The mean time between failures (MTBF) is a common metric used to measure the performance of manufacturing systems. MTBF is the e

lapsed time between failures of a system during normal operations. The failures could be caused by broken machines or computer errors, among other failures. Suppose that the MTBF for a new automated manufacturing system follows an exponential distribution with a mean of 12.2 hours. (a) What is the probability that the automated manufacturing system runs for more than 18 hours without a failure

Answer:

0.2287

Step-by-step explanation:

The computation of the probability that the automated manufacturing system runs for more than 18 hours without a failure is shown below:

P(X > 17) = 1 - P(X < 17)

= 1 - [1 - e^-18 ÷ 12.2]]

= 1 - [1 -0.228684984 ]

= 0.2287

What is the radius of a circle with circumference 56 inches
pochemuha

Answer:

The answer is 8.91 or 8.9

Step-by-step explanation:

SInce the circumference is 56, you'll divide it by pi or 3.14. It's as if you're doing it backwards, but not always. After you divide it by 3.14, you'll get your diameter, or in this case, 17.8. Divide the diameter by 2 because the diameter is twice the radius. Eventually your final answer will be 8.91 or 8.9

How would you do 13 as a exponential
Ksenya-84 [330]

Hello! Welcome to Brainly! Let's solve together. :)

To put a number into scientific notation, you multiply it by a power of 10 that will make it a digit 1-10.

As you can see, we can divide by 10, or multiply by 1/10 to get us to 1.3, which is between 1 and 10. How would we get 1.3 to 13? We would multiply by 10!

This gives us our answer below.

1.3(10^{1})

I hope this helps!

Jackson used 1/5 of his savings for his first year of college. 2/3 of that money was spent on his tuition. Which equation shows
Law Incorporation [45]

1/5 was used for college

2/3 of that money used for college was spent on tuition

so we want to find the total amount used for tuition


we want to find 2/3 of 1/5

the eqaution would be \frac{1}{5} \times \frac{2}{3}=fraction of savings used for tuition

the fraction would evaluate to 2/15
