Answer:
The probability of a bulb lasting for between 480 and 526 hours=0.74454
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
102 loafs of bread
1232 ÷ 12 = 102.6666666666
102 is the answer
where is dx
I cannot find dx
