You can break 98 into 2 49's. Hopefully, we know that 49 is 7 * 7, so 98 is 7 * 14. The correct answer is 14. :)
Answer: 0.1353
Step-by-step explanation:
Given : The mean of failures = 0.025 per hour.
Then for 8 hours , the mean of failures =
per eight hours.
Let X be the number of failures.
The formula to calculate the Poisson distribution is given by :_

Now, the probability that the instrument does not fail in an 8-hour shift :-

Hence, the the probability that the instrument does not fail in an 8-hour shift = 0.1353
Answer:
y = -2x + 4
Step-by-step explanation:
y = -2x + b
-8 = -2(6) + b
-8 = -12 + b
4 = b
Z=-3 is the correct answer. Use math papa if you need help with the steps on how we got z=-3
