Answer: The confidence interval would be (0.2928,0.3672).
Step-by-step explanation:
Since we have given that
Total number of vehicles = 432
Number of SUVs sold = 142
So, it becomes,
At 90% confidence interval,
z = 1.645
So, the confidence interval would be
Hence, the confidence interval would be (0.2928,0.3672).
If you find the least common multiple of both numbers, this will give you the information you will need to get your answer. Each revolution would include all teeth going around. The list of multiples for 24 are 24, 48, 72, 96, 120. The list for 40 are 40, 80, 120. This means at 120, they would be in the same place again. For the first gear to get to 120, it would take 5 rotations the fifth number in the list of multiples for 24). I hope this helps!
Answer:
The probability is 0.5086
Step-by-step explanation:
The probability P that at least one of these three modules will fail to work properly is calculated as:
P = 1 - P'
Where P' is the probability that all the modules works properly. So, P' os calculated as:
P' = 0.9 * 0.84 * 0.65
P' = 0.4914
Because 0.9 is the probability that module 1 works properly, 0.84 is the probability that module 2 works properly and 0.65 is the probability that module 3 works properly.
Finally, the probability P that at least one of these three modules will fail to work properly is:
P = 1 - 0.4914
P = 0.5086
