Answer:
1. 30 minutes
2. 15 minutes
3. 30 minutes
4. 60 minutes/ 1 hour
5. 45 minutes
Step-by-step explanation:
1. 60 - 45 = 15
15+15 = 30
2. 30 - 15 = 15
3. 45 - 15 = 30
4. 60 - 30 = 30
30 + 30 = 60
5. 60 - 15 = 45
Answer:
0.674
Step-by-step explanation:
If the random variable X is exponentially distributed and X has an average value of 25 minutes, then its probability density function (PDF) is
and its cumulative distribution function (CDF) is
So, <em>the probability that X is less than 28 minutes is
</em>

Answer:
<em>28</em>
Step-by-step explanation:
4 squared is equal to 16
2 squared is equal to 4
16÷4=4
2 to the fifth is 32 (2x2x2x2x2)
32-4=<em>28</em>
