So now you have -10+6. So you can further simplify that into -4. We get -4 because -10 + 6 is -4. And the 4 is negitive because there are more negitives than positives.
