Using the exponential distribution, it is found that there is a 0.3297 = 32.97% probability that a randomly selected part will fail in less than 20 hours.
<h3>Exponential distribution</h3>
The exponential probability distribution, with mean m, is described by the following equation:
In which 
is the decay parameter.
The probability that x is lower or equal to a is given by:
Which has the following solution:
In this problem, the mean and the decay parameter are, respectively, given by:
.
The probability that a randomly selected part will <u>fail in less than 20 hours</u> is given by:
0.3297 = 32.97% probability that a randomly selected part will fail in less than 20 hours.

Step-by-step explanation:
Answer:
W > 3
Step-by-step explanation:
im guessing you simplify. thats what i would do anyway
The sum of the interior angles of any polygon is (n-2)*180° (n being the number of sides) so for a triangle the sum of the interior angles is 180°. The sum of the interior and exterior angles is also 180°. To work out which sets are possible you subtract each number from 180° and then add all three answers together. If you get 180° then that set of numbers is possible. Using this method, you will find that the following sets <span>can be the measures of the exterior angles of a triangle:
</span><span>120°, 110°, 130°
</span><span>120°, 120°, 120°</span>
